Eaton MPSC164MEAXX2S Magnum LV Breaker - UL Listed
Part Number: MPSC164MEAXX2S
Quick Summary
Eaton Magnum low voltage power circuit breaker protects industrial power distribution and feeders. Engineers often face downtime and safety risks from miscoordination, which can escalate with complex rack configurations and non-intuitive trip schemes; this unit mitigates those risks with motorized racking and a Power Xpert Release trip unit for fast, reliable protection. The design is CE marked and UL listed, with ANSI and CSA compatibility to streamline global procurement and compliance. As a high-current, four-pole, drawout solution, it supports scalable protection, reduces total cost of ownership, and integrates smoothly with Power Xpert Protection Manager for centralized monitoring and coordination across your plant.

FAQs
Yes. The MPSC164MEAXX2S uses a standard Magnum frame and drawout vertical mounting, designed for straightforward replacement in typical LV switchgear and switchboard layouts. It supports common configurations and aligns with Power Xpert Protection Manager for centralized monitoring, reducing retrofit complexity and project risk.
Key specs include a 1600 A current rating and a 100 kA short-circuit withstand at the specified frame, four-pole configuration, and the PXR25 LSIGAM trip unit. These parameters enable robust protection for feeders and motors, with precise coordination to minimize nuisance trips and expand fault-clearing reliability.
Ideal for manufacturing, process facilities, data centers, and large machine cells requiring high-current protection with reliable coordination. The four-pole, drawout design supports main feeders and critical loads, while motorized racking simplifies maintenance in plants with limited downtime tolerance.
The unit is CE Marked and UL Listed, with ANSI and CSA certifications, plus additional approvals. This broad certification footprint simplifies global procurement, enables easier regulatory audits, and reduces risk when integrating with international equipment and service providers.
Integration with Power Xpert Protection Manager enables centralized protection management, faster fault diagnosis, and predictive maintenance planning. While upfront costs may be higher, the improved uptime, reduced maintenance frequency, and better coordination translate into a favorable total cost of ownership over the machine and facility lifecycle.
