Directory Description :TVOC-2-240 arc monitor

The TVOC-2 arc protection system is an arc protection relay that mitigates arc failures and helps protect personnel and equipment. The arc monitor, the main unit of the arc protection system, detects the light of the arc and sends an electrical signal within 1 millisecond via a fast IGBT contact to a nearby circuit breaker that disconnects the power supply and extinguishes the arc. The arc monitor has 10 detector inputs and can trip to three circuit breakers if needed, regionally selective. The number of light detectors can be expanded to 30 by up to 2 extension units, which include a human-machine interface that can be placed outside the door. Detectors are sold in a wide range of lengths to accommodate complete switchgear designs. Supply voltage 100… 250v DC or 100… 240v AC 50/60 Hz. Accessories include current sensing unit, optical cable, cable belt, etc.
