Circuit protection principle


Basic PrinciplesThe proper selection of the correct circuit protective device requiresan understanding of the potential hazards against which protectionfor safety is required. The Wiring Regulations identify several hazards: electric shock thermal effects overcurrent undervoltage isolation

Electric shock - is divided into two parts: direct contact: contact with parts which result in an electric shock

in normal service indirect contact: contact with exposed conductive parts which re-

sult in an electric shock in case of a fault.

To protect against direct contact the Wiring Regulations suggest the following basic measures should be taken:(1) by insulation of live parts(2) by enclosures or barriers(3) by obstacles (4) by placing out of reach

To protect against indirect contact the Wiring Regulations suggest thefollowing basic measures should be taken:(1) earthed equipotential bonding and automatic disconnection of

supply(2) use of class II equipment or equivalent insulation(3) non-conducting location(4) earth-free local equipotential bonding(5) electrical separation

Of these five measures, the first is by far the most commonly used -(1) earthed equipotential bonding and automatic disconnection of

supply:

In each installation circuit protective conductors connect all exposedconductive parts of the installation to the main earthing terminal. Mainequipotential bonding conductors are used to connect extraneous conductive parts of other incoming services and structural metalwork to the main earthing terminal. These extraneousconductive parts include the following: main water pipes gas installation pipes other service pipes and ducting risers of central heating and air conditioning systems exposed metal parts of the building structure

This bonding creates a zone within which any voltages appearing be-tween exposed conductive parts and extraneous conductive parts,are minimized; the earth fault loop impedance must have a value lowenough to allow sufficient current to flow for the circuit protective de-vice to operate rapidly to disconnect the supply; disconnection mustbe sufficiently fast so that voltages appearing on the bonded metal-work cannot persist long enough to cause danger; depending on theoperating characteristics of the protective device and the earth im-pedance, such disconnection may be achieved either by overcurrent devices, Fuses, Miniature Circuit Breakers, (i.e. MCBs) orby Residual Current Devices, (i.e. RCCBs).

Thermal Effect - refers to heat generated by the electrical equipment in normal use and under fault conditions. The proper se-lection of equipment complying with the latest product standards isessential in providing protection against thermal effects.

Overcurrent - is defined as a current exceeding the rated value of thecircuit components. It may be caused by the overloading of a healthycircuit or it may take the form of a short-circuit current, defined as an"overcurrent resulting from a fault of negligible impedance between live conductors having a difference in potentialunder normal operating conditions". Overcurrent protection may beprovided by using fuses or circuit breakers singly or in combination.

Undervoltage - refers to the dangers that could be caused by the re-duction or loss in voltage and the subsequent restoration, such as theunexpected re-starting of motors or the automatic closing of protective devices. The proper selection of control and protective de-vices must take the protection against undervoltage into consideration.

Isolation - every circuit shall be provided with means of isolation (ex-cept in certain cases) to prevent or remove hazards associated withthe installation, equipment and machines. The new standards for cir-cuit breakers and switch-fuses now take this into account.

Protection against shock by indirect contactIndirect contact - is the contact of persons or livestock with exposedconductive parts made live by a fault and which may result in electricshock. An example would be where the insulation of an electricheater has broken down resulting in a live conductor internally touching the casing. This could result in the heater casing beingraised to a hazardous voltage level, causing electric shock to a person touching it.

Two important measures must be taken to prevent this hazard: the impedance of circuit conductors is kept to a minimum. The

earth fault loop impedance (Zs) is used as a measure of the circuit impedance under fault conditions.

the overcurrent device protecting the circuit is selected to rapidlydisconnect an earth fault.

The effect of these two measures is inter-related.1. By ensuring that the circuit protective conductor is of a low im-

pedance, the voltage to which the live casing is raised, underfault conditions, is kept to a minimum.

2. The low impedance path provided by the circuit conductors andthe circuit protective conductor will result in a high level of current in the event of an earth fault. This high fault current en-sures that the overcurrent protective device will disconnect thefault in a short time, reducing the interval during which the casingof the faulty equipment is live.

Components of earth fault loop impedance (Zs) in a system.(Earth fault at load between conductor and casing).Zs = Ze + (R1 +R2)

Fig 1

Earth fault loop impedance (Zs)To ensure the impedance of conductors in a circuit is sufficiently lowthe system designer has to establish the value of the earth fault loopimpedance.

