The TM120M thermal-magnetic release provides starter protection, but note the description flags it as supplied without overload protection; the TM120M here is configured for short-circuit protection only, adjustable Ii = 5...15 x In. The integrated shunt trip (STL) operates on 12-30 V DC or 24 V AC, letting a safety relay or remote E-stop drop the breaker without running control power through the main bus. Mounts on standard DIN rail inside an enclosure. The nut keeper kit (included per the order code suffix) retains the terminal screws during high-vibration environments — a detail that saves a re-torque pass during commissioning. The shunt trip coil draws from a separate control supply; verify the 12-30 V DC range covers your safety circuit's nominal voltage with margin for brownout.","metaTitle":"Siemens 3VA1163-6MH32-0HA0 Circuit Breaker, 63A, 70kA @ 415V","metaDescription":"Siemens 3VA1163-6MH32-0HA0 IEC frame 160, 3-pole, 63A, breaking capacity 70kA @ 415V, shunt trip 12-30V DC/24V AC.

Submit an RFQ for current pricing and availability — figures are confirmed at quote time, not on a static listing."},{"question":"What does the 70 kA breaking capacity at 415 V mean for my panel?","answer":"It means the breaker can safely interrupt a fault current up to 70,000 A at 415 V AC without failing. This is a class H rating, suitable for high-fault installations where the available short-circuit current exceeds what standard (class N or S) breakers can handle. It gives selectivity headroom upstream."},{"question":"Does this breaker include overload protection?","answer":"No. The description states it is supplied without overload protection; the TM120M release provides short-circuit protection only, with adjustable instantaneous trip Ii = 5...15 x In. Overload protection must be provided separately, typically by a motor starter or thermal overload relay upstream."},{"question":"What compliance documentation is available for 3VA1163-6MH32-0HA0?","answer":"Siemens provides RoHS and REACH declarations, plus IEC 60947-2 test certificates for the 3VA1 series.
