Arc-Resistant Controller

April 1, 2005
Users of medium-voltage power can receive more safety protection with the Allen-Bradley Centerline ArcShield medium-voltage arc-resistant controller.

The new controller provides rugged, reliable control and protection for utility workers and others working in environments that require high voltages—between 2,300 and 7,200 volts—including petrochemicals and forestry, says the vendor. The ArcShield controller builds on standard safety features of Centerline medium-voltage controllers, bringing new enhancements that protect personnel from arc flashes. Specialized arc vents on the unit’s roof allow an arc flash to escape safely through vents to protect personnel on all four sides of the controller. ArcShield arc-resistant products provide Type 2 accessibility and are tested to the IEEE C37.20.7 standard. The ArcShield medium-voltage controller is available in two standard product formats—18-inch incoming units, and 400 amp, one-high full-voltage non-reversing (FVNR) controllers.