Zs - is a measure of the earth fault current loop, comprising the phase conductor and the protective conductor. It comprises the complete loop including the winding of the transformer from which the circuit is supplied as defined by the following:

Ze - is the part of the earth fault loop impedance external to the installation, its value can be measured or a nominal value can be obtained from the supply authority.

Circuit protection principle


(R1 +R2) - where R1 is the resistance of the phase conductor within the installation and R2 is the resistance of the circuit protective conductor. These two components constitute theloop impedance within the installation.

Therefore: Zs = Ze + (R1 + R2)

Once the value of Zs has been established a suitable overcurrent pro-tective device has to be selected to ensure disconnection of an earthfault within the specified time.The times are: 5 seconds for fixed equipment. For portable equipment and for fixed equipment installed outside

the equipotential bonding zone, the disconnection times are dependent on the nominal voltage to earth, i.e. 220 to 277 volts = 0.4 seconds.

Zs by calculationTo establish whether the relevant disconnection time can be achieveda simple calculation must be made, based on Ohm's law:

Uoc (open circuit voltage)*If (fault current) = Zs (earth fault loop)

* voltage between phase and earth (240V)

The fault current (If) must be high enough to cause the circuit protective device to trip in the specified time. This can be es-tablished by consulting the time/current characteristic for the protective device. If the maximum trip time for the fault current calculated is less than or equal to the relevant value (5s for fixedequipment; 0.4s for portable equipment) then compliance isachieved. It is important that when consulting the characteristic curvethe worst case is used, i.e. the maximum tripping time including any tolerance. An example is shown in Figs 1 and 2.

Zs by tablesThe above procedure can be used for any type of protective deviceproviding a time/current characteristic curve is available. Frequently,however, a much simpler method is available using tables listing max-imum Zs values which have been interpreted from the characteristic curves for the relevant devices. Providing the systemZs is equal to or less than the value given in the table, compliance isachieved. Tables for a number of 'standard' devices (certain fusesand MCBs) are given in the Wiring Regulations.

Zs too highIf the system Zs value is too high to achieve rapid enough disconnection with the overcurrent protective devices available then itis necessary to use one of the two following methods: fit a cable with a larger cross-section and consequently a lower

impedance. This may be a very expensive solution especiallywhen the installation is complete before the problem is discovered.

use a Hager residual current device (RCCB). Subject to certainconditions being met this provides a simple and economical solu-tion.

Example

Fig 2

Fig 2 shows a fixed circuit with an earth loop impedance Zs of 0.7 ohms protected with an MT132. The fault current (If) willtherefore be Uo/Zs = 240/0.7 = 343A

By referring to the characteristic for MT132 (see Fig 3) it can be seenthat the breaker will disconnect in 0.02 seconds for this current. Thebreaker therefore easily satisfies the requirement for disconnection in5 seconds.If the circuit Zs was 2.0 ohms then the fault current would be:

240/2 = 120Aand the disconnection time would be 10 seconds, in which casecompliance would not be achieved.

Fig 3

Protection against overcurrentOvercurrent - "A current exceeding the rated value. For conductorsthe rated value is the current-carrying capacity"

Overload Current - "An overcurrent occurring in a circuit which iselectrically sound"

Short-Circuit Current - "An overcurrent resulting from a fault ofnegligible impedance between live conductors having a difference inpotential under normal operating conditions."

Protection against Overload CurrentFor the protection against overload current, protective devices mustbe provided in the circuit to break any overload current flowing in thecircuit conductors before it can cause a temperature rise which wouldbe detrimental to insulation, joints, terminations or the surroundings of the conductors.

In order to achieve this protection the nominal current of the protective device In should be not less than the design current of thecircuit Ib and that In should not exceed the current-carrying capacityof the conductors Iz, and that the current causing effective operationof the protective device I2 does not exceed 1.45 times the current-carrying capacity of the conductor Iz, expressed asIb < In < IzI2 < 1.45Iz

Protection against Short-Circuit CurrentProtective devices must be provided to break any short-circuit current before it can cause danger due to thermal and mechanical(electro-dynamic) effects produced in the conductors and connections. The breaking capacity of the protective device shall notbe less than the prospective short-circuit current at the point at whichthe device is installed. However a lower breaking capacity is permit-ted provided that a properly co-ordinated back-up device having the necessary breaking capacity is installed on the supply side(see page 153).

