It ships without overload protection (the TM120M provides short-circuit protection only), so it pairs with an external overload relay for motor starting duty. ## Built-in accessories and control wiring This variant comes factory-fitted with an undervoltage release (UVR) coil at 24 V DC, two HQ auxiliary switches, and one HQ trip alarm switch. The auxiliary switches give status feedback back to a PLC or panel lamp — one for the main contact position, one for the trip alarm.","metaTitle":"Siemens 3VA1163-6MH32-0BH0 Circuit Breaker, 70kA @ 415V, 63A","metaDescription":"Siemens 3VA1163-6MH32-0BH0 IEC frame 160 circuit breaker, 70kA breaking capacity @ 415V, 63A, with UVR 24V DC and aux switches.
