Product details

Overview

The C63W46E630 is a Schneider ComPacT NSX molded case circuit breaker with 4 poles, rated 630 A at 40 °C, and a breaking capacity of 100 kA IC at 690 V AC. It carries a MicroLogic 6.3 E electronic trip unit providing L, S, I, and G protection. The breaker is fixed-mounted and operates on 60 Hz AC networks.

Alternatives & selection

Compared to the C63H4, the C63W46E630 offers the same 4-pole configuration and 630 A rating but with a higher breaking capacity of 100 kA versus 85 kA. The C63W46E630 includes the MicroLogic 6.3 E trip unit with ground-fault protection, while the C63H4 uses a basic frame without integrated protection. For applications requiring ground-fault detection and higher fault-current withstand, the C63W46E630 is the more capable choice.