Positioning of Overcurrent DevicesDevices for the protection against overload and short-circuit must beplaced at the point where a reduction occurs in the current-carryingcapacity of the conductors. This reduction could be caused by achange in the environmental conditions as well as the more obviouschange in the cross-sectional area of the cable.

There are of course exceptions to this general rule which relate to avery few special applications. These are set out in detail in the WiringRegulations.

Technical information circuit breakers


Both of the new British Standards covering Low Voltage CircuitBreakers provide the user with a better assurance of quality and performance by taking into account the actual operating conditions ofthe breaker. New definitions and symbols have been introducedwhich should be committed to memory. Some of those most frequently used are:

Ue : rated service voltage

Ui : rated insulation voltage (> Uemax)

Uimp : rated impulse withstand

Icm : rated short circuit making capacity

Icn : rated short circuit capacity

Ics : rated service short circuit breaking capacity

Icu : rated ultimate short circuit breaking capacity

I n : rated residual operating current (often calledresidual sensitivity)

In: rated current = maximum value of current used for the temperature rise test

t: trip delay of residual current devices

In addition BS EN 60898 sets out to provide a greater degree ofsafety to the uninstructed users of circuit breakers. It is interesting tonote that the description "miniature circuit breaker" or MCB is notused at all in this standard, but no doubt both manufacturers andusers will continue to call circuit breakers complying with BS EN60898 miniature circuit breakers or MCBs for some time to come.

The scope of this standard is limited to ac air break circuit breakersfor operation at 50Hz or 60Hz, having a rated current not exceeding125A and a rated short-circuit capacity not exceeding 25kA.

A rated service short-circuit breaking capacity Ics is also includedwhich is equal to the rated short-circuit capacity Icn for short-circuitcapacity values up to and including 6kA, and 50% of Icn above 6kAwith a minimum value of 7.5kA. As the circuitbreakers covered bythis standard are intended for household and similar uses, Ics is ofacademic interest only. The rated short-circuit capacity of a MCB (Icn)is the alternating component of the prospective current expressed byits r.m.s. value, which the MCB is designed to make, carry for itsopening time and to break under specified conditions. Icn is shownon the MCB label in a rectangular box without the suffix A and is thevalue which is used for application purposes. Icn (of the MCB) shouldbe equal to or greater than the prospective short-circuit current at the point of application.

You will see from the curves that the inverse time / current characteristic which provides overload protection is the same on allthree. This is because the British Standard requires the breaker tocarry 1.13 times the rated current without tripping for at least onehour and when the test current is increased to 1.45 times the ratedcurrent, it must trip within one hour, and again from cold if the current is increased to 2.55 times the rated current the breaker musttrip between 1 and 120 seconds. The inverse time delay characteristic of all MCBs claiming compliance with BSEN 60898must operate within these limits.

The difference between the three types of characteristic curves designated 'B', 'C' and 'D' concerns only the magnetic instantaneous trip which provides short-circuit protection.

For type 'B' the breaker must trip between the limits of 3 to 5times rated current

For type 'C" the breaker must trip between the limits of 5 to 10times rated current, and

For type 'D' the breaker must trip between the limits of 10 to 20times rated current.

Often manufacturers publish their MCB tripping characteristics show-ing the limits set by the standard and guarantee that any breaker that you purchase will operate within these limits. So greatcare should be taken when working with characteristic curves showing lower and higher limits - on no account should you take amean point for application design purposes.

For cable protection applications you should take the maximum tripping time and some manufacturers publish single line characteristic curves which show the maximum tripping time. If thedesign problem is nuisance tripping then the minimum tripping timeshould be used and for desk top co-ordination studies, both lowerand upper limits have to be taken into account.

Energy limitingEnergy is measured in Joules. *James Prescott Joule proved thatthermal energy was produced when an electric current flowedthrough a resistance for a certain time, giving us the formula :-

Joules = I2 x R x t or because we know that watts = I2R

Joules = watts x seconds

Therefore we can say that :-

One Joule = one watt second

or energy = watts x seconds = I2 R t

If the resistance (R) remains constant or is very small compared withthe current (I) as in the case of short-circuit current, then energy be-comes proportional to I2t. Which is why the energy let-through of aprotective device is expressed in ampere squared seconds and re-ferred to as I2t

I2t (Joule Integral) is the integral of the square of the current over agiven time interval (t0, t1)

The I2t characteristic of a circuit breaker is shown as a curve givingthe maximum values of I2t as a function of the prospective current.

