Product details

The C11B44V100B is a Schneider Electric ComPacT NSXm moulded-case circuit breaker rated 100 A at 40 °C with a 4-pole configuration (4P). The electronic MicroLogic 4.1 trip unit gives adjustable thermal and magnetic protection curves, plus integrated earth-leakage protection with selectable sensitivity from 30 mA to 5 A for class A and class AC residual currents. This breaker is designed for distribution applications (not motor starting — it is utilisation category A). It mounts on a backplate, accepts front-connect compression lugs or busbars, and occupies 12 module pitches at 9 mm each, so it needs 108 mm of panel width.

The breaker complies with EN/IEC 60947-2, the standard for low-voltage switchgear and controlgear. Overvoltage category IV suits it for installation at the origin of the installation (utility entrance). The IK07 impact rating (per IEC 62262) means it withstands a 2 J impact — enough for panel handling but not for exposed outdoor use.

Frequently asked questions

Where can I buy C11B44V100B and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time.

What is C11B44V100B's breaking capacity?

The breaking capacity is 25 kA at 415 V AC, performance level B per IEC 60947-2.

What trip unit does C11B44V100B use?

It uses an electronic MicroLogic 4.1 trip unit with integrated earth-leakage protection. Earth-leakage sensitivity is selectable from 30 mA to 5 A for both class A and class AC residual currents.

What compliance documentation does this brand provide for C11B44V100B?

The breaker is certified to EN/IEC 60947-2. It carries an IP40 protection rating per IEC 60529 and an IK07 impact rating per IEC 62262. Pollution degree 3 per IEC 60664-1 and overvoltage category IV are specified.
