This variant is configured for starter protection: the TM120M trip provides short-circuit protection only (Ii adjustable 5–15 x In), with no overload protection element — the motor starter's own overload relay handles that. The nut keeper kit secures the breaker in the enclosure without loose hardware — saves time during panel build-out. The UVR coil draws from a 208–230 V AC control transformer; verify the control circuit is separately protected. Auxiliary switches HQ and the trip alarm switch share the same terminal layout — wire per the Siemens wiring diagram for the 3VA1 family.","metaTitle":"Siemens 3VA1163-5MH32-0DH0 Circuit Breaker, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5MH32-0DH0 IEC frame 160 MCCB, 3-pole, 63A, Icu=55kA @ 415V.
