jb5-10 – jumper bar zk2.5/zs4 terminal

Why Choose the TE Connectivity JB5-10 Jumper Bar?

The TE Connectivity JB5-10 (1SNK905310R0000) is a 10-pole jumper bar designed to electrically bridge compatible ENTRELEC SNK terminal blocks with 5.2 mm spacing. Suitable for terminal families including compatible ZK2.5 and ZS4 terminals, it provides a compact method of distributing a common electrical potential across multiple adjacent terminal positions.

The JB5-10 uses a screwless push-in mounting system, allowing the jumper to be fitted into compatible terminal block jumper channels without individual wired links between each position. Its 10-pole configuration supports efficient potential distribution, while pre-cut poles provide flexibility when adapting the jumper to different circuit configurations.

Rated at 32 A and 1000 V IEC, the JB5-10 is suitable for demanding industrial power, control and distribution applications. Its orange polyamide insulation provides clear visual identification, while IP20 protection, a UL 94V-0 flammability rating and an operating temperature range of -55 to +110 °C support reliable use in professional electrical installations.

Reliable Potential Distribution Across Terminal Blocks

The JB5-10 allows multiple compatible terminal positions to be electrically commoned without installing individual wire links between each terminal. Its 10-pole format is particularly useful for distributing supply potentials, common signals or other shared electrical connections across a terminal row, helping simplify wiring and reduce panel assembly time.

The screwless push-in mounting and positive-locking design provide convenient installation into compatible jumper channels, while the pre-cut pole arrangement can be adapted for different circuit configurations. With ratings of 32 A, 1000 V IEC and 8000 V impulse withstand, the JB5-10 provides a compact bridging solution for professional industrial terminal assemblies.

• Common-potential distribution across terminal block rows.
• ZK2.5 and ZS4 terminal block assemblies.
• Industrial control panels and automation cabinets.
• Power and control circuit distribution.
• PLC and process control panels.
• Switchgear and electrical distribution equipment.
• Machine building and OEM electrical systems.
