JB8-10 – 10 WAY JUMPER BAR (FOR ZS10/ZS16)

Why Choose the TE Connectivity JB8-10 10-Way Jumper Bar?

The TE Connectivity JB8-10 (1SNK908310R0000) is a 10-pole jumper bar designed for electrical cross-connection and potential distribution across compatible ENTRELEC SNK terminal blocks. With an 8 mm pitch, it is suitable for compatible terminal assemblies including ZS10 and selected related SNK terminals, providing an efficient alternative to individual wired bridging connections.

The JB8-10 features screwless mounting and positive locking, allowing it to be inserted directly into compatible terminal block jumper channels. Its pre-cut poles support standard and alternate jumpering arrangements, giving panel builders flexibility when creating common-potential groups within control, power and distribution circuits.

Rated at 57 A and 1000 V IEC, the JB8-10 also provides a short-time withstand current of 1200 A for 1 s and an IEC impulse withstand voltage of 6000 V. Its orange polyamide insulation, IP20 protection and wide -55 to +110 °C operating temperature range make it a robust conducting accessory for industrial terminal block installations.

Key Advantages

• 10-pole configuration distributes a common electrical potential across multiple compatible terminals.
• 8 mm pitch is designed for compatible ENTRELEC SNK terminal block assemblies.

Reliable Potential Distribution for 8 mm Terminal Assemblies

The JB8-10 provides an efficient way to electrically common multiple terminal positions without installing separate wire links. Its 10-pole construction allows a shared supply, common potential or control connection to be distributed across a terminal row, helping reduce wiring time and maintain a clean, organised panel layout.

Screwless mounting and positive locking simplify assembly, while the pre-cut pole design allows the jumper configuration to be adapted to the required circuit arrangement. With ratings of 57 A and 1000 V IEC, plus 1200 A short-time withstand capability, the JB8-10 is well suited to professional industrial power, control and automation wiring.

Typical Applications

• Common-potential distribution across terminal block rows.
• Compatible ZS10 and 8 mm spacing SNK terminal assemblies.
• Industrial control panels and automation cabinets.
• Power and control circuit distribution.
• PLC and process control systems.
• Switchgear and electrical distribution equipment.
• Machine building and OEM electrical installations.
