1sna167623r2700 – ir2 connector

Why Choose the TE Connectivity 1SNA167623R2700 IR2 Connector?

The TE Connectivity 1SNA167623R2700 is an IR2 H-shaped test pin adaptor and short-circuit bridge designed for use with compatible ESSAILEC® test block systems. Part of the TE Connectivity ENTRELEC test and measurement accessory range, the IR2 provides a practical means of bridging compatible test connections during commissioning, measurement, protection testing and maintenance procedures.

ESSAILEC® test blocks are engineered for electrical protection, metering and instrument-transformer circuits where technicians require convenient access for testing while maintaining an organised connection system. The IR2 adaptor complements this system with its H-shaped configuration, allowing it to function as a short-circuit bridge in suitable ESSAILEC® test arrangements.

The 1SNA167623R2700 has compact dimensions of approximately 30 mm high × 3 mm wide × 54 mm deep and a net weight of approximately 35 g. It is supplied in a pack quantity of 5 and is suitable for professional electrical testing applications in switchgear, substations, protection panels and industrial power systems.

Reliable Short-Circuit Bridging for ESSAILEC® Test Systems

Electrical test blocks provide engineers with controlled access to secondary current and voltage circuits during commissioning, measurement and maintenance work. In protection and metering installations, dedicated test accessories allow temporary circuit configurations to be created without unnecessarily disturbing permanent field wiring.

The TE Connectivity IR2 is specifically designed as an H-shaped short-circuit bridge adaptor within the ESSAILEC® accessory system. Used with compatible test-block arrangements, it provides a convenient solution for bridging test connections and supports efficient procedures in electrical protection, metering and power-distribution environments.

Typical Applications

• ESSAILEC® electrical test block systems.
• Current transformer secondary circuits.
• Voltage and measurement test circuits.
• Protection relay testing and commissioning.
• Electrical metering panels.
• Substation protection and control systems.
• Industrial switchgear assemblies.
• Power distribution and control panels.
• Electrical maintenance and diagnostic testing.
