Why Choose the ABB TVOC-2-COM Communication Kit?
The ABB TVOC-2-COM, order code 1SFA664002R4001, is a dedicated communication module for the ABB Arc Guard System TVOC-2. It adds a Modbus RTU communication interface to the TVOC-2 system, enabling arc-monitor information to be integrated with compatible monitoring, automation and electrical distribution management systems.
Designed specifically for the TVOC-2 Arc Guard platform, the communication module can be installed directly on the TVOC-2 main unit or on the cabinet door. Door mounting provides convenient access and system overview while allowing the Arc Guard main unit to remain installed within the switchgear assembly.
The TVOC-2-COM provides a practical upgrade path for installations requiring remote communication from the Arc Guard System. ABB supplies the module with door-mounting accessories, and its Modbus RTU interface allows TVOC-2 operating and event information to be incorporated into compatible supervisory systems.

Communication and Remote Integration for the TVOC-2 Arc Guard System
The TVOC-2-COM extends the ABB Arc Guard System beyond local arc-fault protection by providing a Modbus RTU interface for communication with compatible supervisory equipment. This enables information from the TVOC-2 installation to become part of a wider electrical monitoring and automation architecture.
Installation flexibility allows the module to be fitted directly to the Arc Monitor or positioned on the cabinet door. This makes the TVOC-2-COM suitable both for new Arc Guard installations and for compatible existing TVOC-2 systems that require additional communication capability.
Typical Applications
- ABB TVOC-2 Arc Guard System communication.
- Low-voltage switchboards and switchgear assemblies.
- Industrial power distribution systems.
- Motor control centres.
- Arc-fault protection system monitoring.
- Modbus RTU integration with compatible control and monitoring systems.
- Communication upgrades for compatible existing TVOC-2 installations.
