ABB  1SFA664001R1001 TVOC-2-240

The ABB TVOC-2-240 (1SFA664001R1001) is the main arc monitor unit of the ABB Arc Guard System™, a high-speed optical arc flash detection system designed for low and medium voltage switchgear and motor control centers . This unit uses highly sensitive fiber-optic light sensors to detect the intense ultraviolet and visible light emitted by a fault arc .

It features a modular design that supports up to 10 light detectors on the base unit, expandable to 30 with extension units, and provides zone selectivity to isolate specific switchgear compartments . The unit can be wall-mounted or installed on a DIN rail, and includes an integrated HMI (Human Machine Interface) that can be mounted on the cabinet door for local operation, diagnostics, and event logging .

FAQ

Q1. What is ABB known for in the industrial automation industry?
ABB is a global leader in power and automation technologies . The company is renowned for its comprehensive portfolio of industrial drives (ACS series), robotics, distributed control systems (800xA), and PLC systems (AC500). ABB products are widely used across power generation, oil and gas, chemical manufacturing, mining, and heavy industry applications .

Q2. Are ABB products compatible with each other across different series?

Generally, yes. ABB designs its products with backward and cross-series compatibility in mind. For example, the KVC758A board is specifically designed for ACS5000 drives but is also compatible with ACS800 and ACS880 cabinets . Similarly, ABB's Advant OCS 800xA DCS systems integrate with various ABB drive platforms, allowing for seamless system expansion and upgrades .

Q3. What makes ABB products suitable for harsh industrial environments?

ABB products are engineered with industrial-grade specifications including :

Wide operating temperature ranges (e.g., -40°C to +70°C for the KVC758A);

High electrical isolation ratings (520 VDC or higher) to protect against voltage transients and ground loops;

Electromagnetic resilience to withstand noisy industrial environments;

Robust construction with protection against dust, moisture, and vibration;

Built-in protection mechanisms including overvoltage and overcurrent safeguards.
