Product details

What this frame is and what it needs

The MGP6303XFO is a PowerPacT 4 basic frame — a 630 A, 3-pole panel-mounted breaker chassis without a trip unit. The 630 A frame is sized for 400/630 A panelboard feeds, and the 3-pole configuration suits three-phase distribution in commercial or industrial switchboards. It is suitable for isolation per BS EN 60947-2, with a visible contact position indicator.

Panel-mounted via backplate, accepting horizontal or vertical orientation. The 4-module 35 mm footprint (140 mm wide, 255 mm high, 110 mm deep) fits standard switchboard cutouts. IP40 enclosure protection keeps out tools and debris but not moisture — install in a dry indoor panel. IK07 impact resistance covers incidental hammer or tool strikes during installation.

Breaking capacity and duty

Electrical durability is 8000 cycles at 440 V In.
