The Siemens 3VA1163-6MH32-0JH0 is a 3VA1 IEC frame 160 molded case circuit breaker with a 63 A rating and a 70 kA breaking capacity at 415 V (class H). It's a 3-pole unit configured for starter protection with a TM120M thermal-magnetic release, adjustable short-circuit pickup Ii from 5 to 15 x In. This variant ships without overload protection — it's a short-circuit-only device, so the upstream or downstream overload relay handles that job. The integrated shunt trip (STL) operates on 110-127 V DC or AC 50/60 Hz, and the breaker carries two HQ auxiliary switches plus one HQ trip alarm switch. A nut keeper kit is included for panel mounting.
Mounts on a DIN rail or panel plate via the included nut keeper kit. The 160 A frame size means it occupies a standard 3-pole MCCB footprint — plan for roughly 105 mm per pole width in the enclosure layout. The shunt trip coil draws from a separate control circuit; verify the control transformer is sized for the inrush if multiple breakers trip simultaneously.
