The TE Connectivity CC-R-VA (1SNA166523R1200) is a specialised ESSAILEC current test socket designed for safe, reliable testing and measurement circuits in electrical protection, metering and current transformer installations. Part of the established TE Connectivity ENTRELEC ESSAILEC test block range, this socket provides a dedicated interface for testing equipment while helping simplify commissioning and maintenance operations.
The CC-R-VA is specifically configured for rack mounting and uses ring-tongue connections for secure permanent wiring. ESSAILEC test blocks are widely used in secondary current transformer circuits, where their modular connection system allows measurement and test equipment to be connected without unnecessarily disturbing permanent installation wiring.
Designed for professional electrical installations, the 1SNA166523R1200 provides a robust fixed socket interface compatible with selected ESSAILEC accessories and test plugs. Its rack-mounted format makes it particularly suitable for protection and control systems, switchgear, substations, metering panels and other applications requiring accessible current testing points.
ESSAILEC test blocks provide dedicated interfaces between permanently installed measurement circuits and portable or fixed testing equipment. In current transformer applications, this helps engineers perform commissioning, measurement and maintenance procedures through an organised test interface rather than repeatedly disturbing permanent field wiring.
The CC-R-VA rack-mounted socket is designed for integration into professional protection and control systems where dependable test access is required. Its ring-tongue connection arrangement provides secure wiring, while compatibility with dedicated ESSAILEC plugs and accessories supports a structured approach to electrical testing and maintenance.
