The TE Connectivity 1SNA167934R1700, designated COR-C-5 and manufacturer-referenced as COR-C-R5-6.6, is a pre-wired current test plug designed for compatible ESSAILEC test block systems. It provides a ready-assembled connection interface for current-transformer secondary circuits used in electrical protection, metering, monitoring and commissioning applications.
The COR-C-5 features a 2 × 4-pole green plug with four internally short-circuited pins numbered 1-2-3-4. This configuration is specifically suited to current-circuit testing, where maintaining a controlled current-transformer secondary path is important during test and maintenance procedures.
The assembly is supplied with four 4 mm black test plugs, 2.5 mm² conductors and approximately 2 m of cable. With a rated current of 15 A, the COR-C-5 provides a practical factory-assembled test solution for professional power distribution, protection relay and metering installations.
ESSAILEC test systems are designed to provide controlled access to current-transformer secondary circuits for measurement, protection-relay testing and maintenance. Dedicated current test plugs help technicians establish the required test connections while reducing the need to disturb permanent field wiring.
The COR-C-5 combines a pre-wired 2 × 4-pole plug, four internally short-circuited contacts, 2.5 mm² conductors and four 4 mm test plugs in a factory-assembled solution. This configuration makes it particularly suitable for repeatable testing and commissioning procedures in electrical protection and metering installations.
