Magnum PXR switchgear, brings a new look along with the integration of Power Xpert Release trip units, providing what you expect and much more, with added safety features, enhanced functionality and communications. Rear access Lower installation and maintenance costs, higher interrupting and withstand ratings, enhanced safety, higher quality, reliability and maintainability Front access When floor space is limited, or room constraints dictate that equipment be mounted against a wall, why compromise on switchgear design? Eaton's Magnum PXR front-accessible switchgear combines the robustness of UL® 1558 low-voltage switchgear with the flexibility of UL 891 switchboard design. The front-accessible switchgear offering allows mounting against a wall, or in other tight locations, where a standard rearaccessible switchgear lineup would not normally fit. · UL 1558/891 · Up to 10,000 A continuous current horizontal main bus · Up to 5,000 A continuous current vertical riser bus · Short circuit withstand rating of 100 kA. · Bus standard bracing is 100 kA optional 150 kA · 4-wire applications, 100% neutral · Eaton PXR trip unit with digital display, programming through the Power Xpert Power Management (PXPM) software via micro-B USB · Optional safety shutters · Rear cover or doors · Control wire standard Type SIS insulated stranded copper. · Integrated LV-HRG optional (LV-HRG can be stand alone or wall mount) · MPN 4000 A in 30" structure · 508 Vac--100 kAIC maximum short circuit · 635 Vac--65 kAIC maximum short circuit Levering Magnum PXR breaker through the door Integrated HRG 3 EATON Magnum PXR low-voltage switchgear · UL 1558 · Up to 6,000 A continuous current horizontal main bus · Up to 5,000 A continuous current vertical riser bus · Bus standard bracing is 100 kA optional 150 kA · 600 Vac class · NEMA 1 indoor · NEMA 3R outdoor, both aisle and aisleless enclosures · Standard 40.20-inch switchgear depth · Up to 4-high breaker arrangement · Breaker sections are 18, 22 or 44 inches wide · Cable compartments are 18, 22, 30 or 44 inches wide Improved maintainability with dedicated secondary terminals with separate access door and front accessible control wireway Increased reliability with modular design allows for reduced parts for both structures and breakers Reduced installation cost with front- accessible controls and wiring enables rapid installation and commissioning Shown with plenum.

Arc Quenching Arc Quenching Switchgear detects and contains an arc fault in less than 4 milliseconds, drastically reducing the incident energy. It works by detecting the ignition of an arc inside the switchgear using the Eaton Arc Flash Relay and transferring it to the Arc Quenching Device. Arc Quenching Switchgear transfers the arc by creating a lower impedance arc, not a bolted fault, safely contained inside the Arc Quenching Device. This reduces the peak fault current by at least 25% and puts less stress on upstream equipment during an arc fault. · Tested to ANSI/IEEE C37.20.7, Type 2B test guide in NEMA 1 construction · Arc Quenching Device (AQD) is a UL Recognized Component per UL 2748 · Short circuit withstand rating up to 100 kA at 635 V ac · <4 ms arc quenching time · >25% reduction in peak fault current · >44% reduction in peak system stress · Complete system selfsupervision with health status communicated via Modbus and dry contacts · Anti-nuisance trip technology · Available in rear access and front access switchgear configurations · Available in NEMA 1, and NEMA 3R walk-in enclosure types · Exceptional incident energy reduction · Enhanced safety · Advanced switchgear protection · Dramatically reduced downtime 5 EATON Magnum PXR low-voltage switchgear Remote racking device The MRR1000 permits the operator to open and close a breaker from up to 25 feet away during the rack-in or withdraw process, well beyond the arc flash boundary. Cable lashing device The Cable Lashing Device can be used to secure cables faster, easier and more reliably when compared to the traditional rope lashing method. MagnumTM PXR shutter module The Magnum PXR shutter module is used to test the operation of the shutters with the breaker removed. It also permits access to the bus stabs for inspection and testing. Integrated testing Integrated testing with the use of Power Xpert Protection Management (PXPM) removes the need for costly and potentially complicated external test kits Automatic transfer and intelligent control packages pre-engineered · flexible · smart Low-voltage switchgear elevation nd one line view Eaton's Magnum PXR low-voltage switchgear offers optional pre-engineered automatic transfer and intelligent control packages with features that can be modified to meet specific requirements.
