It ships with a TM240 thermal-magnetic trip unit set for 200 A continuous, with overload protection adjustable from 140 A to 200 A and short-circuit pickup adjustable from 5 to 10 times In. The built-in shunt trip (STL) operates on 220–250 V DC or 208–277 V AC — a common coil voltage for remote-trip integration in industrial panels. ## Deployment context Panel-mounted in a standard IEC enclosure, the 3VA1 frame accepts plug-in or fixed connections and integrates with Siemens ALPHA or SIVACON busbar systems. The 100% neutral conductor protection and nut keeper kit simplify installation in switchboards where phase and neutral need equal thermal protection.","metaTitle":"Siemens 3VA1220-4GF42-0KA0 Circuit Breaker, 200A, 36kA @ 415","metaDescription":"Siemens 3VA1220-4GF42-0KA0 IEC frame 250 circuit breaker, 200A, 36kA breaking capacity at 415V.
