It is configured for starter protection using a TM120M trip unit — magnetic-only, no overload function — so the overload protection is handled upstream by a separate motor starter or thermal relay. The short-circuit release is adjustable from 5 to 15 times In, giving you flexibility to coordinate with downstream components. The 63 A continuous rating matches a 37 kW motor at 400 V (roughly 60 A FLA) or a 45 kW motor if the service factor allows. The magnetic-only TM120M means this breaker does not provide thermal overload protection; it's intended for motor branch circuits where a separate overload relay handles the thermal curve. The undervoltage release (UVR) at 24 V DC will trip the breaker if control voltage is lost — common in emergency-stop chains or safety circuits where loss of power must open the motor circuit.","metaTitle":"Siemens 3VA1163-6MH36-0BC0 Circuit Breaker, 63A, 70kA @ 415V","metaDescription":"Siemens 3VA1163-6MH36-0BC0 IEC frame 160 MCCB, 63A, 70kA breaking capacity at 415V AC.

The frame, breaking capacity, and terminal style are shared, so the physical fit and SCCR remain the same; the choice depends on whether you need integral overload protection."},{"question":"What compliance documentation does this brand provide for 3VA1163-6MH36-0BC0?","answer":"Siemens 3VA series breakers carry IEC 60947-2 certification, and typically UL/CSA listings for the North American market.

Specific certification marks for this order code should be verified against the product label or factory certificate."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1163-6MH36-0BC0","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/3VA1163-6MH36-0BC0 when reusing this data.
