iALM1LE series residual current protection circuit breaker (hereinafter referred to as circuit breaker) is one of the new leakage circuit breakers designed and developed by our company with international advanced technology. lt is applicable to the AC 50Hz circuit with a rated voltage of up to 400V and rated current from 16A to 800A.
its main function is to provide indirect contact protection for personal electric shock with fatal danger. When other protective measures fail, the leakage circuit breaker with rated residual operating current not exceeding 30mA can also be used as supplementary protection for direct contact, but not as the only direct contact protection. it can also be used to prevent fire hazards caused by contact with fault current. Meanwhile, it can be used to protect the line from overload, short circuits, and other hazards. it can also be used for infrequent conversion of the line and infrequent startup of the motor.
The circuit breaker has the characteristics of small volume, high breaking, short arcing, adjustable residual operating current, and residual current operation time. At the same time, it can be equipped with an alarm contact, shunt release, auxiliary contact, rotating handle operating mechanism, electric operating mechanism, and other accessories. it can also adopt a variety of wiring modes such as front-panel, back-panel, and plug-in type. it is an ideal product for users.
Standards: GB/T 14048.2 and IEC 60947-2
