Product details

Overview

The C40W36M320 is a Schneider ComPacT NSX molded case circuit breaker, 3-pole, rated 320 A with a 100 kA interrupting capacity at 690 V AC, fitted with a MicroLogic 6.3 E-M electronic trip unit. It carries L, So, I, and G protection functions, an LCD energy meter, and a Class II front face — suited for distribution panels requiring coordinated protection and metering in one device.

Compared to the C40F4, the C40W36M320 carries a lower continuous rating (320 A vs 400 A) but a higher interrupting capacity (100 kA vs 85 kA), making it the choice when fault current headroom matters more than ampacity.
