Overload protection is set via the TM240 ATAM trip unit: In=500A, with an adjustable Ir from 350A to 500A. Short-circuit magnetic pickup Ii is adjustable from 5 to 10 times In, so you can dial in selectivity with downstream breakers without sacrificing speed on a hard fault. ## Panel Integration & Fit The 630A frame takes up the same footprint as other 3VA1 breakers in this class, so swap-in for a failed unit is straightforward — no re-drilling the backplate. The TM240 ATAM trip is thermal-magnetic, not electronic — no auxiliary power needed for the trip unit, and no nuisance tripping from harmonics on a VFD line. That's a plus for field-service techs who want a breaker that just works without programming.","metaTitle":"3VA1450-4EF42-0AA0-ZD00 Siemens 3VA1 630A Frame, 36kA @ 415V","metaDescription":"Siemens 3VA1450-4EF42-0AA0-ZD00 IEC circuit breaker, 630A frame, 36kA breaking capacity @ 415V, 4-pole, TM240 ATAM, In=500A, Ir=350-500A, Ii=5-10xIn.
