High fault-current protection with 100 kA interrupting capacity provides rapid fault isolation, reducing arc energy and equipment damage. This directly lowers mean time to repair and increases overall panel reliability in high-demand environments such as automotive assembly lines or material handling systems. The Magnum PXR20 LSIGAM trip unit enables precise protection coordination, improving selectivity and enabling faster fault clearance in complex power distribution schemes, which translates to fewer unnecessary trips and safer machine operation. The 3-pole configuration with fixed horizontal mounting simplifies installation and panel planning, saving space and reducing misalignment risks in crowded switchgear enclosures. Global certifications including UL Listed, CE Marked, and CSA Certified reduce regulatory risk and streamline procurement across international facilities. Detailed dimensions and the durable double standard frame support long service life in rugged industrial settings, while compatibility with Eaton installation guides and Protection Manager tools aids maintenance planning and spare parts management.
