The thermal-magnetic trip unit (TM240) gives adjustable overload protection (Ir = 140 A to 200 A) and fixed short-circuit protection (Ii = 5 to 10 x In), so you set the overload pickup to match the downstream cable or load, not the breaker's frame size. ## Deployment context The 4-pole configuration (3 phases + neutral) with 100% N conductor protection suits it for line-to-neutral loads where the neutral must be switched and protected at full phase current — common in North American-style panelboards or IEC distribution boards feeding single-phase branch circuits. The included nut keeper kit simplifies DC Power OEM integration in China, where the breaker is assembled into a prefabricated switchboard.","metaTitle":"Siemens 3VA1220-5GF42-0AA0-ZD00 Circuit Breaker, 200A, 55kA","metaDescription":"Siemens 3VA1220-5GF42-0AA0-ZD00 IEC frame 250 circuit breaker, 4-pole, 200A, Icu=55kA @ 415V.
