This makes it a single-device solution for both overcurrent and ground-fault protection in a distribution panelboard. ## Breaking capacity across common voltage levels The C25F44V160 delivers 85 kA Icu at 220/240 V AC, 36 kA at 380/415 V AC, 35 kA at 440 V, 30 kA at 500 V, 22 kA at 525 V, and 8 kA at 660/690 V AC, all per IEC 60947-2. Under UL 60947-4-1 it is rated 85 kA at 240 V, 35 kA at 480 V, and 15 kA at 600 V AC. The 4-pole unit has neutral on the left. IP40 enclosure protection suits indoor panel installation; IK07 impact resistance handles typical cabinet handling. ## Trip unit and protection characteristics The MicroLogic 4.2 electronic trip unit includes thermal memory with a 20-minute retention before and after tripping — this prevents nuisance reclosure on a hot conductor. Local signalling includes a flashing green LED for ready-to-operate, red LED at 105 % Ir for overload, and orange LED at 90 % Ir for pre-alarm. The toggle control type provides manual on/off with the IΔn rotary switch for earth-leakage testing. Electrical durability is 20,000 cycles at 440 V In/2 and 10,000 cycles at 440 V In; mechanical durability is 20,000 cycles.","metaTitle":"Schneider C25F44V160 ComPacT NSX 160A MCCB, 85kA Icu","metaDescription":"Schneider Electric C25F44V160 ComPacT NSX 160A MCCB with MicroLogic 4.2 electronic trip unit. 85 kA Icu at 240 V AC, 36 kA at 415 V.
