Eaton MPS8503WEAXXSW Magnum LV Circuit Breaker - UL Listed

High interrupting rating and Magnum PXR compatibility enable protection for high-load feeders across complex distribution networks. By delivering fast fault clearing, they minimize energy let-through and limit arc flash exposure for plant personnel. This capability supports selective coordination between main and feeder breakers, reducing the risk of unnecessary trips. Industrial facilities such as data centers, chemical plants, and automotive assembly lines particularly benefit from these robust protection characteristics. Drawout vertical mounting simplifies installation logistics and subsequent maintenance in tight spaces. The design provides clear access for inspection, testing, and replacement without disturbing adjacent devices. Panel designers appreciate the compatibility with standard Magnum frames and existing switchgear footprints. Faster swaps translate into lower downtime during maintenance windows, outages, or panel upgrades. This is especially valuable for retrofit projects where downtime must be minimized. Trip-unit-free base variants can be paired with Magnum PXR trip units to tailor protection. Engineers can set precise tripping curves and coordination logic to match process requirements. This flexibility reduces upfront capital expenditure while enabling phased protection upgrades. Coupled with compatible accessories, these breakers adapt to changing safety and performance standards. That adaptability supports long-term capacity planning in evolving facilities. Global certifications such as UL Listed, CE Marked, and CSA Certified simplify procurement and audit readiness. Compliance with multiple standards accelerates approvals in multinational projects and contractor handovers. Engineers gain confidence that equipment meets industry-specific safety, reliability, and performance criteria. These credentials also assist with warranty validation and service supplier qualification. Lifecycle support is reinforced by Magnum renewal parts, accessories, and official manuals. Access to quick-start guides and application notes helps accelerate commissioning and reduce downtime. Power Xpert Protection Manager compatibility enables remote monitoring for preventive maintenance. Together, these resources lower maintenance costs and extend asset life.
