It is configured for starter protection with a TM120M thermal-magnetic release (AM characteristic) and adjustable short-circuit protection Ii=5...15 x In. The TM120M trip unit provides thermal-magnetic overload and short-circuit protection; the AM characteristic means the magnetic trip is adjustable from 5 to 15 times the rated current (315 A to 945 A), letting you coordinate with downstream motor starters or branch feeders. The 63 A continuous rating matches a 63 A bus or feeder tap. The included nut keeper kit secures the busbar connections without loose hardware. The two HQ auxiliary switches and one HQ trip alarm switch provide remote status indication — wire them into the PLC digital input bank for breaker position and trip feedback.","metaTitle":"Siemens 3VA1163-5MH32-0AH0 Circuit Breaker, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5MH32-0AH0 IEC 3VA1 frame 160 circuit breaker, 63A, 55kA breaking capacity at 415V.
