Levering Magnum DS breaker through the door As a premier leader in power distribution equipment, Eaton offers a wide range of innovative, low voltage switchgear designs providing flexible solutions to optimize operational performance, enhance safety and save space. • UL1558/891 • Up to 10,000A continuous current – horizontal main bus • Up to 5,000A continuous current – vertical riser bus • Short circuit withstand rating of 200,000 amperes with no fuses. • Bus standard bracing is 100,000 amperes – optional 150,000 • 4-wire applications, 100% neutral • Ground the full length of the switchgear assembly • Optional safety shutters • Rear cover or doors • Control wire standard Type SIS insulated stranded copper. • Integrated HRG optional (HRG can be stand alone or wall mount) • MDN 4000A in 30” structure • 508 Vac—100 kAIC maximum short circuit • 635 Vac—65 kAIC maximum short circuit • UL 1558 • Up to 6,000A continuous current – horizontal main bus • Up to 5,000A continuous current – vertical riser bus • 100, 150 and 200 kA bus bracing designs • 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 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 DS 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 rear- accessible switchgear lineup would not normally fit. Rear access Lower installation and maintenance costs, higher interrupting and withstand ratings, enhanced safety, higher quality, reliability and maintainability Integrated HRG NRX integration • 800A continuous current with 65KA short circuit and 42KA short time (30 cycle withstand) for UL 1558 • 1200A continuous current with 65KA short circuit for UL 891 • 24” enclosure – two 3P NRX breakers side by side 2 EATON Low Voltage Switchgear

Arc-resistant gear is designed to safely redirect and contain these arcs should they occur, regardless of the originating location of the arc. ArcGard Magnum DS switchgear has been tested in all three compartments for a full 0.5 seconds, passing ANSI Type 2 and Type 2B standards at 100 kA at 508V and 85 kA at 635V. ArcGard arc-resistant front access Arc-resistant front-accessible switchgear from Eaton provides the robustness and strength of arc-resistant rear-accessible construction, but with the flexibility of an innovative front-accessible design. This unique gear design allows for mounting against a wall, while protecting operating and maintenance personnel from potentially dangerous arcing events. Type 2B secondary compartment 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 Increased safety with complete enhanced performance suite of options Shown with plenum. Can be provided without plenum. Shown without plenum. Plenum and duct can be added upon request. 3EATON Low Voltage Switchgear

Eaton’s Magnum DS low voltage switchgear offers optional pre- engineered automatic transfer and intelligent control pack- ages with features that can be modified to meet specific requirements. The packages are available on both standard and arc-resistant switchgear as well as both front and rear access equipment. Classified by the interface, the automatic transfer and intelligent control packages are as follows: • Eaton ATC-900 controller • Eaton PLC with Eaton touchscreen • Power Xpert™ dashboard Features and benefits Eaton ATC-900 controller This controller can be utilized for transfer in a lineup with Main-Main, Main-Generator or Generator–Generator application (no tie breaker present). This option will include a selector switch for Auto/Manual as well as generator start/stop/exercise. Eaton PLC with Eaton touchscreen Using the Eaton PLC and Eaton touchscreen, Eaton can provide automatic Main-Tie-Main transfer to increase uptime and effi- ciency. The desired sequence of operation can be selected during project quotation. Power Xpert™ dashboard The Power Xpert dashboard is an intelligent collection of views which allow users to configure a switchgear assembly and continuously monitor and control various devices and parameters. The dashboard can be integral to the switchgear assembly or remotely mounted offering a monitoring and control option outside the arc flash zone. It provides features required to maintain a switchgear assembly such as: • Remotely open/close circuit breakers through control mode • Initiate a transfer scheme in a Main/Tie/Main switchgear for uninterrupted power supply • Ability to configure/ monitor alarms for various devices • Provides a rich interface to monitor parameters of all devices and study the trends of those parameters. Automatic transfer and intelligent control packages pre-engineered • flexible • smart Low voltage switchgear elevation and one line view
