Description
The ABB TVOC-2-240 is a high-performance arc monitor designed for industrial environments where safety is paramount. It detects light from electrical arc faults and rapidly triggers protective actions, such as disconnecting power in under a millisecond, thereby preventing equipment damage and safeguarding personnel. It’s extensively used in power stations, manufacturing plants, oil refineries, and electrical distribution networks, where arc faults pose serious risks. The ABB TVOC-2-240 is an essential part of arc suppression systems, providing early detection and intervention to minimize fire hazards, equipment downtime, and potential injury.
This model is adjustable for a wide operating voltage range of 100-240 VAC/DC, with a compact measurement footprint suitable for mounting on walls or DIN rails. It supports up to 10 optical inputs, connecting multiple detectors across large switchgear assemblies, and can control up to three circuit breakers with zone selectivity. Its high-speed response (approximately 1 millisecond) makes it highly effective in rapidly clearing arc faults. The unit includes a Graphic LCD interface for easy configuration, real-time monitoring, and diagnostics. Its rugged construction ensures compliance with IP54 standards, providing sufficient environmental protection for industrial applications operating in temperatures from -25°C to 55°C.
