This is a starter-protection variant (TM120M release) configured for motor branch circuits: it provides short-circuit protection with an adjustable instantaneous trip Ii=5...15 x In, but omits the overload protection element — meaning it relies on a separate overload relay upstream or downstream for thermal motor protection. Clamp-type terminals accept copper or aluminium conductors up to the frame's rated cross-section.","metaTitle":"Siemens 3VA1163-5MH36-0AE0 Circuit Breaker, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5MH36-0AE0 IEC frame 160 MCCB, 63A, 55kA breaking capacity at 415V.

This is the class M (medium) breaking capacity in the 3VA1 range."},{"question":"Why does this breaker have no overload protection?","answer":"This is a starter-protection variant (TM120M release) designed for motor branch circuits where a separate overload relay provides the thermal protection. The breaker handles short-circuit protection only, with an adjustable instantaneous trip set between 5 and 15 times the rated current (In=63 A)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1163-5MH36-0AE0","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/3VA1163-5MH36-0AE0 when reusing this data.
