Certified to enhance safety

Arc-resistant Magnum DS switchgear is certified ANSI Type 2B. This rating certifies the arc-resistant rating 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. This rating offers superior protection against arcs in breaker, bus or cable compartments with no increase in footprint over Magnum DS switchgear.
