Sales of Swiss ABB arc light detector TVOC-2-240-C

Sales of Swiss ABB arc light detector TVOC-2-240-CTVOC-2-240 is an arc monitoring system from ABB brand, also known as arc protection relay. TVOC-2-240 is an arc monitoring system from ABB brand, also known as arc protection relay.

The TVOC-2 arc monitoring system adopts the famous TVOC design, focusing more on product reliability, flexibility, and simplicity. This system can provide reliable arc fault solutions for various devices, eliminate potential hazards, and protect personnel and equipment safety. Typical applications include all low-voltage switchgear and medium voltage switchgear.

System Overview: When an arc fault occurs, the response time (measured in milliseconds) is crucial and urgent. The TVOC-2 arc monitoring system can quickly detect arc faults and trip the incoming switch. It takes light as the main criterion for judgment and can cross all other protections and delays, acting instantly.

The design of the arc monitor adopts a modular concept and is suitable for all types of low and medium voltage switchgear. It has obtained functional safety (SIL-2) standard certification and complies with IEC61508 and IEC62061 standards. These standards ensure the reliability of the product. This certification is consistent with the D-level performance requirements in EN ISO13849-1. Security functions are handled by specialized hardware. In addition, the operation menus of the system, trip logs, and user-friendly interface are processed by the microprocessor. The system can be set to trip the circuit breaker based on which light sensor detects the light. This function can be set through a dip switch, and automatic reset and current sensing units can be configured. Please refer to pages 14-15 for detailed information. The energy stored in the system can support operation for 0.2 seconds after a power interruption, which is sufficient to ensure the tripping circuit operates even in the event of a short circuit fault or voltage loss. Attention: The circuit breaker still requires a backup power supply as the working power source for the trip circuit. All wiring connections can be made on the front of the arc light monitor. Plug in terminal blocks help to complete wiring before installing TVOC-2 into the switchgear. The solid-state trip contact is IGBT type, which can ensure fast and reliable trip.
