1SFA664003R1020 ABB TVOC-2-DP2 Optical Arc Detector 2 m

Why Choose the ABB TVOC-2-DP2 Arc Detector?

The ABB TVOC-2-DP2, order code 1SFA664003R1020, is an optical arc detector with a 2 m fibre-optic cable designed for use with the ABB TVOC-2 Arc Guard System. Installed within switchgear compartments, the detector monitors for the intense light produced by an arc flash and provides the optical detection input required by the TVOC-2 arc monitor.

Each detector consists of a fibre-optic cable connected to an optical lens. The lens provides a wide 180° detection angle and can detect arc-flash light at distances of up to approximately 3 m, depending on the intensity of the light. This allows strategic positioning of detectors throughout switchgear to provide effective optical coverage of areas where an arc fault could occur.

With its 2 m detector cable, the TVOC-2-DP2 is suitable for positioning within individual switchgear sections and electrical compartments while connecting back to compatible TVOC-2 equipment. ABB's Arc Guard System uses rapid optical detection to help minimise the duration and resulting energy of an arc-flash event.

Reliable Optical Detection for Arc-Flash Protection

An electrical arc produces an extremely intense burst of light and heat. The ABB TVOC-2 Arc Guard System uses optical detectors such as the TVOC-2-DP2 to identify this light rapidly. When an arc is detected, the TVOC-2 monitor can send a trip signal to the associated circuit breaker, helping shorten the duration of the fault and reduce the arc energy released within the switchgear.

The TVOC-2-DP2 detector's fibre-optic construction and wide viewing angle allow it to monitor critical areas without requiring complex active electronics at the sensing point. Multiple detectors can be strategically positioned within a switchboard to provide optical coverage of busbar sections, breaker compartments and other areas where an arc fault could develop.

Typical Applications

• ABB TVOC-2 Arc Guard protection systems.
• Low-voltage switchboards.
• Industrial switchgear assemblies.
• Busbar and circuit-breaker compartments.
