YBRM5E-630 Series Electronic MCCB

YBRM5E-630 Series Electronic MCCB

The YBRM5E-630 Series electronic molded case circuit breaker is a 400A–630A high-current MCCB for heavy industrial main power cabinets and large energy storage stations, delivering precise electrical safety and adjustable circuit protection. Certified to IEC60947-2 standards, it passes all global large power project acceptance inspections smoothly. Different from conventional thermal-magnetic breakers, this molded case circuit breaker adopts high-precision electronic trip modules. Users can freely adjust overload and short-circuit thresholds, and it maintains consistent accuracy free from temperature drift. Oversized arc-extinguishing chambers and visible isolation design greatly boost electrical safety to avoid leakage, arc ablation and destructive electrical fires. This molded case circuit breaker provides 3P/4P options, matching standard main distribution cabinets for fast wiring. Reinforced mechanical structure keeps stable switching performance under high heat, dust and humid ind…
