Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V — so it handles high-fault-current scenarios downstream of a transformer or in a main distribution board without cascading upstream. ## Built-in accessories and trip configuration The TM240 thermal-magnetic trip unit is fixed — no interchangeable rating plugs — so the 200 A frame is the trip rating.","metaTitle":"Siemens 3VA1220-5GF42-0KH0 SENTRON MCCB, 200 A, 4-Pole, Line","metaDescription":"Siemens SENTRON 3VA1220-5GF42-0KH0 molded case circuit breaker, 200 A rated, 4-pole, line protection.
