The thermal-magnetic trip unit is a TM220 (ATFM type), with the continuous current rating In set at 25 A and the overload protection band Ir adjustable from 18 A to 25 A, giving the panel builder a ±28 % range to match the downstream load without swapping the breaker body. ## Short-circuit protection and selectivity The instantaneous short-circuit pickup Ii is fixed at 12.8 × In — that is 320 A for the 25 A rating. This fixed multiple means the breaker coordinates predictably with downstream branch devices: a 320 A magnetic threshold clears bolted faults fast while riding through motor inrush and transformer energization. Terminal connection type is standard screw-clamp, sized for the 160 A frame lugs.","metaTitle":"Siemens 3VM1125-5EE46-0AA2 Circuit Breaker, 55kA @ 415V, 25A","metaDescription":"Siemens 3VM1125-5EE46-0AA2 IEC frame 160 circuit breaker, 55kA breaking capacity @ 415V, 4-pole, TM220 thermal-magnetic trip, In=25A.
