Product details

The C256TM160 is a TM-D thermal-magnetic trip unit for the Schneider Electric ComPacT NSX250 range, rated 160 A at 40 °C and 690 V AC. It provides LI protection — thermal overload (L) and magnetic short-circuit (I) — with a fixed instantaneous pick-up of 1250 A.

The 1250 A instantaneous magnetic trip (Ii) means the unit will clear a short-circuit fault at roughly 7.8 x In without delay — this is a fixed value, not adjustable, so verify it coordinates with downstream devices. The 690 V AC rated operational voltage covers most 400 V and 480 V distribution systems with margin.

Frequently asked questions
