£22.91
The TE Connectivity 1SNA166529R2000 is an FIC-2/4-R current test plug from the ENTRELEC ESSAILEC measuring and testing range. Designed specifically for current-testing circuits, this plug features a 2 × 4-pole configuration and rack/back-panel mounting arrangement for use with compatible ESSAILEC current sockets.
ESSAILEC test systems provide a structured method for performing measurement, monitoring, injection, maintenance and replacement operations on secondary circuits associated with current transformers, current sensors, meters and protection relays. The FIC-2/4-R enables simultaneous connection across multiple current circuits while maintaining a dedicated plug-and-socket test interface.
The FIC-2/4-R is supplied with 2 coding pins and 8 locking pins, helping ensure correct mechanical positioning and secure engagement with the compatible socket assembly. Contact pins from the BRE-C range are selected separately according to the required conductor connection, providing flexibility when configuring the test plug for a particular installation.
ESSAILEC test blocks are engineered to simplify testing operations on secondary circuits associated with current transformers, sensors, meters and protection relays. The modular plug-and-socket architecture provides technicians with a dedicated interface for measurement, monitoring, signal injection, maintenance and equipment replacement instead of relying on temporary or improvised wiring connections.
The TE Connectivity FIC-2/4-R extends this concept to a 2 × 4-pole rack-mounted current interface. When configured with the appropriate BRE-C contact pins and compatible CC-R-VA socket, it provides a purpose-built connection point for multi-circuit current testing in switchgear, protection panels, substations and industrial power distribution equipment.
