Eaton MPS85N3WEAXX2H Magnum low voltage power circuit breaker - UL Listed
Part Number: MPS85N3WEAXX2H
Quick Summary
Magnum low voltage power circuit breaker protects electrical systems by interrupting load current in industrial automation and power distribution. When downtime and arc flash risk escalate, you need fast selective protection that won't disrupt other feeders. This model carries UL Listed and CSA Certified markings, CE compliance, and SABA/NEMA alignment for global installations. The integration with Power Xpert Release trip units and PXR20 LSIAM enhances coordination, simplifies commissioning, and reduces energy waste. For procurement efficiency and system reliability, consider compatibility with Magnum PXR, a reliable choice for panel builders and integrators. Its robust design supports long service intervals and predictable maintenance budgets.

The Magnum MPS85N3WEAXX2H includes a Power Xpert Release trip unit (PXR20 LSIAM) as standard, delivering precise protective coordination with upstream devices, minimizing nuisance trips, and meeting selective coordination requirements for industrial control panels and switchgear. This feature translates into fewer unplanned outages and safer, faster fault clearance in high-demand environments. The design also supports a three-pole, drawout vertical mounting, which simplifies installation, testing, and maintenance while enabling straightforward retrofits in existing assemblies and new builds across manufacturing floors and distribution panels. With an 85 kA interrupting capacity, the breaker withstands high fault levels common in heavy industry, protecting feeders and reducing the need for upsizing devices in critical lines. The double standard frame and 5000 A frame rating provide scalable protection across larger power systems, promoting standardization and inventory efficiency. Certifications and compliance—CE Marked, UL Listed, CSA Certified, and more—ensure global deployment with minimal regulatory hurdles, accelerating project timelines. Finally, this unit integrates smoothly with Magnum PXR documentation and the Power Xpert Protection Manager ecosystem, enabling faster commissioning, real-time diagnostics, and improved maintenance planning for plant-wide reliability.

FAQs
MPS85N3WEAXX2H employs a drawout vertical mounting designed for Magnum PXR frames and standard double-frame configurations. It fits in switchgear, motor control centers (MCCs), and distribution panels used in manufacturing and process industries. Always confirm alignment with mounting rails and follow Eaton installation guidelines to ensure proper clearances and wiring access during retrofits or new builds.
The unit is three-pole with a drawout vertical mount and delivers an 85 kA interrupting capacity. It uses the PXR20 LSIAM electronic trip unit for advanced protection, with physical dimensions of 16.3 in (depth) by 16.8 in (height) by 31.1 in (width), and a weight of 237 lb. These specs support robust protection in demanding industrial environments.
Yes. The MPS85N3WEAXX2H is designed for large distribution systems, MCCs, and industrial switchgear. Its PXR20 LSIAM trip unit provides selective coordination with upstream devices, improving uptime. Its 85 kA capacity and drawout design support safe motor starting scenarios and rapid fault isolation, making it a strong choice for manufacturing and process facilities.
This breaker carries UL Listed and CSA Certified markings, CE compliance, and additional certifications such as NEMA and CCC where applicable. It also aligns with other international certifications (Lloyd’s Register, DNV GL, ABS) in the product family, supporting global deployment and regulatory acceptance across diverse markets and project specs.
Integrating the PXR20 LSIAM trip unit enables precise protection coordination, reducing nuisance trips and enabling faster fault clearance. This translates to lower downtime, easier commissioning via Power Xpert Protection Manager, and improved maintenance planning with richer diagnostics. Over the lifecycle, this delivers meaningful uptime benefits and predictable operating costs for plants with large-scale electric distribution.
