Innovative YBRM5E - 630 Series Circuit Breaker

YBRM5E - 630 series electronic molded case circuit breaker is used in industrial and building power distribution systems at an altitude of 2000 meters and below, with an insulation voltage of AC800V, 50Hz/60Hz, a rated operating voltage of 690V and below, and a rated current of ≤630A. The breaking capacity is divided into types L, M, and H, which can protect cables, electrical equipment, and electric motors from short circuit and overload damage. Rated operating voltage AC400/690V, rated insulation voltage 1000V, rated shock withstand voltage 8kV. The rated current is 250A, 630A, etc., and the short-circuit breaking capacity is 400V, the ICU under 400V, N-type 55kA, H-type 100kA, and S-type 150kA; Ics at 690V, N-type 35kA, H-type 50kA, S-type 65kA. Mechanical life 20000 times, 400V electrical life 10000 times.The long-delay trip current setting for thermal magnetic and magnetic trippers is (0.4 - 1.0)×In, 20% instantaneous ×In±20% for thermal magnetic trippers, and 12×In±20% for magnet…
