The short-circuit trip threshold is adjustable from 5 to 15 times In, letting you dial in coordination with downstream contactors and overload relays. ## Integration notes for panel builders Clamp connections accept copper conductors — strip length and torque values follow the manufacturer's published terminal data. The shunt trip and auxiliary switch wiring share the same terminal compartment; verify free-wheel diode polarity on the STL coil if driving it from a DC source. Because this breaker provides short-circuit protection only (no overload protection in the TM120M release), a separate overload relay must be wired downstream for motor branch circuits. The Ii adjustment range (5-15 x In) lets the installer set the magnetic trip to ride through motor start without nuisance tripping.","metaTitle":"Siemens 3VA1163-6MH36-0HH0 Circuit Breaker, 63 A, 70 kA @ 41","metaDescription":"Siemens 3VA1163-6MH36-0HH0 IEC frame 160 circuit breaker, 63 A, 70 kA breaking capacity @ 415 V, shunt trip, 2 aux switches.
