The TE Connectivity CC-E-VA-6.6 1SNA166625R2000 is a robust ESSAILEC current test socket designed for current-transformer secondary circuits, electrical metering and protection-system testing. Part of the established TE Connectivity ENTRELEC ESSAILEC series, it provides a secure interface for measurement and commissioning work while helping maintain the continuity and safety of current circuits.
The CC-E-VA-6.6 incorporates an automatic short-circuiting arrangement specifically intended for current-transformer applications. The circuit is automatically shorted during plug insertion and closes automatically again when the plug is removed, helping protect CT secondary circuits during testing and maintenance procedures.
Rated at 15 A with a 400 V rated voltage, the 1SNA166625R2000 features green polycarbonate insulation and ring-tongue connections. Its compact 50 × 74 × 57 mm format and compatibility with G32 and TH35 DIN rails make it suitable for integration into industrial switchboards, protection panels and metering cabinets.
Current-transformer secondary circuits require particular care during testing because an open secondary circuit can create unsafe operating conditions. The ESSAILEC system addresses this requirement through a controlled plug-and-socket arrangement that automatically manages the current circuit as test equipment is connected or disconnected.
The CC-E-VA-6.6 is therefore well suited to protection and metering installations where technicians need repeatable access for commissioning, relay testing, meter verification and scheduled maintenance without unnecessarily disturbing permanent panel wiring.
