TE Connectivity COP-E-2 1SNA167012R1600 is an ENTRELEC ESSAILEC coding accessory designed to support controlled plug-and-socket identification in compatible protection, metering and electrical test block systems.
£1.47
The TE Connectivity COP-E-2 1SNA167012R1600 is a dedicated ESSAILEC coding accessory for the ENTRELEC measuring and testing system. It is used within compatible ESSAILEC test block assemblies to support the system's mechanical coding arrangement, helping ensure that test plugs are connected only to the intended socket configuration.
Correct coding is particularly important in protection, metering and measurement installations where several current, voltage or other secondary circuits may be positioned close together. ESSAILEC incorporates coding between plugs and sockets to help prevent connection errors between different circuits and to protect against incorrect plug insertion.
The COP-E-2 is a compact system accessory rather than a standalone electrical switching device. Manufacturer part number 1SNA167012R1600 is identified as model COP-E-2 within the ESSAILEC product family and carries EAN 3472591670127, making it straightforward to specify as a replacement or additional coding component for compatible installations.
ESSAILEC test blocks are designed for current and voltage measurement, monitoring, injection, repair and replacement operations involving meters and protection relays in transformer and sensor secondary circuits. The system combines dedicated plugs and sockets with mechanical coding to make repetitive test procedures quicker and more controlled.
Coding accessories such as the COP-E-2 contribute to this safety concept by differentiating compatible connection arrangements. This is especially useful in switchgear and protection panels containing several test circuits, where connecting a test plug to the wrong circuit could lead to incorrect measurements or disruption of the intended testing procedure.
