ABB TVOC-2-240 1SFA664001R1001 Arc Guard System
Product Overview
The ABB TVOC-2-240 1SFA664001R1001 is a high-performance arc protection relay designed to detect and mitigate electrical arc faults in industrial switchgear and power distribution systems. As a core component of ABB’s Arc Guard System™, it combines optical and optional current sensing technologies to provide millisecond-level protection for personnel and equipment, significantly reducing downtime and damage caused by arc flash incidents. The TVOC-2-240 is certified for ATEX/IECEx Zone 2 hazardous environments and SIL 2 compliance, making it ideal for industries such as oil & gas, chemical processing, and power generation where safety and reliability are paramount .
Key attributes include a modular architecture supporting up to 30 optical detectors via two extension units, ensuring comprehensive coverage of complex switchgear configurations. Its detachable full-text HMI enables real-time status monitoring, fault logging, and parameter configuration, while zone-selective trip outputs allow precise isolation of faulted sections. The TVOC-2-240 operates on a wide voltage range (100–240 V AC/DC or 100–250 V DC) and integrates seamlessly with ABB’s Ability™ EDCS and Ekip Connect 3 configuration tools, enhancing system interoperability .

Key Features and Advantages
Dual-Mode Arc Detection
The TVOC-2-240 employs optical detection as its primary method, using 10 detector inputs to sense arc light within milliseconds. For environments prone to false triggers from external light sources, an optional Current Sensing Unit (CSU-2) monitors fault currents, ensuring reliable operation. This dual-mode approach reduces nuisance tripping while maintaining ≤1 ms response time .
Modular Scalability
With support for up to 30 detectors via two extension units, the TVOC-2-240 adapts to large-scale switchgear installations. Its zone-selective trip outputs enable targeted circuit breaker tripping, minimizing downtime by isolating faults without disrupting unaffected areas. The system’s tool-free wiring and mechanical keying simplify installation and prevent incorrect module insertion .
Safety Compliance
Certified to SIL 2 (IEC 61508) and ATEX/IECEx Zone 2, the TVOC-2-240 meets rigorous safety standards for hazardous environments. Its self-diagnostic capabilities continuously monitor sensor integrity and communication paths, while the detachable HMI provides real-time fault logging and status updates. This ensures compliance with industry regulations and enhances operational resilience .
Environmental Resilience
Designed for harsh industrial conditions, the TVOC-2-240 operates reliably from -25°C to +55°C and withstands high humidity (5–95% non-condensing). Its IP20-rated housing and corrosion-resistant materials ensure long-term durability in offshore platforms, chemical plants, and other demanding settings .
