Product details

The Schneider Electric C10W32D040 is a ComPacT NSX frame circuit breaker, 3-pole, rated 40 A at 40 °C with a MicroLogic 2.2 electronic trip unit. The MicroLogic 2.2 provides LSoI protection: long-time overload (L), short-time short-circuit with fixed delay (So), and instantaneous short-circuit (I). That matters for motor or transformer feeders where repeated inrush can nuisance-trip a thermal-magnetic breaker.

Deployment context

Mounts flat on a backplate in horizontal or vertical orientation. Front-facing connections on both upside and downside simplify bus-bar or cable routing in a panel.

Rated for 20,000 mechanical cycles and 20,000 electrical cycles at 440 V In/2, dropping to 5,000 cycles at 690 V In. That's typical for a molded-case breaker in distribution duty — not a switching device for frequent motor starts, but fine for infrequent load isolation and fault protection.

Frequently asked questions

What is the breaking capacity of C10W32D040?

100 kA Icu at 500 V, 525 V, and 690 V AC 50/60 Hz per IEC 60947-2. That is the highest breaking capacity in the NSX100 frame, suitable for high-fault industrial distribution.

What protection curves does the MicroLogic 2.2 trip unit provide?

L (long-time overload), So (short-time short-circuit with fixed delay), and I (instantaneous short-circuit). The electronic trip includes 20-minute thermal memory before and after tripping.

What compliance documentation is available for C10W32D040?

The breaker is certified to EN/IEC 60947-2 for isolation suitability. Standard documentation includes the manufacturer's declaration of conformity; specific RoHS, REACH, or UL documentation can be provided on request with the RFQ.
