10A frame model is over 16% smaller with a width of just 36mm!!There is a saying that "every bit helps" and now with the industries smallest* general purpose Magnetic Contactor in its class, customers are able to more easily down-size their boards than ever before.
New integrated terminal coversThe perennial issues of remembering to order the terminal covers, fitting them correctly or loosing them in the process are challenges of the past. The integrated terminal cover system means they are always there, on the Magnetic Contactor or its Auxiliary contact, ready to be used.
The new ST series has new wide range operating coils which mean 50% fewer variations are required to span the 24-550V voltage range compared to the previous SN series. This means a smaller stock burden for those users who hold main stock or spare parts.
Tropicalization treatment, anti-corrosion treatment and low temperature-response capabilities are now standard in the S-T type Magnetic Contactor range, so our customers do not need to worry about which version they are ordering.(note MSO-T and TH-T Magnetic Starters and thermal overloads have anti-corrosive treatment only)
Actual size
*based on a survey of 10A frame class Magnetic Contactors conducted for Mitsubishi Electric September 2012

The integrated terminal covers have an additional benefit in that they act as a guide to improve wiring efficiency but also retain the terminal screw in place: no mislaying the screw, no dropping it or having trouble reinserting it in to the terminal block just fast efficient wiring. Fast wiring terminals (model name with suffix “BC” ) are also available to further improve wiring efficiency, workability and hence productivity.

Magnetic Contactors(Without Thermal Overload Relays, Open type)
Contact reliability of main and auxiliary contactsThe minimum working voltage and current of the main and auxiliary contacts of the S-T type Magnetic Contactors and the contact
of the SR-T type Contactor Relays vary depending on the allowable failure rate. Apply the following diagrams.
■The contact reliability reduces when a contact is connected in series or when the current is applied and broken at
the time of opening and closing the contact.
Prescribe remedies such as connecting the contact in parallel (providing redundancy).
■The contact must be connected in parallel (providing redundancy) if reliability greater than the contact reliability
shown the diagrams 1 to 3 is required.

Note 1: The contact reliability indicates the failure rate λ60 (the number of failures/the number of opening and closing operations, per contact) at 60% reliability standard. This reliability is applied when the product is in use under a clean atmosphere in the standard specification environment (Refer to page 44).Note 2: The contact resistance of the contacts may change due to economical corrosion and that may affect the contacts in the case of a light load.
It is recommended that regular inspections to be conducted, with load opening and closing performed several times in the inspection, and that consideration be provided on the system side.

DisassemblyThe Thermal Overload Relays are adjusted at the time of assembly. Do not disassemble it.
Ambient temperature compensationThe TH-T type Thermal Overload Relays are adjusted with the Magnetic Starters in the standard box (the MS type) relative to the ambient temperature of 20°C (The temperature on the control board of the MSO type Magnetic Starters is 35°C). The ambient temperature compensator is mounted on the TH-T type Thermal Overload Relays. Therefore, the ambient temperature less affects the operational characteristic change. The minimum operating current change according to the ambient temperature change relative to the ambient temperature of 20°C (the temperature on the control board of 35°C) generally depends on the characteristics in the diagrams 1 and 2.The Thermal Overload Relays have a characteristic that the operating current becomes high when the ambient temperature is low and becomes low when the ambient temperature is high. If the ambient temperature of the installation site is significantly different from 20°C (the temperature on the control board of 35°C), the setting current of the Thermal Overload Relays needs to be corrected as shown in diagrams 1 and 2. In addition, note that the compensation factor has a characteristic to be the minimum scale>middle scale>maximum scale at the adjustment knob location. (Note that the Thermal Overload Relays may operate at a current of less than 100% stabilized current if in use at temperatures exceeding the allowable working temperature of 40°C (55°C).)
Connecting electric wire size and operating currentThe TH-T type adjusts the minimum operating current with the standard electric wire size shown in the following table. If the electric wire is thicker or thinner than this standard electric wire size, the operating current becomes high or low, respectively. Therefore, correct the stabilized current (divide it by the change rate of the minimum operating current) to use a size different from the standard connecting electric wire size.
Note 1: [*1] The ambient temperature applied to the MS type indicates the outside temperature of the box. [*2] The temperature including temperature increase on the control board applied to the MSO type is indicated.
For the information on the connecting electric wire size, refer to page 46.

