Why Choose the ABB TVOC-2-240 Arc Monitor?
The ABB 1SFA664001R1001 TVOC-2-240 is the main arc monitor for the ABB Arc Guard System™ TVOC-2, designed to detect the intense light associated with an internal electrical arc and initiate rapid breaker tripping. It provides high-speed arc-fault protection for switchboards and other low-voltage electrical assemblies where reducing arc duration can help limit equipment damage and improve personnel safety.
The TVOC-2-240 operates from a rated supply of 100–240 V AC, 50/60 Hz or 100–250 V DC. The main unit provides 10 optical detector inputs and can be expanded with compatible TVOC-2 extension modules when additional detector coverage is required.
This version includes one HMI and door-mounting accessories. The HMI provides system status, trip information, connected-module information, configuration details, self-diagnostic results and an error log, supporting straightforward commissioning, monitoring and fault investigation.
Key Advantages
- Rapid arc detection using optical sensors positioned throughout the protected switchgear.
- Designed to initiate a breaker trip extremely quickly when an arc event is detected.
- 10 detector inputs integrated into the main arc monitor.
- Expandable architecture supports additional optical detector inputs using compatible extension modules.
- Can trip multiple breakers and support zone-selective protection arrangements.
- Integrated HMI provides status, trip logs, diagnostics and configuration information.
- Wide-range 100–240 V AC / 100–250 V DC supply capability.
- Continuous self-supervision helps identify faults within the protection system.
Key Features
- ABB Arc Guard System™ TVOC-2 main unit.
- Model TVOC-2-240.
- Optical arc-flash detection principle.
- 10 optical detector inputs on the main unit.
- Three high-speed trip outputs for breaker tripping and zone-selective arrangements.
- Extension capability for larger switchgear installations.
- HMI supplied with the arc monitor.
- Door-mounting accessories supplied for the HMI.
- Power, trip and error indications through the HMI.
- Trip and error logging plus system self-diagnostics.
Fast Optical Arc-Fault Protection
An electrical arc can release a large amount of energy in a very short time, so reducing the time between arc initiation and breaker operation is central to arc-flash mitigation. The TVOC-2 system uses optical detectors to recognise the characteristic light produced by an arc and sends a rapid trip signal to the associated circuit breaker.
The TVOC-2-240 provides 10 detector inputs as standard and can be expanded for larger switchgear assemblies. This scalable architecture allows optical detectors to be positioned in critical compartments while the central arc monitor coordinates fast tripping and provides diagnostic information through its HMI.
Typical Applications
- Low-voltage switchboards and switchgear.
- Power distribution assemblies.
- Motor control centres.
- Industrial electrical distribution systems.
- Critical process and automation switchgear.
- Electrical installations requiring high-speed arc-fault detection.
