TE Connectivity KEM-1 1SNA166928R2000 is an ENTRELEC ESSAILEC flush mounting kit designed for compatible ring-tongue connection type test sockets used in protection, metering and instrumentation systems.
Why Choose the TE Connectivity KEM-1 ESSAILEC Flush Mounting Kit?
The TE Connectivity KEM-1 1SNA166928R2000 is a dedicated ESSAILEC flush mounting kit designed for compatible test sockets with ring-tongue connections. Part of the TE Connectivity / ENTRELEC ESSAILEC measuring and testing system, it provides the mounting hardware required to install suitable ESSAILEC sockets through a panel for a secure and organised test interface.
The KEM-1 is specifically intended for ring-tongue connection type sockets (VA) and is used when a flush-mounted installation is required. ESSAILEC installation guidance specifies that the flush mounting kit is fitted to the socket before the socket is installed into the panel, helping create a reliable mechanical installation for protection, metering and instrumentation applications.
With compact dimensions of approximately 50 mm wide × 43 mm high × 74 mm deep and a net weight of approximately 18 g, the KEM-1 provides a lightweight mounting solution for ESSAILEC installations. It is used across compatible ESSAILEC current, voltage, polarity and trip socket ranges that employ ring-tongue termination.

Reliable Flush Mounting for ESSAILEC Test Sockets
ESSAILEC measuring and testing blocks provide dedicated interfaces for current and voltage measurement, monitoring, injection, commissioning and maintenance of meters and protection relays. Where the test socket must be presented through the front of an electrical panel, a suitable mounting arrangement is required to position and retain the socket correctly.
The KEM-1 fulfils this role for compatible ring-tongue ESSAILEC sockets. The kit is mounted onto the socket before panel installation, providing a purpose-designed solution for integrating the test interface into protection panels, switchgear, substations and industrial metering assemblies.
Typical Applications
Flush mounting of compatible ESSAILEC test sockets.
Current transformer test block installations.
Voltage transformer test block installations.
Protection relay panels.
Electrical metering and measurement systems.
Substation protection and control panels.
Switchgear and industrial instrumentation assemblies.
