The TE Connectivity PO-D-VA 1SNA166760R1300 is a professional ESSAILEC voltage transformer test socket with open contacts, designed for testing, measurement and maintenance of secondary voltage circuits. Part of the established TE Connectivity ENTRELEC ESSAILEC measuring and testing range, it provides a controlled plug-in interface for applications involving voltage transformers, meters and protection relays.
This blue polarity socket uses dependable ring-tongue connections and is designed for half-base mounting. Its open-contact configuration enables the associated circuit to be opened during testing, while the ESSAILEC plug-and-socket architecture allows engineers to perform measurement, monitoring, injection and maintenance operations without repeatedly disturbing permanent panel wiring.
With a rated current of 8 A and rated voltage of 400 V, the PO-D-VA is suited to demanding protection and instrumentation applications. The socket has a net weight of approximately 170 g and is compatible with the CPP-2 protecting lid and selected ESSAILEC pre-wired test plugs, including the COR-P-R1-8.8.
ESSAILEC test blocks are designed to simplify measurement, voltage monitoring, injection, commissioning, repair and replacement operations in secondary circuits associated with voltage transformers, sensors, meters and protection relays. Their dedicated plug-and-socket architecture provides repeatable test access while helping maintain organised permanent wiring.
The PO-D-VA combines open contacts with robust ring-tongue field termination and blue polarity identification. This configuration makes it particularly suitable for voltage transformer installations where engineers need a dependable interface for testing and maintenance within protection panels, switchgear and substation equipment.
