Why Choose the TE Connectivity PC-D-VA 1SNA166764R0300 ESSAILEC Voltage Test Socket?
The TE Connectivity PC-D-VA 1SNA166764R0300 is a specialist ESSAILEC voltage-transformer test socket designed for electrical measurement, metering and protection circuits. Part of the established TE Connectivity ENTRELEC ESSAILEC series, it provides a dedicated interface for testing and maintenance of secondary voltage circuits without repeatedly disturbing permanent installation wiring.
The PC-D-VA uses short-circuited contacts and ring-tongue terminations in a base / half-base mounting configuration. This combination provides secure permanent conductor termination while allowing compatible ESSAILEC test equipment to be connected during commissioning, meter verification, protection-relay testing and routine maintenance.
The 1SNA166764R0300 is identified by its blue body and weighs approximately 115 g. Its modular design is compatible with selected ESSAILEC accessories and pre-wired test leads, making it a practical component for switchboards, protection cabinets and industrial metering installations where reliable voltage-circuit test access is required.

Reliable Voltage-Transformer Testing for Metering and Protection Systems
ESSAILEC measuring and testing blocks are designed to provide controlled access to secondary electrical circuits during commissioning, diagnostics and maintenance. In voltage-transformer applications, the PC-D-VA provides the fixed socket interface through which compatible test equipment can be connected for measurement and verification procedures.
This modular approach is particularly useful in installations containing electricity meters, measurement equipment and protection relays that require periodic inspection or testing. By providing a dedicated test interface, the ESSAILEC system helps reduce repeated manipulation of permanent wiring and supports organised, repeatable maintenance procedures.
Typical Applications
- Voltage-transformer secondary circuits.
- Electrical metering and measurement systems.
- Protection relay testing and commissioning.
- Industrial switchboards and control panels.
- Substation protection and instrumentation systems.
- Power distribution monitoring installations.
- Routine electrical testing and maintenance.
