Why Choose the TE Connectivity 1SNA166643R0200 COR-C-3 Prewired Current Test Plug?
The TE Connectivity 1SNA166643R0200 is a specialised prewired current test plug designed for current measurement, protection relay testing and maintenance of electrical secondary circuits. Also identified as the COR-C-3, this component forms part of the established ENTRELEC ESSAILEC measuring and testing system and provides a ready-wired interface for connecting test equipment to compatible current test sockets.
The COR-C-3 incorporates a red 2-pole plug with two contact pins connected to two yellow bayonet safety test plugs. Supplied as a prewired assembly, it helps reduce test preparation and provides technicians with a convenient, repeatable connection arrangement for commissioning, measurement and maintenance procedures.
Designed for ESSAILEC current circuits, the 1SNA166643R0200 uses 2.5 mm² conductors with a 2 m cable length. The associated ESSAILEC current test system is rated at 400 V and 15 A, with a 4 kV impulse withstand voltage, making the COR-C-3 suitable for demanding protection, metering, switchgear and utility applications.
