Description
Part of the PowerPacT L-Frame family, this 400A automatic molded case switch acts as a high-capacity disconnect for commercial and industrial facilities. It features a fixed magnetic trip for instantaneous response without thermal overload protection. The device installs into Square D I-Line panelboards and switchboards, serving as a drop-in replacement for older LA36000 and LH36000 models. A robust 125kA rating at 240V ensures exceptional current-limiting performance under fault conditions.Specifications