Usage environment(1) Ambient temperature : -10°C to 40°C (Applied to the outside of the control board) Average daily atmospheric temperature: 35°C (Max.), Average yearly atmospheric temperature: 25°C (Max.)(2) Maximum temperature of the : 55°C However, the ambient temperature of boxed MS type is 40°C (Average yearly temperature of the inside of the control board is 40°C or less.). inside of the control board Please note that the operating characteristics of the Magnetic Contactors and Thermal Overload Relays may vary with the ambient temperature.(3) Ambient temperature : 45% to 85% RH However, dew condensation and freezing should be avoided.(4) Height above sea level : 2000 m or less(5) Vibration : 10 to 55 Hz, 19.6 m/s2 or less(6) Impact : 49 m/s2 or less(7) Atmosphere : Inclusion of dust, smoke, corrosive gas, moisture, salt content and the like in the atmosphere should be avoided as much as possible. Please note that continuing to use the device in a closed condition for a long period may cause contact failure. Never use the device under an atmosphere that contains flammable gas.(8) Storage temperature/Relative humidity : -30°C to 65°C 45% to 85% RH However, dew condensation and freezing should be avoided. The storage temperature is ambient temperature during transportation or storage and should be within the usage temperature when starting to use the device.
Mounting
(1) The device should be mounted in a dry location low in dust and vibration.(2) The normal mounting direction is the direction shown in Fig. 1 on a vertical surface, but mounting the device at an inclination angle of up to 30 degrees in either direction is allowed. (Fig. 2)(3) Mounting the device on a floor or ceiling is not allowed. (Mounting the device on a floor or ceiling may affect the continuity performance, operation performance, and durability of the contact.)(4) If mounting the device in a horizontal orientation cannot be avoided, be sure to rotate the device by 90 degrees in a counterclockwise direction from the normal mounting direction as shown in figure 3 when mounting it.
If the device is mounted in a horizontal orientation, its characteristic is nearly unchanged but mechanical durability may be deteriorated. Horizontal mounting of reversing type is not allowed.
●Tightening torque of mounting screwThe device should be mounted by force of tightening torques shown in the right table.

About Handling Note
Precautions for Use
●PerformanceThe performance described in this catalog is based on the result of a test conducted under the conditions specified in the Standard (IEC60947-4-1 "Low-voltage switchgear and controller" etc.). If actual use condition is different from this test condition, the user must evaluate the condition (by using an actual device).
●Use conditionAlthough the device can operate without any problem when under the conditions described in this chapter, be careful about the following matters.(1) Ambient temperature
Even when the device is used in accordance with normal usage, deterioration of the insulation will progress.In particular, as the ambient temperature increases, the insulation life is shortened. In general, it is said that every time the ambient temperature increases by 6 to 10°C, the insulation life decreases by half (Arrhenius law). In a case where the ambient temperature is high and voltage exceeding the rated voltage is continuously applied to coil, the coil temperature increases and life may be shortened dramatically.
(2) Vibration/ImpactAlthough vibration of 19.6m/s2 and impact of 49m/s2 do not cause contact malfunction, even when the vibration and impact are below these values but are applied continuously, fatigue failure may cause some trouble.In particular, please note that the resonance of an installed board may exert a large vibration on the product.
Be sure to periodically check the Magnetic Starters and apply danger prevention measures on the sequence of important circuits. (The Magnetic Starters contacts may suffer from defective continuity, welding, and burning. )
When performing installation, wiring, and maintenance & inspection, be sure to disconnect the Magnetic Starters from the power supply. It may cause electric shock. In addition, the malfunction attributable to vibration, impact, and false wiring may exert serious results (machine malfunction, short-circuiting of power supply, etc.) on the Magnetic Contactors.

Mounting space and arc space
●Mounting space and arc space
Note 1. The value of this arc space is a value of IEC and JIS Standards-based closed circuit shut-off capacity test.Note 2. Although the B dimension of T10 to T32 allows closely-attached mounting, when continuing to apply current to
the device or when mounting a product high in open/close frequency and high utilization on the same rail, the device life may be shortened in terms of temperature increase and impact, so please keep the space between the devices over the minimum value shown in the above table as much as possible when mounting them.

