YBRM5 - 250 Thermomagnetic MCCB

Uncontrolled overload and sudden short-circuit faults easily burn medium-power motors, shut down supermarket and workshop production, and lead to expensive electrical fire losses. Our YBRM5-250 Thermomagnetic Circuit Breaker serves as a mid-current heavy-duty Molded Case Breaker and all-in-one Electrical Protection Device for 50/60Hz low-voltage distribution systems with 250A rated current.   This reliable Molded Case Breaker adopts integrated thermomagnetic trip modules for dual safety control. Thermal bimetals delay tripping to avoid unnecessary power cuts under mild overload, while magnetic components instantly cut surge current to suppress dangerous electric arcs. Its high flame-retardant shell supports stable operation at -25℃~70℃, with dust and moisture resistance. It offers flexible 3P/4P poles and optional interlock & alarm auxiliary parts to prevent operational errors.   Perfect for medium factories, commercial shopping malls and multi-story building power cabinets, this m…
