VAMP LTD'S Vamp 221 system uses specialized arc light sensing technology, providing faster and more efficient protection than stand alone over-current relays or busbar differential schemes. It can be programmed to sense electric arc conditions using either simultaneous light and current data, or light sensor information only. Comes with its own keypad, display, and LED indicators.
