Description
The TVOC-2-240 Arc Monitor is the main unit of ABB’s Arc Guard System, designed to detect arc faults rapidly.
It senses arc light within 1 millisecond, protecting personnel and electrical equipment from damage.
Moreover, it supports up to 10 detector inputs and can directly trip three breakers to mitigate faults efficiently.
Up to two extension units increase detector inputs to 30, allowing flexible deployment in complex switchgear designs.
Key Features
This arc monitor delivers fast and reliable arc detection for industrial applications.
In addition, it includes an HMI interface that can be mounted outside switchgear doors for operator visibility.
Key Features:
- Detects arc light in 1 ms for rapid fault response
- Supports 10 detector inputs, expandable to 30 with extensions
- Trips up to three breakers simultaneously
- Wall-mounted or DIN rail installation
- Compatible with 100–240 V AC/DC supply
- Includes screw terminal connections for secure wiring
- Variety of detector lengths to suit switchgear configurations
