YBRM5DC-250 Series DC Molded Case Circuit Breaker

DC short circuits and overloads generate stubborn electric arcs, which easily damage battery packs and trigger dangerous fire accidents. The YBRM5DC-250 Series is a professional DC Molded case circuit breaker. It provides reliable electrical safety and targeted circuit protection for medium-current distributed new energy power systems. This specialized Molded case circuit breaker adopts DC-optimized arc extinguishing structure. It quickly extinguishes tough DC arcs and cuts off fault current in milliseconds. Calibrated thermal-magnetic trip technology adapts to frequent battery charge and discharge cycles. It effectively avoids unnecessary false tripping and ensures stable system operation. The high flame-retardant housing further reduces fire risks, greatly improving overall electrical safety for PV combiner boxes and small energy storage cabinets. Featuring a maximum DC current of 250A and optional 3P/4P poles, this Molded case circuit breaker runs steadily in -25℃ to 70℃ environme…
