The TE Connectivity PF-D-VA 1SNA166762R0100 is a professional ESSAILEC® voltage transformer test block with closed contacts, designed for measurement, protection and testing circuits in electrical switchgear and control systems. Part of the established TE Connectivity Entrelec ESSAILEC range, it provides a reliable interface for voltage transformer circuits where safe, organised testing and dependable electrical connections are required.
The PF-D-VA is configured for half-base / semi-flush mounting and uses ring-tongue connection technology. Its closed-contact configuration makes it suitable for voltage transformer applications where circuit continuity is required during normal service, while the ESSAILEC system provides convenient access for testing and measurement procedures.
Designed specifically for industrial voltage transformer applications, the PF-D-VA can be used with compatible FIP-1/4-D and FIP-1/4-G plugs. Its modular design makes it particularly suitable for switchboards, protection relay panels, metering equipment and electrical installations where routine testing and maintenance must be carried out efficiently.
Voltage transformer test blocks provide an accessible interface between instrument transformers and associated metering or protection equipment. This allows engineers and maintenance personnel to perform testing, measurement and commissioning procedures while reducing the need to disturb permanent field wiring.
The ESSAILEC range is designed for professional test and measurement applications within electrical distribution systems. The PF-D-VA combines closed contacts, ring-tongue connections and a semi-flush mounting arrangement to provide a dependable solution for voltage transformer circuits in switchgear, protection panels and industrial electrical installations.
