Product Description
The ABB TVOC-2-240 (1SFA664001R1001) is the intelligent Arc Monitor Unit within the ABB Arc Guard System™, designed to detect arc flash light emissions and initiate rapid power disconnection in less than one millisecond. By combining optical detection with high-speed tripping signals, it significantly enhances operator safety and minimizes equipment damage during electrical faults.
This main unit supports up to ten light sensors and three breaker outputs, offering true zone-selective protection. Moreover, it can be expanded with two extension modules, supporting up to thirty detectors in total—making it ideal for complex power distribution networks. The TVOC-2-240 features a user-friendly HMI for external door mounting and communicates seamlessly via Modbus RTU or BACnet MS/TP, allowing easy integration with modern automation and building management systems.
