YBRM5E-400 Circuit Breaker Series

Medium and high current power systems face huge hidden risks. Overload and sudden short circuits easily trigger electrical fires, burn heavy-duty motors and bring costly factory downtime. The YBRM5E-400 Circuit Breaker Series is an upgraded Molded case circuit breaker. It prioritizes upgraded electrical safety and delivers full circuit protection for industrial parks, municipal power grids and large photovoltaic stations. This enhanced Molded case circuit breaker adopts optimized thermal-magnetic trip modules. It prevents false tripping during large equipment startup, and cuts dangerous short-circuit surges instantly. Reinforced flame-retardant casing and upgraded arc extinguishing structure stop arc leakage, greatly lifting on-site electrical safety. Comprehensive circuit protection fully protects main distribution cabinets and transformers from permanent damage. This Molded case circuit breaker supports 3P/4P optional poles, with rated current up to 400A. It runs reliably at tempera…
