What this order code delivers
The Siemens 3VA1163-5MH36-0BA0 is a 3-pole IEC molded-case circuit breaker on the 160 A frame, rated 63 A continuous with a TM120M thermal-magnetic trip unit configured for starter protection — meaning it coordinates with a contactor to handle motor start-up inrush without nuisance trips. The 'AM' designation means it ships without overload protection (the starter handles that), so this breaker provides only short-circuit and ground-fault protection with an adjustable instantaneous trip from 5 to 15 times In. Breaking capacity is 55 kA at 415 V AC (class M), which is enough for most industrial distribution panels behind a moderate-size transformer.
Integration notes
Clamp-type terminals accept copper or aluminum conductors — no lug kit needed for most panel builds. The undervoltage release (UVR) coil is 24 V DC; if the control voltage drops, the breaker trips, which is standard practice for emergency-stop or safety-related disconnect circuits. Mounts on a standard DIN rail or panel-mount via the 3VA1 accessory footprint.