Connection●Applicable electric wire size and tightening torque and terminal dimension of terminal screw
This may cause overheating or fire. Be sure to properly keep the tightening torque and periodically re-tighten the screw.However, please note that tightening the screw under the status where oil is adhered to the terminal portion may damage the terminal screw even within the existing tightening torque.Electric wires should be properly connected according to the electric wiring diagram. Tightening the terminal screw should be properly conducted within the tightening torque shown in the right table. Insufficient tightening of the terminal screw may cause overheating or cause the electric wire to drop off. Excessive tightening torque may damage the tightening screw.Adhesion of rock paint, thermo label, etc. to electric wire connection or contact may cause heat generation due to defective continuity, so this is very dangerous.
The main circuit terminals of T10 to T32 and TH-T18/T25 types are allowed to be connected via any of single wire, stranded wire, and crimp lug. The main circuit terminals and operating circuit terminals of T10 to T32 and TH-T18/T25 types are self-up terminals, which facilitate wiring.
●Power supply voltage variation range and voltage drop of the operating circuit(1) Operating voltage
When the rated voltage and frequency are applied to the coil at an ambient temperature of 40°C (Inside temperature of the board: 55°C), the device operates without any problem at 85 to 110% of the rated voltage of the coil after the temperature increases and becomes saturated.
(2) Voltage dropEven when the coil is excited at the rated voltage and the voltage drops to 65% of the rated voltage (first 1 to 2 cycles; however in case of 0.1 second or more, 70%) when the main contact is contacted, contact welding does not occur at a current ten times the rated operational current, allowing the device to operate without any problem.
(3) Voltage/Frequency and coil rating of operating circuitThe voltage/frequency of the operating circuit and the same of the operation coil must be matched.Applying a voltage exceeding 100% of the rated voltage to the operating circuit when using the coil may acceleratedly deteriorate the coil insulation and consequently reduce mechanical durability, so set the coil's average voltage to 95 to 100% of the rated voltage when using the coil.
Operating circuitApplying a low voltage that does not operate the Magnetic Contactors to the operating circuit may cause overcurrent to the coil, which may cause the coil to be burned in a short time.
If the operating circuit wiring is too long, when the coil's instantaneous current flows, the wiring impedance may cause a reduction in the coil voltage, so that the operating circuit may fail to be activated. And, the stray capacitance of the wired line may cause the coil's excitation not to be released even when releasing the excitation.

Note 1: The dimension of the main circuit terminal is a dimension for board conductor wiring. (See the right diagram) The board conductor
thickness (D dimension) must be below the allowable connection conductor thickness stated above because of the length of the terminal
screw. In case of wiring with two boards used, the total value of two boards must be below the value (D dimension) shown in the table.
Note 2: In each terminal, two wires or two crimp lugs are allowed to be connected.
Note 3: The cross slot screws with pressure plate of T Series and those of N or other Series are same in size but different in pressure plate
dimension, so please avoid the mixed use of such screws. This may break the insulation barrier or make the wire likely to fall out.
Note 4: When using IEC60529-based finger safe specification, be sure to use an insulation tube-attached crimp lug.
Note 5: Tightening the3 terminal screw excessively without wiring may break the screw and consequently disable the tightening, so please avoid
such excessive tightening.
Note 6: Operational circuits are coil terminals of Magnetic Contactors and control circuit terminals of Thermal Overload Relays.
Note 7: Please use swaging tool which is recommended by JST.

