The TE Connectivity 1SNA166513R1000, manufacturer designation M10-D-C5A, is a 10-point multicircuit ESSAILEC test socket designed for half-base mounting in electrical measurement, metering and protection systems. It provides the fixed socket interface for the compatible FIM10-1 test plug, allowing multiple secondary circuits to be connected through a coordinated plug-and-socket test system.
The M10-D-C5A uses C5A quick-connect technology and is designed for ESSAILEC applications involving current and voltage measurement, monitoring, test injection and servicing of meters or protection relays. The system's plug-and-play architecture allows testing to be carried out while minimising disturbance to permanent field wiring.
The grey socket provides 10 connection points in a compact housing measuring approximately 22 × 63 × 40 mm. It can be installed with G32, TH35-7.5 and TH35-15 DIN rail arrangements and is supplied with the accessories required for its half-base mounting configuration, including ESSAILEC coding components.
ESSAILEC test blocks are designed to simplify testing operations in the secondary circuits of current and voltage transformers and sensors. When paired with the compatible FIM10-1 plug, the M10-D-C5A provides a removable test interface for measurement, monitoring, signal injection, meter servicing and protection relay maintenance.
The ESSAILEC system incorporates features intended to improve testing efficiency and connection security, including circuit coding and protection against reverse plug insertion. In current-testing configurations, the system's contact-before-disconnection principle supports automatic current-transformer secondary short-circuiting during the testing sequence.
