Features:
- Wide supply voltage range (100-240 V AC/DC) for global compatibility with different power systems.
- 3 NO and 3 CO auxiliary contacts for flexible integration with protection relays and control circuits.
- DIN rail or wall mounting capability for easy installation in new or existing switchgear panels.
The 1SFA664001R1001 TVOC-2-240 is a critical component of ABB's Arc Guard System, designed to detect dangerous arc flashes in low voltage switchgear. Arc faults release intense light, heat, and pressure waves that can cause severe injury to personnel and catastrophic damage to equipment. This monitor detects the arc event and triggers a fast shutdown—typically within milliseconds—to extinguish the arc before it causes harm. For facilities operating switchgear in power plants, data centers, industrial plants, and commercial buildings, this arc monitor is an essential safety device. Its 100-240 V AC/DC supply voltage works with virtually any global power system.
The 1SFA664001R1001 TVOC-2-240 provides three normally open (NO) and three changeover (CO / SPDT) auxiliary contacts. These contacts can be wired to circuit breakers, contactors, protection relays, or PLCs to initiate fast tripping when an arc is detected. The changeover contacts offer both normally open and normally closed connections in a single contact, reducing wiring complexity. For existing switchgear retrofits, the compact DIN rail mounting (35 mm standard rail) allows installation without major panel modifications. The device also supports wall mounting for non-rail applications. Power loss is minimal—1 W standby, 5 W active—reducing heat load in enclosed cabinets.
The 1SFA664001R1001 TVOC-2-240 meets RoHS requirements (RoHS date 1009) and is classified under WEEE Category 5 (Small Equipment). Its ETIM codes are EC001444 (Insulation and earth fault monitoring relay) and EC002911 (Arc detection system). The UNSPSC code is 43171815. ABB provides comprehensive documentation: data sheet (1SFC170001C0201), CE declaration (1SFA1-99), environmental information (1SFC170003D0201), instructions (1SFC170011M0201), and RoHS information (1SFC170002D0201). For arc flash protection in low voltage switchgear, this monitor is a proven, standards-compliant solution.
The 1SFA664001R1001 TVOC-2-240 ABB Arc Monitor may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Power Facilities: High and low voltage switchgear, substations, power distribution centers.
- Critical Infrastructure: Hospitals, data centers, large commercial buildings, airports, and schools.
- Industrial Processes: Chemical industry, steel mills, paper mills, wind power plants, and oil drilling platforms.
- Transportation: Trains (to prevent DC converter fires caused by dust), cruise ships, and merchant vessels.
- Rapid Response: The standalone monitor's response time is less than 1 millisecond (ms). When paired with the ABB Emax 2 circuit breaker, the total arc clearing time is only about 50 milliseconds, while traditional circuit breakers without arc protection may take more than 1 second.
- High Reliability (SIL-2): Compliant with IEC 61508 and IEC 62061 SIL-2 functional safety certifications, ensuring accurate action at critical moments.
- Intelligent Diagnosis and Communication:
Supports Modbus RTU protocol for real-time exchange of status data with remote control stations.
- HMI (Human Machine Interface): Can be installed on cabinet doors, providing full-text display and timestamped error logs.
- Equipment Retrofitting: Add arc flash protection to aging switch cabinets to extend their service life and meet modern safety standards.
- Personnel Protection: Ensure operators are protected from arc flash even when switch cabinet doors are open.
- Remote expansion and distributed deployment of I/O links in power plant automation control systems.
- Multi-Zone Isolation: A single TVOC-2 unit can manage up to 30 light sensors divided into 3 independent selective zones, cutting off only the affected areas to minimize the scope of power outages.
