SJKM1L-250/4300 plastic shell circuit breaker with residual current protection

Scope of application
SJKM1LE plastic shell circuit breaker with residual current protection (hereinafter referred to as the circuit breaker) is one of the new circuit breakers developed and researched by our company using advanced design software and manufacturing technology. Its rated insulation voltage is 800V, suitable for infrequent switching and motor starting in circuits with AC 50Hz, rated working voltage of 400V, and rated working current value of 800A. Circuit breakers have
The overload, short circuit, and undervoltage protection functions can protect the circuit and power equipment from damage, and also provide protection against potential fire hazards caused by long-term grounding faults that can be detected by the overcurrent protection unit
Circuit breakers are classified into two types based on their rated short-circuit breaking capacity (LCU): M-type (higher breaking type) and H-type (high breaking type). This circuit breaker has the characteristics of small size, high breaking height, short arcing, and anti vibration
This circuit breaker can be installed vertically or horizontally
