Arc-flash relay fits tight footprints

LITTELFUSE AF0100 compact, cost-effective arc-flash protection relay is sized to fit tight footprints, approx. 30% smaller than previous models. Measuring 90mm high x 128mm wide x 60mm deep and both DIN-rail and surface-mountable, device can be retrofitted easily into existing switchgear or pre-installed in new equipment with little or no configuration. Device detects light from an impending arc-flash and rapidly trips to reduce potential damage. Its two light sensor inputs accept point sensors and fiber optic sensors in any combination for installation flexibility. http://www.littelfuse.com/arcflash
