Why Choose the TE Connectivity M10-P-C5A ESSAILEC Test Socket?
The TE Connectivity M10-P-C5A 1SNA166772R0300 is a 10-position ESSAILEC multicircuit test socket designed for extension mounting in professional electrical measurement and protection systems. Part of the established ENTRELEC ESSAILEC range, it provides a convenient connection interface for testing secondary circuits associated with current and voltage transformers, meters and protection relays.
The M10-P-C5A uses 5 × 0.8 mm quick-connect terminals and is rated at 8 A and 400 V. Its extension-mounting configuration provides an alternative installation arrangement within the ESSAILEC multicircuit family, while the grey housing and dedicated coding system support organised identification and correct mating of test components.
ESSAILEC multicircuit test blocks are designed to simplify measurement, monitoring, signal injection, commissioning and maintenance procedures. The M10-P-C5A can be used with the compatible FIM10-1 plug, providing a plug-and-play interface that enables engineers to access test circuits without repeatedly disturbing permanently installed wiring.
