The TE Connectivity FIC-2/1-1 1SNA166819R2300 is a compact ESSAILEC current test plug designed for safe and convenient access to current-transformer secondary circuits used in electrical metering, measurement and protection systems. Part of the established TE Connectivity ENTRELEC ESSAILEC series, it provides a plug-in solution for commissioning, calibration, monitoring and maintenance procedures.
The FIC-2/1-1 is a 1-pole plug equipped with two 2.5 mm² BRE-C-2.5 contact pins. Unlike larger configurable ESSAILEC plugs whose contact pins are selected separately, this model is supplied with its two contact pins fitted and does not include coding pins. Its straightforward configuration makes it particularly useful where a compact current-circuit test connection is required.
Designed for the ESSAILEC current range, the 1SNA166819R2300 works with a selection of compatible CC-series sockets and supports the make-before-break testing concept used for current-transformer circuits. The plug weighs approximately 27 g and provides a practical interface for engineers carrying out measurement, calibration and protection-relay testing in switchboards and power-system installations.
ESSAILEC current test blocks are designed around a make-before-break principle for current-transformer applications. With a compatible socket, the circuit is automatically managed during plug insertion and removal, supporting safe and controlled measurement, calibration and maintenance procedures on current-transformer secondary circuits.
The FIC-2/1-1 provides a compact plug interface for this modular system. Its factory-fitted BRE-C-2.5 contact pins simplify configuration, while compatibility with CC-E-VA, CC-E-VA-6.6, CC-D-VA, CC-R-VA and other ESSAILEC current sockets makes it suitable for a broad range of industrial test-block installations.

The FIC-2/1-1 is an ESSAILEC current test plug used for measurement, calibration, commissioning and maintenance of current-transformer secondary circuits and associated metering or protection equipment.
The FIC-2/1-1 is a 1-pole test plug equipped with two contact pins.
Yes. This model is supplied with two BRE-C-2.5 contact pins for 2.5 mm² connections, so these contacts do not need to be selected separately.
No. The FIC-2/1-1 is supplied without coding pins, distinguishing it from several larger configurable ESSAILEC plug variants.
The plug is compatible with several ESSAILEC current sockets, including CC-E-VA, CC-E-VA-6.6, CC-E-VA-R2-6.6, CC-S-INF-VL-6.6, CC-D-VA, CC-TH35-VL-6.6, CC-R-VA and CC-I-VA-2.
TE Connectivity ENTRELEC ESSAILEC components provide a proven modular approach to current-transformer measurement and testing, helping electrical engineers carry out commissioning, calibration and maintenance efficiently while reducing disturbance to permanent secondary-circuit wiring.
