Arc-resistant Magnum DS low-voltage switchgear (ArcGard)

Arc-resistant switchgear is designed to safely contain and redirect arc flash energy away from the operator. Eaton's ArcGard Arc-resistant Magnum DS switchgear has been tested in all three compartments for a full 0.5 seconds (30 cycles), passing the ANSI/IEEE C37.20.7, Type 2B test guide at 100 kA, 508V and 85 kA, 635V, including an industry-exclusive Type 2B rating for the secondary door above the breakers.

Arc-resistant Magnum DS low-voltage switchgear (ArcGard)
Up to 600 V
Up to 6000 A
Up to 100 kAIC

Core features

  • Third party tested to IEEE C37.20.7 test guide for arc-resistant switchgear
  • Draw-out low voltage power circuit breakers while maintaining Type 2B rating
  • Engineered-to-order configurations
  • UL 1558, rear access cable compartment
  • Short circuit withstand rating up to 85kAIC @ 635Vac and up to 100kAIC @ 508Vac
  • 30 cycle (0.5 second) short-time withstand rating
  • Up to 10,000A continuous current –horizontal main bus
  • Up to 5,000A continuous current – vertical riser bus
  • Plenum & direct venting available to direct arc gasses to top of the enclosure
  • NEMA 1 enclosure, with either top or bottom cable or bus duct entry 

Certified to enhance safety.

ANSI Type 2B is certified arc-resistant around the entire perimeter of the equipment, even when the low voltage instrument compartment door and the secondary door above the breaker door are open. Type 2B rating offers superior protection against arcs in breaker, bus or cable compartments with no increase in footprint over Magnum DS switchgear.
