Why Choose the TE Connectivity FIM30-10-3 ESSAILEC Connector?

The TE Connectivity FIM30-10-3 1SNA166843R2300 is a specialist ENTRELEC ESSAILEC connector and test-block accessory designed for use within secondary electrical measurement and protection circuits. It forms part of TE Connectivity's established ESSAILEC system, which provides plug-and-play access for testing current and voltage transformer circuits without unnecessarily disturbing permanent installation wiring.

The FIM30-10-3 is intended for professional ESSAILEC installations where a dependable removable connection is required for measurement, monitoring, signal injection, commissioning or maintenance. ESSAILEC plugs and sockets combine to provide controlled access to secondary circuits associated with meters, monitoring equipment and protection relays.

Designed as part of a modular test system, the FIM30-10-3 supports structured electrical testing in switchgear, substations and industrial control equipment. ESSAILEC technology incorporates circuit coding and protection against incorrect plug insertion within compatible assemblies, helping engineers perform repeatable test procedures while maintaining clear separation between different measurement circuits.
