£45.47
The TE Connectivity 1SNA167624R2000 is an IR3 adaptor for ESSAILEC® electrical test systems, specifically designed to provide an interface between an FCB bayonet test plug and a ring-tongue test interface. Part of the TE Connectivity ENTRELEC ESSAILEC® accessory range, it provides a practical connection solution for current-transformer, protection and metering test circuits.
ESSAILEC® test blocks are designed to provide convenient and controlled access to secondary electrical circuits during commissioning, measurement, maintenance and protection-relay testing. The IR3 expands the versatility of these systems by allowing an FCB bayonet test connection to interface with equipment using a ring-tongue connection arrangement.
The 1SNA167624R2000 IR3 has a manufacturer-listed unit weight of approximately 6.4 g and is supplied in a pack quantity of 10. Its dedicated ESSAILEC® design makes it suitable for professional electrical testing applications in substations, switchgear, metering panels and industrial power-distribution systems.
ESSAILEC® test blocks provide dedicated connection points for accessing current and voltage circuits associated with instrument transformers, meters and protection equipment. Using dedicated test accessories allows engineers to establish the required test configuration while minimising disturbance to permanent panel wiring.
The TE Connectivity IR3 provides a specialised transition between an FCB bayonet test plug and a ring-tongue test interface. This makes it a useful accessory when test equipment or associated circuitry requires these different connection formats, supporting efficient commissioning, diagnostic and maintenance procedures.
