The TM240 trip offers adjustable overload protection (Ir) from 175 A to 250 A, so you set the continuous current limit to match the downstream load — a motor feeder or a transformer primary, for instance. The 100% N-conductor protection means the neutral pole is fully rated, not reduced — critical for 4-wire systems with harmonic content where the neutral carries sustained current. It drops the breaker open when supply voltage falls below the dropout threshold, preventing automatic reclosure on a brownout or phase loss — standard practice for motor loads that must not restart unattended. For BOM-line commitment, the key ratings — 55 kA @ 415 V, 250 A frame, TM240 trip with adjustable Ir and Ii, and the 208–230 V UVR — are all confirmed on the order code.","metaTitle":"Siemens 3VA1225-5GF42-0DA0 Circuit Breaker, 55kA @ 415V","metaDescription":"Siemens 3VA1225-5GF42-0DA0 IEC frame 250 MCCB, 55kA breaking capacity @ 415V AC, 4-pole, TM240 thermal-magnetic trip, 250A.
