Why Choose the TE Connectivity CC-E-VA-ICE-6.6 1SNA166678R1500 ESSAILEC Current Test Socket?
The TE Connectivity CC-E-VA-ICE-6.6 1SNA166678R1500 is a specialist ESSAILEC current test socket designed for testing and measurement on current-transformer secondary circuits. Part of the established TE Connectivity ENTRELEC ESSAILEC series, this ICE-specific socket provides a dependable plug-in interface for commissioning, measurement, monitoring and maintenance operations in electrical protection and metering systems.
The CC-E-VA-ICE-6.6 is designed for front-panel flush mounting and uses rear screw connections for cable-lug terminations. Its current-circuit architecture incorporates make-before-break contact operation, an important feature for current-transformer applications where maintaining a controlled secondary circuit during test-plug insertion is essential.
With its dedicated 6.6 coding configuration, the 1SNA166678R1500 helps ensure that the correct test plug is connected to the appropriate circuit. The ESSAILEC plug-and-socket system enables straightforward test access while reducing the need to disconnect permanent panel wiring, making it particularly valuable in protection, metering and power-distribution installations.

Reliable Current-Transformer Testing and Measurement
Current-transformer secondary circuits require carefully controlled test procedures because interrupting the secondary circuit while the transformer is energised can create hazardous voltages. The ESSAILEC system is specifically engineered to simplify access to these circuits, and the make-before-break contact arrangement of the CC-E-VA-ICE-6.6 supports controlled circuit handling as compatible test equipment is connected.
ESSAILEC test blocks allow technicians to carry out current and voltage measurement, monitoring, signal injection, meter maintenance and protection-relay servicing through a modular plug-and-socket interface. This reduces unnecessary disturbance of permanent wiring and helps make repetitive commissioning and maintenance operations more efficient.
Typical Applications
- Current-transformer secondary circuits.
- Protection relay testing and commissioning.
- Electrical metering installations.
- Current measurement and monitoring systems.
- MV and HV switchgear protection panels.
- Power distribution and substation control panels.
- Meter and protection-relay maintenance.
