The TE Connectivity CC-D-VA 1SNA166738R0100 is an industrial ESSAILEC current test socket designed for current transformer secondary circuits, electrical protection systems and metering applications. Part of the established TE Connectivity ENTRELEC ESSAILEC measuring and testing range, it provides a dedicated connection point for safe, organised testing and maintenance of current circuits.
The CC-D-VA is designed for base or half-base mounting and uses ring-tongue connections for dependable permanent wiring. This arrangement makes the socket particularly suitable for protection and measurement installations where robust conductor termination and repeatable access to secondary current circuits are required.
With a green coding colour, approximately 90 g product weight and compatibility with the CPC-1 protective lid and selected ESSAILEC current test plugs, the CC-D-VA provides a practical test interface for switchgear, substations, relay panels and industrial metering systems.
ESSAILEC current test blocks provide dedicated interfaces for secondary current circuits associated with current transformers, protection relays and measuring equipment. They allow engineers to connect suitable testing equipment during commissioning, fault finding and scheduled maintenance while reducing the need to alter permanent panel wiring.
The CC-D-VA combines ring-tongue termination with a base or half-base mounting arrangement and compatibility with modular ESSAILEC accessories. This makes it particularly suitable for organised protection and metering installations where dependable, repeatable test access is essential.
