The TE Connectivity M10-I-C5A-1 (1SNA166774R0500) is a 10-point ENTRELEC ESSAILEC multicircuit test socket designed for protection, metering, measurement and electrical testing installations. Part of the established ESSAILEC test block system, it provides a structured interface between permanently wired circuits and compatible test equipment for commissioning, monitoring and maintenance.
The M10-I-C5A-1 uses a reverse-mounting configuration and 5 × 0.8 mm quick-connect terminals, providing efficient installation within compatible electrical panels. The socket is supplied with the accessories required for its mounting arrangement together with two COP-E-1 coding pins, helping provide a correctly configured connection with compatible ESSAILEC equipment.
Rated at 400 V and 8 A, the M10-I-C5A-1 is designed for demanding industrial test applications and has a short-circuit withstand capability from 25 A for 5 s to 800 A for 25 ms. The compatible FIM10-I-1 plug provides the corresponding removable test connection, while its grey housing and compact multicircuit format support organised panel construction.
ESSAILEC multicircuit test blocks provide a dedicated interface between permanently installed electrical circuits and removable test equipment. By grouping multiple test points into a purpose-designed socket and plug system, engineers can carry out commissioning, measurement and maintenance procedures through an organised interface while reducing repeated manipulation of permanent panel wiring.
The M10-I-C5A-1 combines ten test points with reverse mounting, quick-connect terminals and coded plug compatibility. When used with the corresponding FIM10-I-1 plug, it provides a practical connection system for protection, metering and monitoring panels where dependable and repeatable electrical testing is required.
