Why Choose the ABB TVOC-2-48 Arc Monitor?
The ABB 1SFA664001R1002 TVOC-2-48 is an Arc Guard System™ arc monitor designed for rapid optical detection of electrical arc faults in switchgear and switchboard assemblies. By detecting the intense light generated by an arc and initiating a fast breaker-trip signal, the system helps reduce arc duration and limit the resulting damage to electrical equipment.
The TVOC-2-48 is the 24–48 V DC supply version of the TVOC-2 arc monitor. Its main unit provides 10 optical detector inputs for monitoring multiple switchgear compartments, with expansion capability available through compatible ABB TVOC-2 modules where additional detector coverage is required.
The unit incorporates three high-speed trip outputs and supports scalable arc-protection arrangements for professional power-distribution systems. An HMI provides system status, trip information, configuration and diagnostic information, helping simplify commissioning, supervision and investigation following an arc event.

Fast Optical Arc-Fault Protection
Electrical arcs can release substantial energy in a very short period, making rapid fault detection and breaker operation important in arc-protection systems. The TVOC-2 system uses optical detectors positioned within the protected switchgear to identify the characteristic light generated by an arc and communicate the event to the central arc monitor.
With 10 optical detector inputs and three high-speed trip outputs, the TVOC-2-48 provides a scalable foundation for protecting multiple switchgear compartments. Its 24–48 V DC supply range makes this version suitable for installations where low-voltage DC control power is available.
Typical Applications
- Low-voltage switchboards and switchgear.
- Power-distribution assemblies.
- Motor control centres.
- Industrial electrical distribution systems.
- Critical process and automation switchgear.
- Installations requiring high-speed optical arc-fault detection.
