Product details

Overview

The C40R35E400 is a Schneider ComPacT NSX molded case circuit breaker rated 400 A at 40 °C with a 200 kA breaking capacity (Icu) at 690 V AC, built around the MicroLogic 5.3 E electronic trip unit. It carries L, S, and I protection curves, an integrated energy meter, and an LCD display for demand values, power quality, and event logs.

Compared to the C63H4, the C40R35E400 delivers a 200 kA breaking capacity versus 85 kA, making it the correct choice for high-fault-current installations where the C63H4's 85 kA would not clear a 200 kA prospective fault.
