High fault current rating and short-circuit withstand: 2500 A / 100 kA reduce damage to feeders and downstream equipment, delivering measurable uptime gains and fewer repairs in critical power paths. Four-pole fixed-vertical mounting streamlines installation, improves panel layout consistency, and minimizes wiring errors during commissioning in large MCCs and switchgear assemblies. PXR20 LSI trip unit enables selective coordination with downstream devices and protection relays, empowering engineers to tailor protection curves for motors and feeders while reducing nuisance trips. Global certifications support multi-site deployments and simplify audits in multinational facilities, shortening procurement and training cycles. Comprehensive documentation and zone selective interlocking resources enhance field installation quality, commissioning speed, and long-term maintenance planning for industrial environments.

FAQs

Designed for fixed vertical mounting in standard frame assemblies, MPSC254VEAXX2A is a four-pole breaker rated up to 2500 A with a 100 kA short-circuit withstand. It fits common panel designs and allows straightforward wiring for main feeders and bus tie circuits. The PXR20 LSI trip unit supports accurate coordination with downstream devices.
Yes. The MPSC254VEAXX2A carries UL Listed and CSA Certified marks, and is CE marked, reflecting compliance with North American and European standards. NEMA compliance is listed, along with ANSI considerations, enabling easier acceptance in mixed markets. This certification footprint helps with audits, reduces field rework, and supports multi-site deployments.
Ideal for main distribution panels and motor feeders in manufacturing, processing, and power-intensive facilities. The four-pole design with high fault withstand supports bussing and large feeders; the PXR20 LSI trip unit enables selective coordination with protection relays and Power Xpert Protection Manager. This aids uptime, minimizes nuisance trips, and simplifies arc-flash mitigation strategies.
Power Xpert Release (PXR) with the PXR20 LSI module provides advanced protection logic including precise trip signals, arc energy reduction, and coordinated tripping with downstream devices. It allows tailored curves for motor protection and feeder protection, improving selectivity. In practice, this reduces mean time to repair and extends equipment life through controlled fault isolation.
Users can consult Eaton’s Magnum PXR breaker manuals and the official spec sheets, available in the downloads section. Additional resources include zone selective interlocking papers and selective coordination studies, plus UL certificates of compliance. For software support, Power Xpert Protection Manager tools assist commissioning and ongoing protection management.
