It's configured for motor starter protection using a TM120M thermal-magnetic release with adjustable short-circuit pickup (Ii = 5–15 × In), but notably without integrated overload protection — that's handled separately by the starter. The unit includes a shunt trip (STL) for 110–127 V DC or AC 50/60 Hz remote tripping, plus two HQ auxiliary switches for status feedback. All connections are via clamp terminals. The class M designation indicates a medium breaking capacity tier within the 3VA1 family, suitable for most industrial distribution panels where fault currents are moderate. The TM120M release provides thermal-magnetic protection for motor circuits: the thermal element tracks overload heating (without tripping on starting inrush), while the magnetic element handles short circuits. The adjustable Ii range (5–15 × In) lets you set the instantaneous trip point between 315 A and 945 A, matching the motor's locked-rotor current. The shunt trip (STL) allows remote or emergency-stop tripping by applying 110–127 V AC/DC to the coil. The two HQ auxiliary switches provide normally open/closed contacts for PLC or status lamp feedback — HQ denotes high-quantity (high-reliability) contacts rated for signal-level switching. ## Deployment Context The clamp terminals accept copper or aluminum conductors up to the rated cross-section for the frame size — no special lug kits needed for most panel builds. It's sized for motor control centers (MCCs), distribution boards, or as a feeder breaker in a sub-panel feeding motor starters.","metaTitle":"Siemens 3VA1163-5MH36-0JC0 Circuit Breaker, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5MH36-0JC0 IEC frame 160 circuit breaker, 3-pole, 63A, Icu=55kA @ 415V, starter protection TM120M, shunt trip, 2 aux switches.

If the available fault current at your panel's point of installation is below that, this breaker is a suitable choice without needing a current-limiting upstream device."},{"question":"Does this breaker include overload protection for the motor?","answer":"No. The description explicitly states 'without overload protection.' Overload protection must be provided by a separate thermal overload relay or motor protection circuit breaker in the starter assembly.
