Eaton Magnum low voltage power circuit breaker MPS85N4MEAXX2Q - UL Listed, 85 kAIC

The MPS85N4MEAXX2Q delivers high-current protection with a 5000 A rated uninterrupted current (Iu) and an 85 kAIC interrupt rating, directly reducing the risk of damage to motors, feeders, and downstream equipment in the event of a fault. Business impact: increased system availability and reduced repair costs, especially in high-demand manufacturing lines and critical process loops. Application: suited for main feeders and motor control centers in process automation where fast fault clearance is essential. The drawout vertical mounting with motorized racking simplifies maintenance and replacements, shortening downtime during device swaps and upgrades. This translates to lower maintenance labor and safer live-operations work, aligning with industry best practices for panel construction and retrofit projects. The PXR25 LSI ARMS trip unit provides precise protection coordination, enabling selective tripping and arc-energy management that minimizes unnecessary outages. Compatibility with Magnum frames and double-standard construction ensures seamless integration into existing Eaton protection schemes and OEM builds. In practice, engineers gain predictable trip characteristics, improved fault isolation, and easier compliance verification during commissioning. The device’s comprehensive certifications and compliance footprint support global deployment, from North American facilities to CE-marked installations in Europe.
