The Schneider Electric C100H3FM is a basic frame from the ComPacT NS630b...1600 new generation range — a 3-pole, fixed-mount, manually operated air circuit breaker frame rated 1000 A at 50 °C. It ships without a protection control unit, so you select and install the trip unit separately to match your distribution or generator protection scheme. The frame alone delivers 70 kA Icu at 380/415 V AC and 85 kA at 220/240 V AC per IEC 60947-2, which means it can safely interrupt fault currents up to those levels without upstream cascading. The short-time withstand (Icw) is 19.2 kA for 1 second, supporting selectivity coordination downstream. Mounts on a backplate with 70 mm connection pitch.
The Icw of 19.2 kA for 1 second is the short-time withstand: it lets downstream breakers clear a fault before this frame trips, enabling selective coordination. IP40 front face and IK07 impact resistance suit it for enclosed switchgear.
Fixed mounting on a backplate with 70 mm connection pitch — standard for switchboard busbar systems. The frame is manually operated with no integral protection; the trip unit is ordered separately. Overvoltage category III covers fixed-installation distribution panels. Electrical endurance is 2000 cycles at In, 690 V AC, and 5000 cycles at In, 440 V AC; mechanical endurance is 10,000 cycles. Storage temperature range -50 to 85 °C, operating -25 to 70 °C. Class II insulation on the front face means no protective earth connection needed on the operator side.
