Why Choose the TE Connectivity 1SNA166547R2200 FIT-1/4-G Voltage Test Plug?
The TE Connectivity 1SNA166547R2200 is a specialised 4-pole voltage test plug designed for electrical measurement, testing, commissioning and maintenance applications. Also identified as the FIT-1/4-G, this component forms part of the established ENTRELEC ESSAILEC measuring and testing range, providing a removable interface for accessing secondary electrical circuits without unnecessarily disturbing permanent panel wiring.
The FIT-1/4-G uses a 4-pole configuration with insertion positions 1-2-3-4, distinguishing it from other ESSAILEC plug configurations with different insertion arrangements. It is designed to work with compatible ESSAILEC sockets and separately selected BRE contact pins, allowing the test connection to be configured for the requirements of the installation.
With a width of 44 mm, depth of 83.5 mm and net weight of approximately 60 g, the 1SNA166547R2200 provides a compact test interface for protection, metering and measurement systems. Its modular ESSAILEC design makes it particularly suitable for voltage transformer circuits, protection relay panels, switchgear and other installations requiring repeatable access for electrical testing.

Reliable Access for Voltage Circuit Testing
Voltage test plugs provide a controlled interface between permanently installed electrical circuits and temporary test or measurement equipment. In protection and metering installations, this approach can simplify commissioning, diagnostics and routine maintenance by providing repeatable circuit access without requiring technicians to repeatedly alter permanent field wiring.
The FIT-1/4-G forms part of the modular ESSAILEC system and provides four test positions in a defined 1-2-3-4 insertion arrangement. When combined with the appropriate ESSAILEC socket and contact pins, it provides a practical test interface for voltage transformer circuits, protection relays, metering equipment and other secondary electrical systems.
Typical Applications
- Voltage transformer secondary circuits.
- Protection relay testing and commissioning.
- Electrical energy metering systems.
- Substation protection and control panels.
- Switchgear testing and maintenance.
- Industrial voltage measurement and monitoring systems.
