Why Choose the TE Connectivity FIDE-2/4-2 ESSAILEC Test Plug?
The TE Connectivity FIDE-2/4-2 1SNA166943R2700 is an orange 2-pole ESSAILEC test plug designed for use with compatible ENTRELEC test sockets in electrical protection and secondary-circuit applications. It provides a purpose-designed removable interface for test procedures involving protection relays, transformer secondary circuits and associated control equipment.
This FIDE-2/4-2 variant is supplied with 2.5 mm² BRE-T-2.5 contact pins, providing a ready-configured contact arrangement without separate coding pins. It is specifically listed for use with the DEO-E-A and DEO-D-VA ESSAILEC sockets, supporting a clearly defined combination for protection and trip-circuit test installations.
With a weight of approximately 105 g, the FIDE-2/4-2 forms part of the modular ESSAILEC platform developed for repeatable testing, measurement, monitoring, signal injection and maintenance. The plug-and-socket approach allows test equipment to interface with permanently installed secondary circuits without repeatedly altering the fixed panel wiring.

Reliable Plug-In Access for Protection Circuit Testing
The ESSAILEC system provides a defined interface between permanently wired secondary circuits and removable test equipment. In protection and trip-circuit applications, this architecture allows technicians to perform commissioning, measurement and maintenance operations through dedicated plug-and-socket combinations rather than repeatedly disconnecting fixed conductors.
The FIDE-2/4-2 is supplied with its 2.5 mm² contact pins already specified and is matched to designated DEO socket configurations. This makes it a practical choice where a repeatable and clearly identifiable removable test connection is required in switchgear, protection panels and substation control equipment.
Typical Applications
- Protection relay testing and commissioning.
- Trip and protection secondary circuits.
- Transformer and sensor secondary circuits.
- Substation control and protection panels.
- Industrial switchgear assemblies.
- Electrical metering and monitoring equipment.
- Routine maintenance and diagnostic testing.
- ESSAILEC installations using compatible DEO test sockets.
