The TM240 thermal-magnetic trip unit provides adjustable overload protection (Ir = 140 A to 200 A) and fixed short-circuit protection (Ii = 5 to 10 × In, so 1000 to 2000 A). The 100% N-conductor protection means the neutral pole is fully rated, not just a switched neutral — necessary for 4-wire systems with harmonic content where neutral current can approach phase current. This variant includes a nut keeper kit and is configured for DC Power OEM applications in China. The nut keeper secures the line/load lug fasteners against vibration in transport or high-vibration environments like inverter cabinets.","metaTitle":"Siemens 3VA1220-6GF42-0AA0-ZD00 Circuit Breaker, 70kA @ 415V","metaDescription":"Siemens 3VA1220-6GF42-0AA0-ZD00 IEC frame 250 circuit breaker, 70kA breaking capacity @ 415V, 4-pole, TM240 thermal-magnetic trip, In=200A.
