TE Connectivity / ENTRELEC COP-FI-1 1SNA167378R1100 is an ESSAILEC plug coding pin designed to provide mechanical coding between compatible measuring and testing block plugs and sockets.
Why Choose the TE Connectivity COP-FI-1 1SNA167378R1100 ESSAILEC Plug Coding Pin?
The TE Connectivity / ENTRELEC COP-FI-1 1SNA167378R1100 is a dedicated plug coding pin for the ESSAILEC measuring and testing block system. It is used to establish the mechanical coding of compatible ESSAILEC plugs, helping ensure that a plug is connected only to a socket with the corresponding coding arrangement.
Correct coding is particularly valuable in protection, metering and test installations containing multiple ESSAILEC circuits. By configuring the plug with the COP-FI-1 coding pin, installers can differentiate compatible connection positions and reduce the risk of inserting a test plug into an incorrectly coded socket.
The COP-FI-1 works with the corresponding COP-E-1 socket coding pin used on the ESSAILEC socket side. Coding positions within the system are identified by numbered positions including 2, 4, 6, 8, 10 and 12, enabling matching plug-and-socket coding arrangements for different test circuits.
Key Advantages

Reliable Mechanical Coding for ESSAILEC Test Connections
ESSAILEC coding provides a straightforward mechanical method of distinguishing between test circuits. The COP-FI-1 is positioned in the appropriate location within a compatible plug, while the corresponding socket uses COP-E-1 coding pins. When the coding arrangements correspond, the plug can be correctly connected to its intended socket.
This coding method is especially useful in switchgear, protection and metering panels containing several similar test connections. Correctly coded plugs and sockets help technicians identify compatible interfaces during commissioning, measurement and maintenance procedures while reducing the possibility of connection errors.
Typical Applications
ESSAILEC measuring and testing blocks.
Current transformer test circuits.
Voltage transformer test circuits.
Protection relay testing systems.
Electrical metering panels.
Switchgear and switchboard test interfaces.
Power distribution protection systems.
Industrial commissioning and maintenance installations.
