Eaton MPS8403MEAXXSW Magnum LV Breaker - UL Listed

The Magnum low voltage power circuit breaker is built for heavy-duty protection in demanding MCC environments, with a three-pole configuration and a drawout vertical form factor that supports motorized racking for safer maintenance. This translates to reduced downtime and safer field operations as technicians can rack the breaker without exposing themselves to live parts. The device is rated for a 4000 A withstand and an 85 kA interrupting capacity, providing robust fault handling for high-current start-up and short-circuit events in large plant installations. With dimensions of 16.3 in depth, 16.8 in height, and 31.1 in width, and a weight of 237 lb, it fits standard double-frame enclosures while offering ample space for future accessories and wiring. Compliance to CE Marked, NEMA Compliant, SABA Listed, and CCC Marked requirements, alongside certifications from CSA, UL, Lloyd’s Register, ANSI, KEMA, ABS, and DNV GL, ensures global acceptance across multinational projects. Although this unit ships without a trip unit, it is designed to pair with Power Xpert Release trip units to enable selective coordination and faster protection decisions. This compatibility supports modular upgrades, reduces total cost of ownership, and aligns with modern cyber-secure protection strategies via the PXr ecosystem. In practical terms, installers benefit from documented application guidance such as zone selective interlocking and selective coordination papers, which help optimize protection schemes in complex distribution networks.
