Siemens 3VM1 IEC frame 160, breaking capacity class M, 3-pole circuit breaker, Icu=55kA @ 415V, line protection TM220 ATFM, In=125A, overload protection Ir=88-125A, short-circuit protection Ii=10 x In, terminal connection.
Mounts in a standard 3-pole IEC frame 160 footprint on a DIN rail or panel-mount base inside a switchboard or enclosed MCC bucket. Terminal connections accept copper or aluminum conductors sized for 125 A continuous; the line-side lugs land on a busbar or cable feeder, load-side lugs feed the downstream tap.
Icu = 55 kA at 415 V AC, which is the breaking capacity class M rating for the 3VM1 IEC frame 160 platform.
It uses a TM220 ATFM thermal-magnetic trip unit with fixed short-circuit pickup Ii = 10 × In and adjustable overload protection Ir from 88 A to 125 A.
