Product Overview

The ABB 1SFA664003R1060 is the TVOC-2-DP6 detector, an optical detector designed for use with the ABB Arc Guard System™ TVOC-2. The detector forms part of the optical detection architecture of the TVOC-2 Arc Monitor and is intended to identify the intense light associated with an electrical arc inside an electrical installation. The model is identified by ABB as TVOC-2-DP6 and is supplied with a 6 m detector cable, providing flexibility when positioning the detector within switchgear and other electrical equipment.

In an arc monitoring application, the detector is positioned so that an electrical arc can be detected within the protected area. The optical detector is connected to the appropriate detector input of the TVOC-2 Arc Monitor or an applicable extension module. When the detection conditions configured in the Arc Guard System are fulfilled, the monitoring system can initiate the configured trip response through its associated output circuits. This arrangement allows the optical detector to operate as one element of a coordinated arc protection system rather than as an independent protection relay.

The 1SFA664003R1060 identification is important when selecting a replacement detector or configuring a TVOC-2 installation because ABB offers several detector versions with different cable lengths. The DP6 version specifically represents the 6 m cable configuration. This makes the model suitable for installations where the distance between the detector location and the TVOC-2 monitoring equipment requires additional cable length compared with shorter detector variants.

Optical Detection for the TVOC-2 System

The operating principle of the TVOC-2 Arc Guard System is based on rapid detection of an electrical arc. An arc produces a strong optical signal, and the optical detectors provide the interface between the protected electrical area and the Arc Monitor. The detector therefore plays a critical role in transferring optical detection information to the central monitoring unit.

The ABB 1SFA664003R1060 is designed specifically for the TVOC-2 system. It is not simply a general-purpose light sensor; its product designation and system compatibility identify it as a dedicated TVOC-2 detector. Correct compatibility between the detector, Arc Monitor, and any extension modules is therefore an important consideration during system planning and installation.

The detector cable length of 6 m provides a practical installation range for electrical cabinets and switchgear arrangements where the detector cannot be located immediately beside the monitoring unit. Cable length selection should be considered together with the physical layout of the protected equipment, the position of the Arc Monitor, and the detector input arrangement used by the TVOC-2 system.

Technical Characteristics

ABB identifies the product as TVOC-2-DP6, with product ID 1SFA664003R1060. The product name is Detector, and the main product type is TVOC-2. The detector is suitable for the TVOC-2 Arc Monitor and belongs to the Arc Monitor product class. Its specified detector cable length is 6 m.

The published product dimensions are approximately 350 mm in width, 20 mm in height, and 300 mm in depth, while the product net weight is approximately 0.06 kg. These physical characteristics are useful when planning cabinet space, cable routing, and component placement. The product documentation also identifies the detector as part of the TVOC-2 family and provides technical documentation associated with the system.

The operating ambient temperature specified for the detector is -25 °C to +70 °C. This environmental range supports applications in a variety of industrial electrical environments, although the complete system installation must always be evaluated according to the environmental requirements of the specific application and all applicable installation instructions.

System Integration

The ABB TVOC-2 architecture can accommodate multiple optical detectors through the available detector inputs and optional extension modules. The 1SFA664003R1060 can therefore be incorporated into a larger detection arrangement when the protected electrical installation requires more than one optical detection point.

According to the TVOC-2 installation documentation, the Arc Monitor provides detector inputs and optional connections for extension modules. Optical detectors are connected to the designated detector inputs, while the Arc Monitor processes the detection signals and provides the configured trip and signal functions. This allows individual detector locations to be associated with different breaker trip arrangements according to the system configuration.

The TVOC-2 system also supports configuration through DIP switches. Depending on the selected configuration, detector inputs can be assigned to specific trip contacts. This functionality can be useful in switchgear installations where different sections or feeders require different trip responses. The actual configuration should always follow the electrical design and the instructions applicable to the installed TVOC-2 system.

Typical Industrial Applications

The ABB 1SFA664003R1060 can be used in electrical installations where optical arc detection is required as part of a TVOC-2 Arc Guard System. Typical application environments include industrial switchgear, power distribution equipment, electrical control assemblies, and other installations where rapid detection of an internal electrical arc is an important part of the protection strategy.

In a switchgear cabinet, the detector can be positioned according to the protection design so that the relevant compartment or electrical area is within its intended detection field. Several detectors can be arranged throughout an installation to provide coverage of multiple compartments or sections. The 6 m cable version can be particularly useful when the physical distance between a detection location and the central Arc Monitor requires a longer connection.

The detector is also relevant to system maintenance and engineering work involving existing TVOC-2 installations. When identifying a detector for an established system, the product number, detector type, cable length, and compatibility with the installed Arc Monitor should be checked carefully. The model number 1SFA664003R1060 distinguishes the DP6 version from other TVOC-2 detector variants.

Installation Considerations

Installation of the TVOC-2 system should be performed by appropriately authorized and trained personnel in accordance with applicable electrical regulations and the manufacturer’s installation documentation. Before electrical connections are made, the relevant supply circuits must be made safe according to the installation procedure.

Detector positioning is an important part of the overall system design. The detector should be installed in the location specified by the protection concept so that the optical signal produced by a potential arc can be detected effectively. Cable routing should also be planned to avoid unnecessary mechanical stress and to maintain an organized connection between the detector and the appropriate TVOC-2 input.

The detector should be connected to the designated TVOC-2 detector input or compatible extension module. After installation, the complete Arc Guard System should be configured according to the required trip arrangement and system design. The detector itself should not be considered separately from the Arc Monitor because the detection function and subsequent protection response depend on the complete system architecture.

Selection and Identification

ABB provides multiple TVOC-2 detector options distinguished primarily by cable length. The product family includes versions such as DP1, DP2, DP4, DP6, DP8, DP10, DP15, DP20, DP25, and DP30, corresponding to different detector cable lengths. Within this range, the DP6 designation identifies the 6 m version. Therefore, 1SFA664003R1060 should be selected when the required TVOC-2 detector configuration is the DP6 type.

For technical identification, several details can be used together: ABB as the manufacturer, TVOC-2-DP6 as the extended product type, 1SFA664003R1060 as the product ID, and 6 m as the detector cable length. Using the complete product number is recommended when documenting equipment, preparing technical specifications, or identifying components in an existing electrical protection system.
