Product details

Overview

The C63N37E570 is a Schneider ComPacT NSX molded case circuit breaker rated 570 A continuous at 40 °C, with an 85 kA interrupting capacity (ICu) at 440 V AC, 3-pole, and fitted with a MicroLogic 7.3 E electronic trip unit that provides L, S, I, and earth-leakage (R) protection curves.

The 85 kA ICu at 440 V AC gives this breaker headroom for high-fault installations; the 570 A frame and MicroLogic 7.3 E trip unit suit distribution feeders where earth-leakage detection is required alongside overload and short-circuit protection.

Compared to the C63H4, which is a 4-pole basic frame rated 630 A at 690 V AC, the C63N37E570 is a 3-pole earth-leakage breaker rated 570 A at 440 V AC — pick the C63H4 when the BOM requires 4 poles or a higher voltage rating, and the C63N37E570 when earth-leakage protection and a lower voltage distribution system are specified.
