The TE Connectivity 1SNA166778R1100, also identified as COR-C-2, is a specialised ESSAILEC 2x4-pole prewired current plug for injection testing designed for current transformer measurement, protection and test applications. Part of the established TE Connectivity / Entrelec ESSAILEC range, it provides a purpose-built connection between current circuits and compatible electrical test equipment.
The COR-C-2 assembly incorporates a green FIC-2/4-1 2x4-pole plug with four short-circuited pins on positions 1-2-3-4. This configuration is specifically intended for current injection and testing applications, helping engineers establish the required circuit arrangement when working with compatible ESSAILEC current test blocks.
The prewired assembly includes green, grey, brown and yellow bayonet security test plugs for connection to test equipment. With an assembly weight of approximately 0.47 kg, the COR-C-2 provides a convenient ready-wired solution for commissioning, protection relay testing, current measurement and maintenance operations.
ESSAILEC prewired current plugs provide a dedicated interface between current transformer circuits and electrical test equipment. The COR-C-2 is specifically configured for injection testing, with four short-circuited pins incorporated into its 2x4-pole plug to provide the required circuit arrangement for compatible ESSAILEC current applications.
The prewired design reduces the need to assemble individual test leads during commissioning and maintenance. Its colour-coded bayonet security test plugs provide convenient identification when connecting suitable test equipment, making the COR-C-2 well suited to protection relay testing, current injection, switchgear commissioning and substation maintenance.
