Product details

What this breaker is

The Schneider Electric C100H45EFM is a ComPacT NS new generation 4-pole molded-case circuit breaker rated 1000 A at 50 °C, fitted with a MicroLogic 5.0 E electronic trip unit. It belongs to the ComPacT NS630b...1600 new generation range and is designed for distribution applications per EN/IEC 60947-2.

The MicroLogic 5.0 E provides L (long-time overload), S (short-time short-circuit), and I (instantaneous) protection, plus energy metering for load profiling. Breaking capacity is 85 kA Icu at 220/240 V AC, 70 kA at 380/415 V, and 42 kA at 660/690 V. The 20-minute thermal memory prevents nuisance re-trip on hot restart after a momentary overload.

Fixed-mount design on a backplate with front connections both top and bottom. The 280 mm width, 327 mm height, and 147 mm depth define the panel cutout and clearance — 70 mm connection pitch for busbar or cable landing. IP40 enclosure protection keeps out tools and fingers; IK07 impact rating for panel-door mounting.

Frequently asked questions

What is the breaking capacity of C100H45EFM at 415 V?
