The ABB TVOC-2-DP10 is a fiber-optic arc flash detector for the TVOC-2 Arc Guard System, engineered for fast, dependable arc flash detection in switchgear applications. By sensing the earliest light emission of a fault, it helps trigger mitigation in time-critical situations, protecting personnel, minimizing equipment damage, and reducing downtime.

Each detector pairs a 10 m fiber-optic cable with a high-sensitivity lens that supervises a 180° field of view. It captures the intense light signature of an arc up to 3 m away, depending on light intensity, enabling the TVOC-2 to trip within milliseconds. Passive optical sensing delivers immunity to electromagnetic interference and safe operation inside metal-enclosed switchgear. The detector is panel-mounted and connects directly to the TVOC-2 main unit or an extension module for flexible placement across compartments.

Ideal for new-build and retrofit projects in low- and medium-voltage switchgear, the TVOC-2-DP10 streamlines engineering, accelerates commissioning, and supports arc flash mitigation strategies; for added peace of mind, it comes with a 1-year warranty.
