Product details

The Siemens 3VA1163-6MH32-0KA0 is a 3-pole IEC frame 160 molded case circuit breaker rated 63 A, with a 70 kA breaking capacity at 415 V (class H). The TM120M thermal-magnetic trip unit provides starter protection (motor branch circuit), with adjustable short-circuit pickup Ii = 5...15 x In. Note the description explicitly states 'without overload protection' — this unit is configured for short-circuit protection only, relying on a separate overload relay for the motor.

Deployment and integration

The integrated shunt trip (STL) operates on 220-250 V DC or 208-277 V AC, allowing remote tripping from an E-stop or PLC output.
