Three-pole design with fixed horizontal mounting streamlines installation and minimizes wiring errors, reducing commissioning time in new builds and upgrades. This configuration supports consistent trip coordination with standard frame layouts, improving serviceability in maintenance windows. It is ideal for control panels and machine enclosures requiring reliable, space-efficient protection. High interrupting capacity of 5000 A (ABCABC) and 85 kA short-circuit rating provide robust protection for feeders and large motors, helping minimize arc flash exposure and equipment damage. The rugged frame design supports reliable operation even under transient faults, maintaining system uptime and reducing maintenance costs. Suitable for feeders, conveyors, and large motor drives across manufacturing lines. With dimensions of 31.1 in width by 16.8 in height and 16.3 in depth, and a weight of 237 lb, planning and enclosure space are straightforward, aiding upfront RFQ and installation scoping. The compact footprint fits standardized switchgear racks and panel assemblies, accelerating field deployment and inventory planning. Certified to UL Listed, CE Marked, and NEMA compliant standards, plus CSA and KEMA support, the MPS8503HEAXXSW meets multi-region regulatory demands, reducing the need for alternate parts in global projects. Base-frame design with no trip unit provides a clean baseline protection, while enabling later upgrade to Power Xpert Release trip units if needed. This approach supports scalable protection as a facility grows and new equipment is integrated.
