Schneider Electric C12F6TM160B ComPacT NSXm160F 4P 160 A 36 kA TM-D Fixed Moulded Case Circuit Breaker

The C12F6TM160B is a 4-pole (3D, neutral unprotected) Schneider Electric ComPacT NSXm160F moulded case circuit breaker rated 160 A, with a TM-D thermal-magnetic trip unit and 36 kA breaking capacity (Icu) at 380/415 V AC. Rated operational voltage (Ue) is 440 V AC. The 108 x 137 x 80 mm frame adds a switched, unprotected neutral pole for 3-phase-plus-neutral distribution circuits.

Selection Notes

At 160 A the C12F6TM160B runs the TM-D trip unit at the top of its 0.7...1 x In adjustment band, so the thermal setting can be dialled back if the downstream feeder is sized for less than the full frame current. The 3D pole configuration switches the neutral without protecting it — pick a 4P 4D device elsewhere in the NSX range if the neutral itself needs overload protection. Against the 125 A sibling in the same 36 kA/4P frame, this 160 A unit is the choice when the feeder cable is sized for the higher current.
