Applications of YSM1 Photovoltaic DC Molded Case Circuit Breaker
YSM1 series PV DC circuit breakers are suitable for DC network circuits with rated voltage of up to DC 1000V and rated current of up to 630A. DC circuit breakers have overload long delay protection and short-circuit instantaneous protection functions, which are used to distribute electrical energy and protect lines and power supply equipment from overload, short-circuit, and other faults. The operating mechanism of the DC circuit breaker has a fast closing and fast-breaking function, a compact structure, a small size, and is easy to use.
