The Siemens 3VA1220-5MH32-0KC0 is a 3-pole molded case circuit breaker from the 3VA1 IEC frame 250 series, rated 200 A continuous. Its headline breaking capacity is 55 kA at 415 V AC — that's the Icu (ultimate short-circuit capacity) for class M, meaning it can safely interrupt a fault up to that level and still be operable afterward. For a 415 V distribution board or motor control center, that's enough headroom for most industrial service entrances without cascading upstream breakers. The TM120M thermal-magnetic trip unit is set for starter protection — the magnetic pickup is adjustable from 6 to 14 times In. The shunt trip (STL) operates on 220-250 V DC or 208-277 V AC, with two HQ auxiliary switches for status feedback.
