YBRM5E-250 Molded Case Circuit Breaker

YBRM5E - 250 series electronic molded case circuit breaker is used in industrial and building power distribution systems at an altitude of 2000 meters and below, with rated insulation voltage of AC800V, 50Hz/60Hz, rated operating voltage of 690V and below, and rated current ≤ 250A. The breaking capacity is divided into L, M, and H types, which can provide short circuit and overload protection for cables, electrical equipment, electric motors, etc.It has a rated operating voltage of AC400/690V, a rated insulation voltage of 1000V, and a rated shock withstand voltage of 8kV. The rated current is 100A, 250A, etc., and the short-circuit breaking capacity is 55kA for N-type, 100kA for H-type, and 150kA for S-type at 400V. Ics at 690V, 25kA for Type N, 35kA for Type H, and 65kA for Type S. The mechanical life is 30000 times, and the 400V electrical life is 15000 times. The long-delay trip current setting for the thermomagnetic trip and magnetic trippers is (0.4 - 1.0)×In, the thermal magneti…