●Low temperature
●Corrosive gas
●Dust
When using Magnetic Starters or Magnetic Contactors at high ambient temperature, the temperature may mainly affect the insulation life (continuous electric conduction life) of the operation coil and the aging variation of the molding component.MSO and S-T type without a box are standard products available even at the inside temperature of 55°C.
Although the Magnetic Contactors may be transported to a cold region or used in such a cold region or under cold conditions such as those found in a refrigerator with the contactor incorporated in a switchboard, the S-T type Magnetic Contactors is applicable as a standard product. Also, MSO-T type Magnetic Starters and TH-T type Thermal Overload Relays of low temperature specification are not manufactured. Applicable temperature range of low-temperature-based products: -50 to 55°C (Operating temperature) -60 to 65°C (Storage temperature)
S-T type Magnetic Contactors is of corrosion resistance-increased specification as a standard product.Corrosive gases that exist in an environment with an Magnetic Starters or Magnetic Contactors used are gases such as sulfurous acid (SO2), hydrogen sulfide (H2S), chlorine (Cl2), and ammonia (NH3), and conductive portions can be protected by plating a metal resistant to such gases on the portion. However, because there is no adequate corrosion prevention method for the contact, such gases may increase the contact resistance, resulted in increased temperature.Additionally, if the environment contains some corrosive gas but is under dry condition, this may delay the progression of corrosion, so using the switchboard with the inside kept as dry as possible is also one of the corrosion prevention methods.In the Magnetic Starters and Thermal Overload Relays, corrosion-prevented products (MSO-T□YS, TH-T□YS) of the specification with increased corrosion resistance to such corrosive gases are also manufactured.
Magnetic Starters and Magnetic Contactors used in an iron foundry, construction site, or powder conveying machine tend to be subject to a relatively large amount of dust. When using the control board in such locations, the board must be dust-prevention-structured. Also, using the board under hermetically-sealed condition for a long period may cause contact failure.
●Export of the products to tropical regionsThe environment of exported products which pass through tropical regions tends to be of high temperature and high humidity, and humidity is the environmental factor that affects the Magnetic Starters and Magnetic Contactors most severely. Humidity is the biggest rust-generating factor and the exported products must be in a structure resistant to humidity.Therefore, it is recommended to put a moisture absorbent (Silica gel) in an amount of 3kg or more per m³; so as to lower the humidity.
●High temperature
Application to special environmentPlease note that the operating characteristics of the Magnetic Contactor and Thermal Overload Relay may vary with the ambient temperature.

Danger
●Use the product in the use environment described in this catalog and Instruction Manual. Do not install the product in any abnormal environment with high temperature, high humidity, dust, corrosive gas or excessive vibration/shock. There is a risk of catching fire, malfunctions, electric shock or failure.●Avoid applying shocks by dropping or falling the product during transportation and unpacking. This will lead to breakage or
failure of products.●Do not use the product when it has received damage during transportation, installation or wiring. This can cause fire or
malfunctions.●Make sure that only technicians qualified for electric work or wiring should perform installation, wiring works and
maintenance/checking of the product.●Make sure that no foreign objects such as dust, iron powder and wire chips enter the product during installation and wiring
works. There is a risk of contact failures and malfunctions leading to damage or fire at the load.●When you use mounting screws of the wrong size or use a small number of screws than specified, or when the mounting to
the rail of IEC 35mm width is defective, there is a risk that the product may fall.●When you apply wiring works, be sure to use the wire size that suits the applied voltage, flow current and inrush current,
and to fasten wires with the correct torque as specified in this catalog or the instruction manual. Defective wiring can cause fires, accidents and failures.●To terminal screws and mounting screws, apply the torque as we specify for tightening, and regularly apply retorquing.
When the tightening torque is too large, the work can damage terminal screws or mounting screws. When the terminal screws or mounting screws slacken or are broken, they can cause overheat or fire, or the body can fall off to create serious accidents.●Confirm the rated values and specifications, and make sure to use a product that meets the requirements. When you use a
product exceeding the rated/specified values, it may cause insulation breakdown leading to earth fault or short circuit accidents, or create the cause of fire by overheat or breakdown due to inability to shutdown.●When a product described in this catalog is to be used in a facility where a failure can lead to injury to the human body or
serious damage to earnings, make sure to install some safety mechanism.●Apply regular checks to the product and use safety measures on the sequence to the critical circuits. The contacts of
Contactors and Magnetic Starters can develop defective conduction, weldingor burnout.●Contactors and Magnetic Starters can create welding of contacts disabling the opening, due to such causes as switching
operation for excessive current, abnormal wearing of contacts, chattering at operational instruction contacts, aging degradation and product life. Also the contacts may fail to open due to unexpected mechanical constraints other than contact adhesion. Since the disability of contact to open can cause the machine to go out of control, secure safety by assuming the mechanical constraints or contact welding leading to inability of open/close operations. There remains a risk of fire even when an overload protective device (Thermal Overload Relays) is provided.●The example connection described in this catalog only shows a typical one to run a system. For the protection of each
device and safety measures, the customer is requested to consider the connection for each system.●Do not apply reworks to the product or disassemble the product. These may cause failures.●When you dispose of the products, treat them as industrial waste products.
