Why Choose the ABB TVOC2-2-240-C Arc Monitor?
The ABB TVOC2-2-240-C, ABB order code 1SFA664001R1003, is an advanced arc flash detection and protection monitor designed for rapid detection of electrical arcs in low- and medium-voltage switchgear. Part of the ABB Arc Guard System TVOC-2 series, it helps protect personnel and electrical equipment while reducing damage and production downtime caused by arc faults.
The TVOC-2 system detects the intense light generated by an electrical arc using optical detectors installed throughout the switchgear. When an arc is detected, the monitor can send a trip signal to the associated circuit breaker in approximately 1 ms, enabling extremely fast isolation of the fault. The main unit provides 10 optical detector inputs and supports expansion to as many as 30 detectors using compatible extension modules.
The TVOC2-2-240-C version supports a broad 100–240 V AC, 50/60 Hz supply or 100–250 V DC supply and includes an HMI-COM communication interface with Modbus RTU. Its flexible architecture, multiple trip outputs and zone-selectivity capabilities make it particularly suitable for sophisticated switchboards, industrial power distribution systems and critical electrical installations.
Key Advantages
- Rapid arc-flash detection and protection for electrical switchgear.
- Can initiate a circuit-breaker trip signal in approximately 1 ms following arc-light detection.

Fast Arc-Flash Protection for Electrical Switchgear
Electrical arc faults can release extremely high levels of energy in a very short period, creating a serious hazard to personnel and potentially causing extensive damage to switchgear. The ABB TVOC-2 Arc Guard System uses optical detection to recognise the intense light associated with an arc and rapidly initiate the required breaker trip sequence.
The TVOC2-2-240-C combines high-speed arc detection with flexible detector placement, multiple trip outputs and Modbus RTU communication. Its scalable architecture allows additional detector inputs to be added using extension modules, making the system suitable for both compact switchboards and larger multi-zone electrical distribution installations.
Typical Applications
- Low-voltage switchgear and switchboards.
- Medium-voltage switchgear installations.
- Motor control centres and industrial distribution panels.
- Industrial power distribution systems.
- Critical process and manufacturing facilities.
- Electrical installations requiring rapid arc-flash fault mitigation.
