Manufacturer: ABB
Product Number: TVOC-2-240 (3BHE025541R0101)
Category: Arc Monitoring Relay
Series: ABB TVOC series
Application: Critical industrial applications requiring rapid detection and mitigation of arc faults in electrical systems
Product Description
The ABB TVOC-2-240 3BHE025541R0101 is a high-performance arc monitoring relay designed for critical industrial applications, ensuring rapid detection and mitigation of arc faults in electrical systems. As part of ABB’s advanced TVOC series, the TVOC-2-240 combines cutting-edge technology with robust construction to protect personnel, equipment, and processes from the catastrophic effects of arc flash incidents. Its modular design and versatile communication capabilities make it suitable for a wide range of industries, including power generation, manufacturing, and petrochemicals.
Technical Specifications
| Parameter | Specification |
|---|---|
| Voltage Input | 100–240 V AC/DC ±10% |
| Current Consumption | ≤1.5 W |
| Response Time | <1 ms (arc detection to breaker trip) |
| Communication Protocols | Modbus RTU, Profibus DP, Ethernet/IP |
| Optical Sensors Supported | Up to 30 (via expansion modules) |
| Operating Temperature | -25°C to +55°C |
| level of protection | IP20 (front panel), IP54 (with enclosure) |
| Certifications | CE, UL, CSA, IEC 61641 (arc flash protection) |
Key Advantages and Features
- Rapid Arc Detection: The TVOC-2-240 detects arc faults in milliseconds, significantly reducing damage compared to traditional protection systems.
- Modular Architecture: Supports hot-swappable modules for easy maintenance and scalability, with up to 30 optical sensors per system.
- Dual-Channel Protection: Combines light and current detection for enhanced reliability, minimizing false alarms.
- Remote Monitoring: Enables real-time status updates and diagnostics via integrated HMI or network interfaces.
- Energy Efficiency: Low power consumption (≤1.5 W) reduces operational costs in long-term use.
Application Areas and Case Studies
The TVOC-2-240 excels in:
- Power Generation: Protecting switchgear, transformers, and motor control centers.
- Manufacturing: Preventing arc faults in high-voltage equipment and robotic systems.
- Petrochemical: Ensuring safety in explosive environments through SIL-2 certification.
Case Study: A steel mill in Germany reduced downtime by 20% after integrating the TVOC-2-240 into its rolling mill control system. The system’s rapid fault detection and precise zone selectivity minimized damage during an arc incident, saving over €500,000 in repair costs annually.
Competitive Comparison
Compared to similar arc monitoring solutions, the TVOC-2-240 offers:
- Superior Scalability: Supports 50% more sensors than most competitors, ideal for large-scale installations.
- Faster Response: <1 ms trip time vs. typical 5–10 ms in legacy systems.
- Cost-Effective Design: Reduced hardware requirements due to integrated communication modules.
Selection Recommendations
- Compatibility: Verify PLC and breaker compatibility using ABB’s system manuals.
- Environmental Conditions: Ensure the operating temperature range (-25°C to +55°C) matches your facility’s requirements.
- Future Expansion: Plan for scalability by selecting models with expansion slots for additional sensors.
Precautions
- Installation: Follow ESD protection guidelines and secure all connections to prevent signal interference.
- Calibration: Regularly test sensors and update firmware to maintain optimal performance.
- Ventilation: Ensure adequate airflow in enclosed cabinets to prevent overheating.
- Safety Compliance: Adhere to local arc flash safety standards (e.g., NFPA 70E) during installation and maintenance.
