Product details

The C40R32D250 is a Schneider Electric ComPacT NSX moulded-case circuit breaker in the NSX400R frame, rated 250 A at 40 °C with a MicroLogic 2.3 electronic trip unit.

The R breaking capacity code (200 kA at 415 V AC) places this MCCB in the top tier of the ComPacT NSX line for fault-current interruption. At 220/240 V and 440 V it also holds 200 kA Icu; at 500 V it drops to 80 kA, and at 690 V to 45 kA.

Trip unit and protection

The MicroLogic 2.3 provides L (long-time overload), So (short-time short-circuit with fixed delay), and I (instantaneous) protection curves. Local signalling includes a green flashing LED for ready state, red at 105 % Ir for overload, and orange at 90 % Ir for pre-alarm.

Mounts on a backplate in horizontal or vertical orientation, flat on the back. The 45 mm connection pitch and 6 accessory slots accommodate shunt trips, auxiliary contacts, and motor mechanisms. Front upside and downside connections simplify busbar or cable termination in a panel. IP40 enclosure protection and IK07 impact resistance suit indoor distribution boards.

Frequently asked questions

What is the breaking capacity of C40R32D250 at 415 V?
