It is configured for starter protection — meaning the TM release provides short-circuit protection only, with no overload protection function built in. The adjustable instantaneous trip (Ii) range is 5 to 15 times In (315 A to 945 A), sized for motor branch circuits where a separate overload relay handles the thermal curve. ## Integrated accessories and panel fit Mounts on standard DIN rail in the 3VA1 footprint; the frame 160 form factor is common across the 3VA series, so panel cutouts and busbar layouts transfer if you swap between frame sizes.","metaTitle":"Siemens 3VA1163-6MH32-0KC0 Circuit Breaker, 63A, 70kA @ 415V","metaDescription":"Siemens 3VA1163-6MH32-0KC0 IEC frame 160 circuit breaker, 63A, 70kA breaking capacity @ 415V.
