Why Choose the TE Connectivity FIP-1/4-D ESSAILEC Test Plug?
The TE Connectivity FIP-1/4-D (1SNA166555R2200) is a specialised 4-pole ESSAILEC test plug designed for voltage transformer, protection, metering and electrical test circuits. Part of the established TE Connectivity ENTRELEC ESSAILEC range, it provides a secure plug-in interface for testing, measurement, commissioning and maintenance operations within industrial and utility electrical systems.
The FIP-1/4-D uses a 4-pole 01-02-03-04 insertion arrangement and is supplied with four locking pins to provide secure mechanical engagement with compatible ESSAILEC sockets. Its blue colour provides clear identification within test systems, while the modular design enables engineers to configure dedicated testing connections without unnecessarily disturbing permanent field wiring.
Designed for professional protection and measurement installations, the FIP-1/4-D is compatible with selected ESSAILEC sockets including PF-E-VA, PF-DS-VL and PF-D-VA. The required BRE contact pins are ordered separately, allowing the test plug to be configured for the specific electrical connection requirements of the application.

Reliable Testing for Protection and Measurement Systems
ESSAILEC test blocks provide dedicated interfaces between permanently installed electrical circuits and testing or measurement equipment. The system allows engineers to carry out commissioning, monitoring, measurement and maintenance procedures through an organised plug-and-socket interface, reducing the need to disconnect permanent field wiring.
The FIP-1/4-D is particularly suited to voltage transformer and protection applications requiring a compact four-pole test connection. Its locking arrangement helps maintain secure engagement during testing, while separately selected BRE contact pins allow the plug to be configured for compatible ESSAILEC installations.
Typical Applications
- Voltage transformer secondary circuits.
- Protection relay testing and commissioning.
- Electrical energy metering systems.
- Substation protection and control panels.
- Switchgear testing and maintenance.
- Voltage measurement and monitoring circuits.
- Industrial and utility power distribution systems.
