Adaptation Molded Case Breaker: YBRM5-400 Circuit

Uncontrolled overload and high-current short circuits burn main power cabinets, halt medium factory production and trigger costly fire rectification fees. Our YBRM5-400 Thermomagnetic Circuit Breaker acts as a mid-high current heavy-duty Molded Case Breaker and all-in-one Electrical Protection Device for 50/60Hz low-voltage systems with rated current up to 400A.   This practical Molded Case Breaker adopts integrated thermomagnetic trip modules for dual-layer safety. Thermal bimetals avoid frequent tripping under light overload to guarantee stable power supply, while magnetic units instantly cut short-circuit surges to suppress dangerous electric arcs. Its thick flame-retardant reinforced shell operates steadily from -25°C to 70°C with dust and moisture resistance. It supports optional 3P/4P poles and expandable alarm, interlock and shunt trip accessories for automated power control.   Ideal for high-rise main distribution boxes, medium manufacturing plants and commercial complex power…
