jb6-10 – jumper bar zk4 terminal

Why Choose the TE Connectivity JB6-10 Jumper Bar?

The TE Connectivity JB6-10 (1SNK906310R0000) is an orange 10-pole jumper bar designed for electrically bridging compatible ENTRELEC SNK Series terminal blocks with 6 mm spacing. Its push-in, screwless design provides an efficient method of distributing a common electrical potential across multiple adjacent terminals in industrial control panels and automation equipment.

Designed for compatible SNK ZK and ZS Series terminals, including suitable ZK4 configurations, the JB6-10 provides ten bridging positions within one compact accessory. Pre-cut poles can be removed where required to create alternative bridging arrangements, providing flexibility when neighbouring terminals must be selectively interconnected.

The JB6-10 is rated at 41 A and 1000 V IEC, with an 8000 V impulse withstand voltage and 720 A short-time withstand current for 1 s. Its orange polyamide insulation, screwless retention and wide -55 to 110 °C operating temperature range make it a robust solution for professional industrial terminal assemblies.

Efficient Potential Distribution Across Terminal Blocks

Jumper bars provide a compact method of distributing a common potential across several terminal blocks without installing individual jumper wires between every connection point. This can reduce wiring time, minimise conductor clutter and help create an organised terminal assembly that is easier to inspect and maintain.

The JB6-10 provides 10 bridging positions at 6 mm spacing and uses a screwless installation method for fast integration into compatible SNK terminal assemblies. Its pre-cut pole design also enables individual positions to be removed where alternate or selective bridging is required.

Typical Applications

• Industrial electrical control panels.
• Common-potential distribution across terminal blocks.
• ZK4 and other compatible SNK terminal assemblies.
• Machine building and factory automation.
• PLC control and signal distribution circuits.
• Switchgear and electrical distribution equipment.
