Product details

The C40W46E400 is a ComPacT NSX molded case circuit breaker (MCCB) rated 400 A at 40 °C, with a MicroLogic 6.3 E electronic trip unit providing L (long-time overload), S (short-time short-circuit), I (instantaneous), and G (ground fault) protection. The 4-pole (4P) configuration with neutral on the left suits three-phase plus neutral distribution panels, and the 185 mm width and 255 mm height fit standard backplate mounting patterns.

Trip unit and metering capability

The LCD display and energy meter function give real-time demand current, power quality, and time-stamped event logs, which a panel builder can use for load profiling without adding a separate power monitor.

The IK07 impact rating (IEC 62262) handles accidental tool drops during commissioning.

Frequently asked questions

What is C40W46E400's breaking capacity?

100 kA Icu at 690 V AC 50/60 Hz per IEC 60947-2, with the same rating at 500 V and 525 V AC.

What protection functions does the MicroLogic 6.3 E trip unit provide?

L (long-time overload), S (short-time short-circuit), I (instantaneous short-circuit), and G (ground fault) — four protection curves in one electronic trip unit.

Where can I buy C40W46E400?

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

What compliance documentation is available for C40W46E400?

The breaker is certified to EN/IEC 60947-2, carries pollution degree 3 and overvoltage category III ratings, and is designed for distribution applications. Specific RoHS/REACH/UL declarations are provided with the shipment documentation.
