This variant is configured for starter protection with a TM120M thermal-magnetic trip unit. The thermal element is sized for motor starting inrush (the 'M' designation), so it won't nuisance-trip on a 6x locked-rotor current during a start sequence. The magnetic short-circuit pickup is adjustable from 5 to 15 times In (315 A to 945 A), letting you coordinate with downstream contactors and overload relays. Note: this breaker provides short-circuit protection only — there is no integral overload protection, so a separate overload relay (e.g., Siemens 3RU2) must be wired downstream for motor thermal protection. The clamp-type terminals accept copper or aluminum conductors — strip length and torque values follow the manufacturer's published tightening schedule for the 160 A frame. Two factory-installed auxiliary switches (HP type) are included for remote status indication; they share the breaker's operating mechanism and require no separate power supply.","metaTitle":"Siemens 3VA1163-5MH36-0AB0 Circuit Breaker, 55kA @ 415V, 63A","metaDescription":"Siemens 3VA1163-5MH36-0AB0 IEC frame 160 MCCB, breaking capacity class M, Icu=55kA @ 415V, 3-pole, 63A, starter protection TM120M.
