That 55kA interrupting rating means it clears high-fault currents on a 415 V line without cascading upstream — sized for main or large feeder duty in an industrial panel. Overload protection is adjustable via the TM240 thermal-magnetic trip unit: Ir from 44A to 63A, short-circuit pickup Ii from 5 to 10 x In. The shunt trip (STL) operates on 12–30 V DC or 24 V AC, so it integrates into a 24 V control scheme for remote tripping. ## Deployment context The auxiliary and trip-alarm switches plug into the breaker's accessory slot — no separate wiring compartment needed. In a water/wastewater lift station, the 55 kA SCCR at 415 V gives headroom for coordination with downstream feeders; the shunt trip lets a PLC or level controller drop the breaker on high-wet-well or H2S alarm without waiting for a manual trip.","metaTitle":"Siemens 3VA1163-5EF32-0HH0 Circuit Breaker, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5EF32-0HH0 IEC frame 160 MCCB, 3-pole, 63A, Icu=55kA @ 415V.
