The adjustable instantaneous trip (Ii) range of 5 to 15 x In lets you dial in the magnetic pickup to coordinate with downstream motor starters or feeder circuits. The integrated undervoltage release (UVR) operates on 120-127 V AC 50/60 Hz, so if the control voltage drops, the breaker trips — a standard requirement for safety circuits that need to drop power on loss of control supply. Two HQ auxiliary switches and one HQ trip alarm switch provide status feedback for the PLC or DCS, letting the control system know whether the breaker is open, closed, or tripped on fault. ## Deployment context The 3-pole configuration suits three-phase motor loads — conveyors, pumps, fans — typical in continuous-process lines.","metaTitle":"Siemens 3VA1163-5MH32-0CH0 Circuit Breaker, 55kA @ 415V, 63A","metaDescription":"Siemens 3VA1163-5MH32-0CH0 IEC frame 160 MCCB, 55kA Icu @ 415V, 63A TM120M, UVR 120-127V AC.
