Product details

The C100N42EFM: Breaking capacity is 85 kA Icu at 240 V AC, 50 kA at 415 V, and 30 kA at 690 V — the N code (50 kA at 415 V) defines the standard interrupting rating for distribution duty. The electronic trip unit provides L (long-time overload) and I (instantaneous short-circuit) protection with a 20-minute thermal memory. Fixed-mount, front-connect design with a 70 mm pole pitch. IP40 enclosure, IK07 impact resistance. LCD display and local LED fault indication.

Sizing and application

Rated 1000 A continuous at 50 °C — the trip unit rating matches the frame size, so no derating is needed up to that ambient. Category B utilisation means it is fully selective with downstream breakers — the short-time delay (not present on this basic L/I trip unit) is not required for the instantaneous-only curve; coordination relies on the I²t characteristic.

Frequently asked questions

Where can I buy C100N42EFM and get a price?

The C100N42EFM is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the breaking capacity of C100N42EFM at 415 V?

The C100N42EFM has a breaking capacity of 50 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2.

What trip unit does C100N42EFM use?

It uses a MicroLogic 2.0 E electronic trip unit providing L (long-time overload) and I (instantaneous short-circuit) protection.
