TE Connectivity 1SNK916304R0000 JB16-4 is a 4-pole 16 mm pitch orange screw-mounted jumper bar rated at 125 A and 1000 V IEC for electrically bridging compatible ENTRELEC SNK Series terminal blocks.

The TE Connectivity 1SNK916304R0000, also identified as JB16-4, is a robust 4-pole jumper bar designed for electrically bridging compatible terminal blocks. Part of the TE Connectivity ENTRELEC SNK Series, it provides a reliable method of distributing a common electrical potential across adjacent terminals in industrial control panels, power distribution systems and machinery.
The JB16-4 features a screw-mounted retention system for secure installation into compatible terminal blocks. Its 4-pole configuration and 16 mm pitch allow four adjacent compatible terminal positions to be electrically connected, helping simplify panel wiring, reduce the need for individual bridging conductors and maintain an organised electrical installation.
With an IEC current rating of 125 A and an IEC voltage rating of 1000 V, the 1SNK916304R0000 is designed for demanding industrial electrical applications. It also provides a 4200 A short-time withstand current rating for 1 s and operates across a wide -55–110 °C temperature range, making it suitable for high-current terminal block installations.
Jumper bars provide an efficient method of electrically connecting adjacent terminal blocks that need to share a common electrical potential. Using a purpose-designed jumper bar instead of individual bridging wires can reduce installation time, simplify panel wiring and provide a compact, consistent electrical connection across multiple terminal positions.
The ENTRELEC SNK Series is designed for professional industrial connection applications, and the JB16-4 provides a high-current bridging solution for compatible 16 mm pitch terminal blocks. Its screw-mounted design, 125 A IEC current rating and high short-time withstand capability make it particularly suitable for demanding power distribution and industrial control applications.
