It's configured for starter protection with a TM120M thermal-magnetic trip unit, rated 63 A, but note: this variant provides short-circuit protection only — no overload protection. Two HQ auxiliary switches give status feedback to the control system. This breaker uses clamp (lug) connections, so it lands on busbars or cable lugs in a distribution panel or motor starter bucket. The 3VA1 frame is DIN-rail mountable, but at 63 A and with shunt trip wiring, plan for finger-safe gland plates and enough bend radius on the control wires to the STL terminals. Lifecycle stage is current — Siemens still lists this as an active catalog number, so it's not on LTB or EOL notice. That means it's specifiable into new BOMs without a PCN watch.","metaTitle":"Siemens 3VA1163-6MH36-0HC0 Circuit Breaker, 70 kA @ 415 V, 6","metaDescription":"Siemens 3VA1163-6MH36-0HC0 IEC frame 160 circuit breaker, 70 kA breaking capacity @ 415 V, 63 A, starter protection TM120M, shunt trip.

The TM120M trip unit is configured for starter protection without overload, so you need a separate overload relay upstream or in the starter assembly."},{"question":"Where can I buy 3VA1163-6MH36-0HC0 and how is it quoted?","answer":"We source this part to order against an RFQ through our independent distribution network.
