Uimp is 8 kV, so it sits comfortably in switchboards where impulse withstand is part of the coordination study rather than a hand-waved figure. Electrical endurance is rated at 7000 cycle, 60 cycles per hour, and mechanical endurance at 20000 cycle, 120 cycles per hour. For a feeder breaker that mostly sits closed, electrical cycle life is what governs; for a motor-starter isolation duty or any scheme where the breaker is racked in and out regularly, the 120 cycles-per-hour mechanical figure is the one that caps the maintenance interval. ## Panel fit Overall dimensions run roughly 20.5 cm tall by 14 cm wide by 10.35 cm deep. That footprint is the real number for a panel-builder working out DIN or cubicle cut-out — the shipping mass on the carton is not what you plan mounting around, and the breaker itself sits in the 5.1 Kg class.","metaTitle":"ABB 1SDA054381R1 T5V 400 TMAX, 400 A 3P","metaDescription":"ABB 1SDA054381R1 T5V 400 TMAX molded-case circuit breaker, 400 A frame, 3 poles, 8 kV Uimp.
