Why Choose the ABB TVOC-2-DP20 Arc Detector?
The ABB TVOC-2-DP20, order code 1SFA664003R1200, is a 20 m optical arc detector designed for the ABB TVOC-2 Arc Guard System. It detects the intense light produced by an electrical arc fault and communicates the optical signal to the Arc Guard system, enabling rapid protective action within electrical switchgear.
As part of ABB’s TVOC-2 arc-flash protection platform, the detector is factory calibrated and requires no on-site adjustment. This simplifies installation and helps provide consistent detection performance. The detector can be connected to the TVOC-2 main unit or a compatible extension unit, allowing optical sensing points to be positioned throughout low- and medium-voltage switchgear.
The TVOC-2-DP20 incorporates a 20 m optical fibre cable, making it particularly suitable for larger switchgear assemblies or installations where the detector must be positioned a significant distance from the Arc Guard unit. Its extended cable length provides flexibility when protecting busbar, breaker, cable and other switchgear compartments.

Rapid Optical Detection for Arc-Flash Protection
Electrical arc faults can release substantial energy within switchgear in a very short period, making rapid detection and interruption critical. The TVOC-2 Arc Guard System uses optical detectors positioned at strategic locations within the switchgear to detect the characteristic intense light generated by an arc fault and initiate the protection sequence.
The 20 m cable of the TVOC-2-DP20 provides considerable installation flexibility, allowing the optical sensing point to be located remotely from the Arc Guard unit. Multiple detectors can be distributed throughout a switchgear assembly to increase coverage, with the modular TVOC-2 system supporting installations with up to 30 sensors.
Typical Applications
- ABB TVOC-2 Arc Guard System installations.
- Low-voltage switchgear and switchboards.
- Medium-voltage switchgear assemblies.
- Industrial power distribution systems.
