Description: The TVOC-2 Arc Protection system is an arc protection relay that reduces arc failures and helps protect people and equipment. The arc monitor is the main unit of the arc protection system, which detects the arc light and sends an electrical signal through the fast IGBT contact to a nearby circuit breaker within 1 ms, thereby cutting off the power supply and exploding the arc. The arc monitor has 10 detector inputs and can trigger up to three circuit breakers with area selectivity if needed. Up to 2 expansion units can expand the number of light detectors to 30, and the unit includes an HMI that can be placed on the outside of the door. Detectors are sold in a wide range of lengths to accommodate complete switchgear designs. Supply voltage 100… 250 volts DC or 100 volts… 240 volts AC 50/60 Hertz. Accessories include electric influenza measuring unit, optical cable, cable belt, etc.
