Overload protection (Ir) is adjustable from 175 A to 250 A via the ATAM dial, so a single breaker frame covers a range of feeder sizes — a 200 A motor branch today, a 225 A feeder next quarter. That band lets the panel builder tune coordination with downstream branch breakers without swapping trip units. ## Integrated shunt trip and neutral protection The factory-fitted shunt trip (STL) operates on 110-127 V DC or AC 50/60 Hz — a remote-trip coil for emergency-stop circuits or supervisory control. The N-conductor protection is set at 100%, so the neutral pole tracks the phase poles.","metaTitle":"3VA1225-6GF42-0JA0 Siemens 3VA1 IEC Frame 250, 70kA @ 415V","metaDescription":"Siemens 3VA1225-6GF42-0JA0 circuit breaker, IEC frame 250, class H Icu=70kA @ 415V, 4-pole, TM240, In=250A, shunt trip.
