YBRM5 - 400 Series Thermomagnetic Breaker
The YBRM5-400 Series thermomagnetic breaker is a high-current molded case circuit breaker, a heavy-duty MCCB tailored for energy storage stations and large industrial power systems, offering superior electrical safety and full-range circuit protection. Complying with IEC60947-2 and GB standards, it passes global project inspection and avoids overseas compliance barriers. This molded case circuit breaker adopts thick flame-retardant shell and oversized arc-extinguishing chambers with precise thermomagnetic trip modules. It delivers delayed tripping for overload and instant cutoff for severe short-circuit surges. Visible isolation and full insulation greatly boost electrical safety to prevent leakage, arc damage and costly electrical fires. Covering 200A–400A in 3P/4P poles, this molded case circuit breaker fits standard distribution cabinets for easy wiring. Reinforced mechanical structure maintains stable switching cycles under high heat, dust and humid harsh industrial environments.…
