£20.06
The TE Connectivity KEM-3 (1SNA166962R0000) is a dedicated TH35 rail mounting kit for compatible ENTRELEC ESSAILEC test block sockets. Designed as part of the ESSAILEC accessory range, it enables suitable base-mounted sockets to be securely installed on standard TH35 DIN rail within protection, metering, measurement and electrical testing panels.
The KEM-3 provides a purpose-designed mounting solution rather than requiring a custom panel arrangement. It is specifically identified for TH35 rail mounting and is compatible with base-mounted ESSAILEC sockets, making it useful when integrating ESSAILEC current or voltage test blocks into conventional DIN rail-based control and protection assemblies.
Each KEM-3 mounting kit weighs approximately 24 g and is supplied in a manufacturer pack of 10 pieces. As a genuine TE Connectivity accessory, it provides the correct mechanical interface for compatible ESSAILEC equipment and is suitable for both new panel construction and modifications to existing protection and metering installations.
ESSAILEC test blocks are widely used to provide dedicated test interfaces within current transformer, voltage transformer, protection relay and metering circuits. Where a compatible socket uses base mounting, the KEM-3 provides the mechanical hardware needed to integrate that socket onto a TH35 rail, allowing the test system to fit naturally alongside other DIN rail-mounted electrical equipment.
Using the correct manufacturer mounting kit helps maintain a secure and organised installation while simplifying panel design. The KEM-3 can therefore be used when constructing new ESSAILEC assemblies or adapting compatible base-mounted test sockets for TH35 rail installation during panel upgrades and maintenance.
