Scope of application:
The SM40L series plastic case circuit breaker with residual current protection (hereinafter referred to as the circuit breaker) is one of the SM40 series products, which is a new type of circuit breaker developed by our company using international advanced design and manufacturing technology. Its rated insulation voltage is 800V, suitable for infrequent switching and motor starting in circuits with AC 50Hz, rated working voltage below 400V, and rated working current up to 800A. Circuit breakers have overload, short circuit, and undervoltage protection functions, which can protect circuits and power equipment from damage. It can also be used for personal electric shock (I Δ n ≤ 30mA) and equipment leakage protection, and can prevent fire hazards caused by grounding faults due to insulation damage of equipment.