Manufacturers are required by the British Standard to produce the I2tcharacteristic of their circuit breakers.See Fig 8 on page 141.

The energy limiting characteristics of modern MCBs greatly reducethe damage that might otherwise be caused by short-circuits. Theyprotect the cable insulation and reduce the risk of fire and other dam-age. Knowledge of the energy limiting characteristic of a circuitbreaker also helps the circuit designer calculate discrimination withother protective devices in the same circuit.

Because of the importance of the energy limiting characteristic theBritish Standard for circuit breakers for household and similar installations suggests three energy limiting classes based on the permissible I2t (let-through) values for circuit breakers up to 32A;class 3 having the best energy limiting performance.

All Hager MCBs exceed the requirements for energy let-through setby the British Standard for energy limiting class 3.

Technical information circuit breakers


For use with DCBecause of their quick make and break design and excellent arcquenching capabilities Hager circuit breakers are suitable for DC ap-plications.

The following parameters must be considered.1 system voltage:

Determined by the number of poles connected in series (see table 13)

2 short circuit current:(see table 14)

3 tripping characteristics:- the thermal trip remains unchanged- the magnetic trip will become less sensitive requiring deratingby 2 the ac value. (see table 14)

Power lossThe power loss of MCBs is closely controlled by the standards and iscalculated on the basis of the voltage drop across the main terminals measured at rated current. The power loss of Hager circuitbreakers is very much lower than that required by the British Stan-dard, so in consequences run cooler and are less affected whenmounted together.

The table below gives the watts loss per pole at rated current.

Table 15

Temperature DeratingMCBs are designed and calibrated to carry their rated currentand to operate within their designated thermal time/current zoneat 30oC. Testing is carried out with the breaker mounted singly ina vertical plane in a controlled environment. Therefore if the circuit breaker is required to operate in conditions which differfrom the reference conditions, certain factors have to be appliedto the standard data. For instance if the circuit breaker is requiredto operate in a higher ambient temperature than 30oC it will re-quire progressively less current to trip within the designated time/current zone.

Grouping factorsConsideration should also be given to the proximity heating ef-fect of the breakers themselves when fully loaded and qmounted together in groups. There is a certain amount of wattsloss from each breaker depending on the trip rating which maywell elevate the ambient air temperature of the breaker above theambient air temperature of the enclosure.

grouping factor (rated current reduce by factor K)

ExampleFive circuit breakers are to be installed inside an enclosure in a switchroom which has an average ambient air temperature of35oC. Each circuit breaker will be required to supply a continuous current of 20A.

From Table 15 we would select a circuit breaker which has arated current of 25A at 30oC and 23.5A at 35oC. This takes care ofthe switchroom ambient air temperature of 35oC, but we alsohave to take into account the grouping factor of five continu-ously loaded breakers mounted together in one enclosure. Table 16 gives us a grouping factor K of 0.9. We thenapply this grouping factor to the rated current at 35oCwhich gives us a circuit breaker rated current of 23.5 x 0.9 = 21.15A in the specified conditions.

note: if the design current of a circuit (Ib) isless than 0.85 times the nominal setting of the circuit breaker (In)grouping factor can be ignored

Circuit breakers, and RCCB auxiliaries


FunctionsTripping and indication auxiliary contacts are common to therange of multi-pole 10kA MCBs, and RCCBs.They should be mounted on the left hand side of the device.

Auxiliary contact MZ201 (fig 9)Allows remote indication of the status of the device contacts towhich it is associated.

Auxiliary contact and alarm contact MZ202 This accessory has two separate functions.Like the MZ201 auxiliary contact, however the alarm contact will provide indication if the breaker trips under fault conditions.

MZ203 shunt trip*Allows tripping of the device by feeding the coil. The contactsalso allow for remote indication of operation.

MZ206 under voltage release* (fig 10)Allows the MCB to trip when the voltage drops or by pressing aremote off switch (ie emergency stop).

* Indication that the product has tripped due to the voltage release is provided by a flag on the product.
