Product details

The C63V31M500 is a ComPacT NSX630HB1 frame circuit breaker, 3-pole, rated 500 A at 65 °C with a MicroLogic 1.3 M electronic trip unit. It ships as a complete breaker — toggle handle, front-connect terminals top and bottom, and the trip unit installed. No earth-leakage module is fitted (the listing shows 'Without' for earth-leakage protection), so if your spec calls for Vigi add-on, that's a separate order. The kit includes the flashing green LED for ready-to-operate status. IP40 enclosure, IK07 impact rating — panel-side handling is fine, but it's not a washdown part.

This breaker carries an 85 kA Icu at 500 V AC, 80 kA at 525 V, and 75 kA at 690 V — all per IEC 60947-2. The 500 A trip rating is at 65 °C ambient; if your panel runs hotter, factor the thermal derating curve. Utilisation category A (no intentional short-time delay) means it's a fast-clearing device — fine for motor branch circuits where coordination with downstream starters is handled by the trip curve.

Connection pitch is 45 mm. Six accessory slots available.

Frequently asked questions
