The trip block is configured for starter protection (AM characteristic), meaning it coordinates with a contactor/overload pair rather than providing its own overload function; short-circuit pickup Ii is adjustable 5 to 15 times In. This order code includes a shunt trip (STL) release rated 12–30 V DC or 24 V AC 50/60 Hz, plus two HQ auxiliary switches for remote status indication. A nut keeper kit is factory-fitted, which simplifies panel mounting on busbar or backplate studs. The 63 A TM120M trip provides motor-starting inrush tolerance (AM curve) while the adjustable Ii (5–15× In) lets you fine-tune magnetic pickup to the branch load. The shunt trip coil draws from a separate 12–30 V DC or 24 V AC supply, so it can be wired to an emergency-stop relay or remote pushbutton without loading the breaker's own control circuit. The two HQ auxiliary switches change state with the main contacts, giving the PLC or annunciator a direct status signal.","metaTitle":"Siemens 3VA1163-6MH32-0HC0 Circuit Breaker, 70kA @ 415V, 63A","metaDescription":"Siemens 3VA1163-6MH32-0HC0 IEC frame 160 circuit breaker, 70kA breaking capacity @ 415V, 63A, with shunt trip and aux switches.
