The TE Connectivity 1SNA166631R2600 is a PC-E-C5A-8.8 polarity test socket from the ENTRELEC ESSAILEC measuring and testing range. Designed for secondary electrical test circuits, this blue socket combines shunted contacts, a protective cover and 8.8 coding with a compact mounting format for professional metering, protection and instrumentation systems.
The PC-E-C5A-8.8 uses a C5A plug-in connection and is rated at 400 V and 8 A. ESSAILEC test blocks provide a dedicated plug-and-play interface for current and voltage measurement, monitoring, signal injection, maintenance and replacement of meters or protection relays installed in secondary transformer and sensor circuits.
Measuring approximately 74 × 50 × 40 mm, the socket can be installed on G32, TH35-7.5 and TH35-15 mounting rails in accordance with IEC 60715. Its coded interface and protection against incorrect plug insertion help provide an organised and dependable testing solution for switchgear, protection panels and industrial electrical installations.
ESSAILEC test systems are designed to simplify testing operations on secondary circuits associated with current and voltage transformers, sensors, meters and protection relays. The plug-and-socket architecture enables measurement, monitoring, injection, maintenance and equipment replacement through a dedicated interface, while the ESSAILEC coding system helps prevent connection errors between different circuits.
The TE Connectivity PC-E-C5A-8.8 combines a shunted polarity socket arrangement with a C5A connection interface and 8.8 coding. Its compatibility with G32 and TH35 mounting rails allows straightforward integration into industrial panels, switchgear and protection systems where repeatable access to electrical test circuits is required.
