It integrates with standard industrial panels and distribution boards that require a 3-pole protective device for three-phase systems.

Use cases and applications

• Maintenance or retrofit on industrial control panels, switchgear, and distribution boards that require 630A protection
• Replacement for aging or failed breakers in motor control centers and large electrical feeders
• Three-phase protection for manufacturing lines, processing plants, or data-center infrastructure where robust protection matters

Compatibility and verification

Before ordering, confirm fit and ratings using the documented part number. The LGC3630NN reference is the best guide to compatibility with your equipment. If your system manual lists this exact part number and amperage, you’re on the right track.

Installation and handling tips

• Handle with care and store in original packaging until installation
• Follow your site’s electrical safety procedures and manufacturer torque specifications for mounting and electrical connections
• Ensure the surrounding panel or enclosure is rated to support 630A service and three-phase protection
