1sna166776r0700 – m20-p-c5a
TE Connectivity M20-P-C5A 1SNA166776R0700 is an ENTRELEC ESSAILEC 20-point multicircuit test socket with clip connections for electrical measurement, monitoring, protection, commissioning and maintenance applications.
Why Choose the TE Connectivity M20-P-C5A ESSAILEC Multicircuit Socket?
The TE Connectivity M20-P-C5A (1SNA166776R0700) is an ENTRELEC ESSAILEC 20-point multicircuit test socket designed to provide an organised interface for electrical testing, measurement, monitoring and commissioning. It forms part of the ESSAILEC test block system used in secondary circuits associated with current and voltage transformers, meters and protection relays.
The M20-P-C5A uses a 20-way socket configuration with clip connection technology, allowing multiple test circuits to be grouped within a single compact assembly. ESSAILEC plug-and-socket technology supports simultaneous testing of multiple circuits and helps engineers carry out maintenance or equipment replacement without repeatedly disturbing permanent field wiring.
The ESSAILEC system incorporates make-before-break contact operation, coding between compatible plugs and sockets and protection against reverse plug insertion. This makes the M20-P-C5A particularly suitable for professional protection, metering and monitoring panels where reliable, repeatable and clearly organised test access is required.

Reliable Multicircuit Testing for Protection and Metering Systems
ESSAILEC test blocks are designed to simplify testing operations within secondary circuits connected to current transformers, voltage transformers, sensors, meters and protection relays. The plug-and-socket architecture allows test equipment to be introduced through a dedicated interface for measurement, monitoring, injection, servicing and equipment replacement.
The M20-P-C5A extends this concept to a 20-point multicircuit format, providing a practical way to organise numerous test connections within protection and metering panels. ESSAILEC coding, reverse-insertion protection and make-before-break contact operation help create repeatable testing procedures while reducing unnecessary manipulation of permanent installation wiring.
Typical Applications
- Current and voltage transformer secondary circuits.
- Protection relay testing and commissioning.
- Electrical energy metering systems.
- Measurement and monitoring circuits.
- Test signal and injection applications.
- Substation protection and control panels.
- Switchgear testing and maintenance.
- Industrial and utility power distribution systems.
