Schneider Electric C10F42D040 is a ComPacT NSX100F molded case circuit breaker designed for low-voltage AC power distribution, providing dependable protection for feeders and equipment in industrial and commercial installations. This fixed-mount, 4-pole unit features a MicroLogic 2.2 electronic trip unit with a 40 A rated current (at 40°C) and protection functions for long-time overload, short-time short-circuit (fixed delay), and instantaneous short-circuit events. Rated for operation up to 690 V AC (50/60 Hz), it delivers high interrupting performance with 36 kA breaking capacity at 380/415 V AC (IEC 60947-2), along with suitability for isolation. The breaker supports adjustable long-time pickup (18–40 A) and adjustable short-time pickup (1.5–10 x Ir), with fixed instantaneous pickup at 600 A, and includes LED status indication for readiness and overload thresholds. With IP40 front protection, durable mechanical and electrical endurance, and a compact 140 mm x 161 mm x 86 mm form factor, the C10F42D040 is well suited for switchboards and control panels requiring reliable 4-pole protection and consistent trip performance.
