The TE Connectivity 1SNA166500R0000 is an industrial current test socket designed for safe and convenient testing, measurement and isolation of current circuits in electrical protection and metering systems. Also identified as the CC-DS-VL, this component forms part of the established ENTRELEC ESSAILEC test block range, developed for applications where electrical measuring equipment must be tested or disconnected without unnecessarily disturbing permanent field wiring.
The CC-DS-VL uses a shunted current socket configuration and screw connections to provide dependable electrical contact. It is designed for base and half-base mounting and interfaces with compatible ESSAILEC plugs and accessories, providing a modular test connection system for switchgear, protection panels, substations and electrical measurement installations.
With a compact housing measuring approximately 63 × 44 × 40 mm, the 1SNA166500R0000 provides a space-efficient solution for current circuit testing. The ESSAILEC system is particularly suited to current transformer secondary circuits and other measurement applications where safe testing, commissioning and maintenance access are important.
Current test sockets provide a controlled interface between permanent electrical wiring and portable or removable test equipment. In protection and metering systems, this allows engineers to carry out commissioning, measurement and maintenance procedures while minimising the need to alter permanent panel wiring.
The CC-DS-VL forms part of the modular ESSAILEC test system and is designed specifically for current circuits. Its shunted configuration, screw connections and compatible plug system make it suitable for applications involving current transformers, protection relays, energy metering equipment and other electrical measurement systems.
