The Schneider Electric C100L4FM is a basic frame from the ComPacT NS630b...1600 new generation range — a 4-pole, fixed-mount, manually operated air circuit breaker frame rated 1000 A at 50 °C. It ships without a control unit (protection relay), so the buyer selects and installs the appropriate trip unit separately. This is the high-interrupting 'L' variant: 150 kA Icu at 380/415 V AC, 130 kA at 440 V, and 100 kA at 500/525 V, all per IEC 60947-2.
The rated short-time withstand current (Icw) is 19.2 kA for 1 second, which matters for selective coordination: downstream breakers can clear a fault while this frame holds closed long enough for the upstream protection to stay in.
Fixed backplate mounting with a 70 mm connection pitch. Dimensions: 224 mm high, 280 mm wide, 147 mm deep. IP40 front face protection (IK07 impact resistance) — suitable for enclosed panel installation where the front face is operator-accessible. The neutral pole is positioned on the left. Class II insulation on the front face means no protective earth connection is required on the operator side.
Certified to IEC 60947-2. Electrical durability: 2000 cycles at rated current (690 V AC), 3000 cycles at half-rated current. Mechanical durability: 10,000 cycles.
