Quick Summary

Magnum low voltage power circuit breaker is a high-capacity protective device for fast isolation of large feeders in industrial facilities. Engineers often struggle to balance selective coordination with minimizing nuisance trips in complex motor and distribution networks. This unit carries UL Listed, CSA Certified, and CE Marked credentials, plus 1600 A Iu and 100 kAIC ratings for reliable protection. Because it fits standard Magnum frames and supports optional Magnum PXR trip units, it streamlines procurement and installation across existing switchgear, reducing lifecycle costs and simplifying maintenance. In practice, it delivers robust protection for critical loads while remaining adaptable to panel configurations and OEM requirements.

FAQs

This unit features a four-pole, fixed horizontal mounting on a standard Magnum frame. Plan for panel space, bus-bar alignment, and clearance for maintenance. It arrives without a trip unit, so you can install a Magnum PXR trip unit if tailored protection is required. Ensure compatibility with existing switchgear details and enclosure dimensions before retrofit.
Key specs include a 1600 A Iu rating for continuous operation and a 100 kAIC interrupt rating for fault energy handling. The combination supports high-energy fault interruption on large feeders, aiding selective coordination and minimizing downstream damage. Compliance with UL Listed, CSA Certified, and CE Marked standards further reinforces reliable performance in regulated environments.
Yes, its four-pole, standard-frame design makes it suitable for motor feeders and switchgear within panel boards and MCCs. For maximum benefit, pair with compatible Magnum PXR trip units to tailor protection curves. The base unit’s no-trip configuration offers flexibility for projects planning phased protection upgrades or custom coordination schemes.
The MPSC164HEAXXSW carries UL Listed, CSA Certified, and CE Marked credentials, along with additional certifications from Lloyd's Register, KEMA, ABS, and DNV GL. This broad certification footprint supports North American and global compliance, facilitating procurement, audits, and cross-border installation in regulated industries.
Benefits include reduced nuisance trips through coordinated protection, robust fault-energy handling that minimizes equipment damage, and streamlined retrofits with standard Magnum frames. While maintenance intervals depend on site conditions, the unit’s compatibility with Magnum PXR trip units and widespread certifications help lower lifecycle costs by simplifying spare parts consumption and supplier qualification.
