The ABB TVOC-2-E1, order code 1SFA664002R1001, is a dedicated extension unit for the ABB TVOC-2 Arc Guard System. Designed to expand the optical detection capacity of a TVOC-2 installation, it provides 10 additional optical detector inputs for monitoring multiple locations within electrical switchgear and distribution equipment.
The extension unit mounts directly onto the TVOC-2 main unit, providing a straightforward way to increase the number of arc detectors connected to a single Arc Guard system. Up to two TVOC-2-E1 extension units can be added to the main unit, allowing a TVOC-2 system to accommodate up to 30 optical detector inputs in total.
Designed specifically for ABB’s rapid arc-flash protection platform, the TVOC-2-E1 helps extend optical coverage across larger or more complex switchgear assemblies. Its compact construction, low 1 W power loss and operating temperature range of -25 to +55 °C make it suitable for demanding industrial electrical installations.
Arc-flash protection relies on rapid detection of the intense light generated by an electrical arc fault. Multiple optical detectors can be positioned throughout switchgear compartments so that faults can be detected quickly across different sections of an electrical assembly. The TVOC-2-E1 increases the number of detector connection points available to the TVOC-2 Arc Guard System.
Each TVOC-2-E1 provides 10 additional optical inputs, making it possible to extend protection coverage without installing a separate Arc Guard main unit. This modular architecture is particularly useful for larger switchboards, where detectors may be required across busbar, breaker and cable compartments.
