Why Choose the ABB TVOC-2-E6-S Extension Unit?
The ABB TVOC-2-E6-S, order code 1SFA664002R6001, is a dedicated extension unit for supervised arc-flash detectors within the ABB Arc Guard System TVOC-2. Designed to expand detector capacity, the module provides 10 optical inputs specifically for ABB supervised detectors, allowing wider switchgear coverage from a single Arc Guard installation.
The TVOC-2-E6-S enhances arc-flash protection by continuously supervising connected detectors. ABB's supervised detector system checks detector functionality at regular intervals, enabling the Arc Guard system to identify a detector that has been disconnected or is not functioning correctly. This provides an additional level of confidence in safety-critical switchgear installations where detector availability is essential.
By adding the TVOC-2-E6-S to a compatible TVOC-2 system, additional supervised optical detectors can be distributed throughout low-voltage or medium-voltage switchgear compartments. The modular architecture allows the Arc Guard system to be expanded as required while retaining the rapid optical arc detection for which the TVOC-2 platform is designed.

Supervised Arc Detection for Enhanced System Reliability
Optical arc-flash protection relies on detectors being available when an electrical arc occurs. The ABB TVOC-2-E6-S extends the TVOC-2 architecture with supervised detector inputs, allowing the system to monitor detector integrity as well as respond to arc-flash light. This helps operators identify detector faults or disconnections rather than leaving them undetected until a protection event occurs.
The extension unit provides 10 supervised optical inputs, making it possible to distribute additional detectors throughout switchgear compartments and improve coverage of potential arc-fault locations. ABB's supervised detectors are tested automatically at regular intervals, while the wider TVOC-2 system provides rapid arc-flash detection and can be expanded to protect multiple switchgear compartments.
Typical Applications
- ABB TVOC-2 Arc Guard protection systems.
- Low-voltage switchgear and switchboards.
- Medium-voltage switchgear assemblies.
- Motor control centres and industrial control systems.
- Electrical distribution and power control installations.
- Arc-flash protection systems requiring supervised detector monitoring.
