690v photovoltaic circuit breaker direct current breakers rcm1-250x/2300 125a 200a 250a

Work environment:

 Below 2000m altitude; surrounding medium temperature not higher than +40°C (for marine products +45°C) and not lower than -5°C; able to withstand the impact of humid air; able to withstand the impact of salt mist, oil mist; able to withstand the impact of mold; able to withstand the impact of nuclear radiation; maximum inclination angle of 22.5°; can reliably work under normal vibration; can reliably work under earthquake conditions (4g); in media without explosive danger, and where the medium does not contain gases that are sufficient to corrode metals and destroy insulations, and conductive dust; in places without the invasion of rain and snow.

Product Features:

 Circuit breakers are classified into two major categories based on their rated short-circuit interrupting capacity (Icu): M-type (higher interrupting capacity) and H-type (higher interrupting capacity). Circuit breakers can be vertically or horizontally installed. These circuit breakers are characterized by their small size, high interrupting capacity, short arc-flight (some specifications have zero arc-flight), isolation, and vibration resistance. The residual current protection function of the circuit breakers has fire prevention and leakage alarm functions, providing protection against potential fire hazards and other dangers caused by ground faults that are undetectable by overcurrent protection.
