Product details

The C63N35E630 is a fixed-mount, 3-pole ComPacT NSX circuit breaker rated 630 A at 40 °C, fitted with a MicroLogic 5.3 E electronic trip unit. Front connections top and bottom keep wiring runs clean in a panel — no rear-access gymnastics needed.

Trip unit and metering

The LCD display shows real-time load data and trip event details.

Construction and environment

Terminals accept up to 240 mm² aluminium or copper conductors via four screw-type connections. IP40 front-face protection and IK07 impact resistance suit indoor switchgear environments where occasional mechanical knock is a risk.
