The C100L32AFM is a fixed-mount, manually operated ComPacT NS new generation circuit breaker from Schneider Electric, part of the NS630b...1600 range. It carries a MicroLogic 2.0 A electronic trip unit rated 1000 A at 50 °C, with L (long-time overload) and I (instantaneous short-circuit) protection curves. The 3P fixed form factor bolts to a backplate with a 70 mm connection pitch and front-facing terminals, so it fits standard switchboard busbar layouts without adapters. The electronic trip unit includes a 20-minute thermal memory, which prevents nuisance reclosing after a sustained overload by retaining the thermal model of the conductors. The LCD display and ammeter measurement give local readout of load current without a separate panel meter. Four red LEDs signal fault type; one yellow LED indicates overload pre-alarm.
Mounts fixed to a backplate inside a distribution switchboard or panel enclosure. The 327 mm height, 210 mm width, and 147 mm depth fit standard cubicle compartments; the 70 mm connection pitch matches common busbar drilling patterns. Front-side upside and downside connections simplify busbar routing and cable termination.
Electrical durability and operating limits
Rated for 10,000 mechanical cycles and 2,000 electrical cycles at full rated current (1000 A at 690 V), with higher cycle counts at reduced loads — 3,000 cycles at In/2 at 690 V, 3,000 cycles at In at 440 V, and 4,000 cycles at In/2 at 440 V. Ambient relative humidity range 0–95 %.
