Why Choose the TE Connectivity DEO-D-VA ESSAILEC Trip Test Socket?
The TE Connectivity DEO-D-VA 1SNA166874R2200 is an ENTRELEC ESSAILEC trip-range test socket designed for controlled testing of secondary electrical circuits in protection, measurement and switchgear applications. Its orange body identifies it as part of the ESSAILEC trip range, providing clear visual differentiation within multi-function test installations.
The DEO-D-VA features open contacts, half-base mounting and rear ring-tongue connections. Rated at 8 A and 400 V, it provides a robust fixed connection point for test procedures associated with protection relays and secondary transformer or sensor circuits while integrating with the modular ESSAILEC plug-and-socket system.
Designed for professional electrical panels, the DEO-D-VA can be used with the FIDE-2/4 ESSAILEC plug and CPDE-2 protective cover. The socket is supplied with the accessories required for its mounting arrangement together with two COP-E-1 coding pins, helping establish a correctly configured and identifiable test interface.

Reliable Access for Trip and Protection Circuit Testing
ESSAILEC test blocks provide a dedicated interface for operations including current and voltage measurement, monitoring, signal injection and the maintenance or replacement of meters and protection relays installed in secondary transformer and sensor circuits. The plug-and-socket architecture allows engineers to perform structured test procedures without repeatedly altering permanent panel wiring.
The DEO-D-VA is specifically configured for the ESSAILEC trip range. Its open contacts provide the circuit behaviour required for applicable trip and protection testing procedures, while the orange identification, half-base mounting, secure ring-tongue terminations and coding system support clear and repeatable operation within complex protection panels.
Typical Applications
- Protection relay trip circuits.
- Secondary transformer and sensor circuits.
- Protection relay testing and commissioning.
- Substation protection and control panels.
- Industrial switchgear assemblies.
- Electrical metering and monitoring installations.
- Power distribution protection systems.
- Routine maintenance and diagnostic test equipment.
