Quick Summary

Eaton Magnum low voltage power circuit breaker is designed to protect distribution panels and industrial equipment from overcurrents and short circuits. For engineers and maintenance teams, selecting the correct frame, isolation, and mounting configuration can slow projects and create risk when panel clearance or enclosure compatibility is overlooked. This Magnum breaker carries essential certifications — CE Marked, UL Listed, and CSA Certified — along with NEMA compliance, supporting global deployments and cross-border sourcing. Designed for integration in standard enclosures with a double standard frame and four poles, it supports scalable protection while keeping installation straightforward. Although shipped without a trip unit, it remains compatible with the Magnum PXR family for future upgrade, enabling a seamless move to Power Xpert Release protection without replacing the base frame.

FAQs

This unit ships without a trip unit but is designed to be compatible with Magnum PXR trip units for future upgrades. It features a four-pole, double-standard frame with fixed horizontal mounting, enabling straightforward integration into standard panels and control cabinets. Plan to pair with a PXR release module when protection needs evolve.
Key ratings include rated uninterrupted current Iu of 5000 A and an interrupt rating of 85 kAIC. These specs determine suitability for high-load feeders and fault-level environments, reducing the likelihood of device failure during faults and enabling selective coordination in large motor and distribution circuits.
Yes. The four-pole Magnum frame is designed for three-phase systems with neutrals, and the 85 kAIC interrupt rating supports motor startup surges and fault events. Its dimensions and mounting are optimized for standard enclosures, making it a solid choice for MCCs and main distribution panels in industrial facilities.
The product carries UL Listed and ANSI certifications, CSA Certified, and CE Marked, with additional compliance such as NEMA. It also aligns with CCC Marked and SABA Listed requirements where applicable, supporting international projects and stringent procurement standards.
With the option to upgrade to Power Xpert Release trip units later, the base frame investment remains valid for years. High fault protection minimizes downtime, and global certifications reduce procurement risk. The sturdy Magnum frame supports long service intervals in demanding industrial environments, contributing to predictable lifecycle costs.
