It ships with a TM120M thermal-magnetic trip unit configured for starter protection: no overload protection (the starter handles that), just short-circuit protection adjustable from 5 to 15 times In (315–945 A magnetic pickup). The undervoltage release (UVR) operates on 24 V DC — if that control voltage drops, the breaker trips instantly, which is standard for emergency-stop or safety-hold circuits. Auxiliary switching comes as two HQ form-C contacts plus one HQ trip-alarm switch, all wired via clamp terminals. The UVR coil draw is modest; verify your 24 V DC supply can hold the coil continuously — typical hold current for this class is under 2 A, but check the coil rating on the nameplate. Clamp terminals accept copper or aluminum conductors; torque to the values stamped on the breaker face. The UVR and auxiliary switches are factory-installed — no field-kit wiring needed.","metaTitle":"Siemens 3VA1163-5MH36-0BH0 Circuit Breaker, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5MH36-0BH0 IEC frame 160 MCCB, 63A, Icu=55kA @ 415V, starter protection TM120M, UVR 24V DC, 2 aux switches.

The closest functional sibling would be a 3VA1 breaker with the same frame, poles, and breaking capacity but without the factory UVR or auxiliary switches — those are field-addable kits. No single pin-compatible drop-in exists because the UVR and auxiliary switch configuration is factory-locked to this order code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1163-5MH36-0BH0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA1163-5MH36-0BH0 when reusing this data.
