Reliable Terminal Block Commoning for Industrial Panels
Jumper bars provide an efficient method of creating a common electrical potential across multiple terminal blocks. Instead of individually wiring neighbouring terminals together, a purpose-designed jumper can distribute the connection across several poles, reducing wiring requirements while helping create cleaner and more organised control panel assemblies.
The TE Connectivity ENTRELEC BJMI12 range is designed specifically for compatible SNA terminal blocks. The 1SNA179629R1100 provides four-pole commoning at 12 mm spacing, with captive screws and spacers supporting straightforward installation and dependable mechanical connection in industrial environments.
Typical Applications
- Industrial electrical control panels.
- Terminal block commoning and cross connections.
- Power and control circuit distribution.
- Machine control and automation systems.
- Switchgear and electrical distribution assemblies.
- OEM machinery and panel building.
