Product details

The C10W46E040 is a Schneider Electric ComPacT NSX moulded-case circuit breaker rated 40 A at 40 °C, 4-pole, with a MicroLogic 6.2 E electronic trip unit. The 100 kA Icu at 690 V AC per IEC 60947-2 means it can safely interrupt fault currents up to that level on a 690 V line without upstream cascading — the HB2 breaking capacity code confirms that. The 6.2 E trip provides L (long-time overload), S (short-time short-circuit), I (instantaneous), and G (ground-fault) protection, plus an energy-meter function and LCD display for time-stamped event logs and power-quality data.

Selectivity and coordination

The electronic trip unit's LSI+G curves give the site engineer fine-grained selectivity with downstream breakers.

Four poles with neutral on the left. The 161 x 140 x 86 mm (H x W x D) footprint fits standard panel layouts.

Frequently asked questions

Who supplies C10W46E040 and how is it quoted for volume purchases?

C10W46E040 is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What is the closest pin-compatible alternative to C10W46E040 in this component family?

Within the ComPacT NSX family, a different trip-unit rating (e.g., a MicroLogic 2.2 or 5.2 E at 40 A) would share the same frame and footprint but change the protection curve and feature set — the physical mounting and connection pitch remain identical.
