Description
Built for commercial applications, this 400A unit-mount breaker includes factory-installed control wire tap lugs. It utilizes thermal-magnetic technology to deliver reliable long-time and instantaneous (LI) protection. The L-frame footprint integrates into Square D switchboards and motor control centers. When replacing this unit, the LJL36400U31X requires an S29348 tap kit. Operating with an extra-high 65kAIC at 480VAC, the current-limiting design provides superior fault protection.Specifications
