China wholesale Mccb With Earth Leakage Protection - DAM1L-125 CBR ELCB Earth Leakage Protection Circuit Breaker – DaDa Detail:

This circuit breaker also has the following protection:
• It provides protection for fire hazards caused by grounding fault current that cannot be detected due to overcurrent protection.
• Provide protection against the danger of increasing ground voltage due to insulation damage;
• Circuit breakers with rated residual action current not exceeding 30mA can be used for personal contact protection.
• Circuit breakers with rated current of 500A and below can also be used for infrequent start, break off during operation and overload and short circuit protection of squirrel cage motors.
DAM1L series circuit breakers can be equipped with electric accessories and mechanical accessories for various purposes, such as separately excited tripping device, auxiliary contact, alarm contact and rotating handle operating mechanism.

This series of circuit breakers are widely used in construction, transportation, tunnel, residence, etc.The delay type in this series of circuit breakers is used for branch lines
Distribution of roads;Adjustable type is used to adjust the residual action current or disconnection time on site.

Advantages

•  Range:10A to 500A(AC)
•  integral structure, small volume, high breaking capacity, safe and reliable.
•  Adjustable magnetic setting(0.8-1times)In.
•  Push to trip button provision.
•  Separate main and arcing contacts
•  Can be adjusted the residual action current or disconnection time according to the actual use.
•  Strong anti-interference ability.
•  Wide range of accessories.

The working power of the residual current protection circuit of this series of circuit breakers is supplied by the multi-phase power supply (the working power of the protection circuit of early products is supplied by the single-phase power supply)the residual current protection circuit of the device can still operate normally.When the operating power voltage of the circuit breaker’s residual current protection circuit is reduced to 50V, the circuit breaker’s residual current protection circuit can still work normally.(I coherence n=30mA)

This series of circuit breakers are classified into B type (i.e., basic breaking capacity) (Inm less than 100), S type (i.e., standard breaking capacity) and H type (i.e High score breaking capacity (Inm > 160) can be used in different situations.

The main circuit of a circuit breaker is connected in many ways:
-Piston front connection
-Terminal extension plate front connection
-The screw connection at the rear of the piston plate
