1sna166525r1400 – current test plug 2 x 4 pole

Why Choose the TE Connectivity FIC-2/4-1 Current Test Plug?

The TE Connectivity FIC-2/4-1 (1SNA166525R1400) is a specialised 2 × 4-pole current test plug designed for safe and efficient testing of electrical protection, metering and current transformer circuits. Part of the established TE Connectivity ENTRELEC ESSAILEC range, it provides a plug-in interface that allows engineers to perform testing, measurement and maintenance operations without unnecessarily disturbing permanent installation wiring.

The FIC-2/4-1 features a short monobloc cover, two coding pins and eight locking pins, providing secure mechanical engagement and helping prevent incorrect connection between different test circuits. Its 2 × 4-pole arrangement enables simultaneous access to multiple circuit connections, making it particularly useful in protection relay, metering and secondary current transformer applications.

With a rated voltage of 400 V and compact dimensions of approximately 63 × 44 × 115 mm, the FIC-2/4-1 is designed for professional power distribution and automation environments. BRE-C contact pins are ordered separately, allowing the plug to be configured to suit the required wiring arrangement.

Reliable Testing for Current Transformer and Protection Circuits

ESSAILEC test blocks are designed to simplify electrical testing operations including current and voltage measurement, monitoring, injection, commissioning and the servicing or replacement of meters and protection relays. The plug-and-socket system provides engineers with an accessible test interface while helping minimise disruption to permanently installed secondary circuits.

The FIC-2/4-1 is specifically designed for current testing applications and forms part of the modular ESSAILEC system. Its coding and locking features improve connection security, while the configurable BRE-C contact arrangement allows the plug to be adapted to the requirements of compatible ESSAILEC current sockets.
