Product Features

According to the level of the rated ultimate short-circuit breaking capacity, the breaker can be classified into four types. Type C (Basic type), Type L (Standard type), Type M (Less high breaking type) and Type H (High breaking type). The breaker possesses the features such as compactness, high breaking capacity, short arc over and short resistance etc.

The breaker can be installed vertically (upright) as well as horizontally (crosswise).

The breaker have disconnecting function. Its corresponding symbol is shown as :

The breaker meets the criterion IEC 60947-2, GB 14048.2-2001 and has TÜV, CE and CCC certificates.

Alarm Contact and Its Combination

Wiring Schematic of Alarm Contact

When breaker is open or closed normally ,the contact is

not actuated. Only after tripping or breaking due to

defect, the position of the contact will be changed from

permanently open to closed or permanently closed to

open. The contact resets when breaker re-latches.

Undervoltage Release

Control voltage: AC 50Hz 230V110VDC

400V220V

Between 35%~70% of rated control voltage, undervoltage release should operate in security and trip breaker. When under 35% of rated voltage, it should prevent breaker from closing. Breaker closing is possible only if the power supply voltage is no less than 85% of rated voltage.

Note: Only undervoltage release be charged in advance, breaker can be closed or re-latches.

Shunt release is usually installed in A phase of breaker. Between 70%~110% of rated control voltage, shunt release should trip breaker in security under any operating conditions.

Note: Below shunt controlling loop design is recommended when the power of the controlling loop is DC 24V.

KA stands for the relay in DC 24V controlling loop. The current capacity of its contract is 1A.

Rated Current (A)

Do not adjust the characteristic and accessories of the breaker, which handle by the

manufacturer.

The handle of the breaker can be placed in three positions, which represent CLOSED, OPEN

and FREE TRIP individually. When the handle is in the position of FREE TRIP, it should be

turned in direction of OPEN at this moment. Then the breaker can be re-latch and closed.

The user should conform to the regulations of the storage and application. Within 18

months after delivery from the manufacturer, if the product can not work properly or be

damaged because of the quality defect, the manufacturer is responsible for changing or

repairing without charge.

The model, specification and order quantity of the breaker should be noted. When using

undervoltage release, shunt release or motor operator, please give clear indication of

operation voltage or the value of control power voltage.

For example: NDM2-100L with undervoltage release and single auxiliary contact;

before-plate wiring type; Rated current 80A; Control voltage 220V; Quantity: 10 PCS. Then

you can order as following:
