Why Choose the TE Connectivity FIM20-6.6 ESSAILEC Multicircuit Plug?

The TE Connectivity FIM20-6.6 1SNA166909R0600 is a dedicated 20-position multicircuit plug from the ENTRELEC ESSAILEC test and measurement range. Designed as a removable interface for compatible ESSAILEC test sockets, it allows engineers to connect test, measurement and maintenance equipment to multiple secondary electrical circuits through a single organised plug assembly.

The FIM20-6.6 incorporates 6.6 coding, helping ensure correct mating with the corresponding coded ESSAILEC socket and reducing the possibility of connecting test equipment to an unintended circuit. The plug is also supplied with a protective cover, supporting protection of the contact interface when incorporated into the appropriate test arrangement.

ESSAILEC multicircuit technology is particularly suited to applications involving current and voltage transformer secondary circuits, metering equipment and protection relays. By providing a defined removable connection point, the FIM20-6.6 supports measurement, monitoring, commissioning and maintenance procedures without repeatedly altering the permanent wiring inside the electrical panel.

Reliable Multicircuit Access for Electrical Testing

The ESSAILEC system uses permanently installed sockets and removable plugs to provide controlled access to electrical measurement and protection circuits. This arrangement allows technicians to connect appropriate test equipment during commissioning, routine inspection or maintenance while reducing the need to disconnect individual conductors from the fixed installation.

With its 20-position configuration and 6.6 coding, the FIM20-6.6 is suited to applications where numerous circuit connections need to be grouped into a single removable interface. Coding provides additional differentiation between compatible test arrangements, supporting organised and repeatable working practices in complex switchgear and protection panels.

Typical Applications

• Current and voltage transformer secondary circuits.
• Electrical metering and measurement panels.
• Protection relay testing and commissioning.
• Substation control and protection systems.
• Industrial switchgear assemblies.
• Power monitoring installations.
• Meter and protection-relay maintenance.
• Multicircuit electrical test and measurement systems.
