Why Choose the TE Connectivity BJS551-2 1SNA205778R2100 2-Pole Jumper Bar?
The TE Connectivity BJS551-2 1SNA205778R2100 is a heavy-duty 2-pole jumper bar designed to electrically bridge adjacent compatible ENTRELEC power terminal blocks. As part of the established TE Connectivity ENTRELEC SNA terminal block accessory range, it provides a purpose-designed solution for creating reliable common electrical connections in industrial control panels, power distribution assemblies and machinery.
This jumper bar enables two adjacent terminal blocks to be interconnected without installing a separate bridging conductor. Its robust construction and dedicated terminal compatibility help simplify panel assembly, reduce wiring requirements and provide a secure electrical bridge between connected poles.
With a 2-pole configuration and 55 mm pole spacing, the BJS551-2 is designed for use with compatible D185/55.FF and D300/55.FF power terminal blocks, including corresponding Ex variants. The 1SNA205778R2100 is therefore well suited to high-capacity industrial terminal assemblies where dependable power distribution and organised panel wiring are required.

Reliable Power Terminal Bridging for Industrial Panels
Jumper bars provide an efficient means of creating a common electrical connection between adjacent terminal blocks. Instead of installing and terminating a separate conductor between terminals, a purpose-designed jumper establishes the connection directly, helping reduce wiring time and maintain an organised power distribution assembly.
The BJS551-2 is specifically matched to compatible TE Connectivity ENTRELEC power terminal blocks with 55 mm spacing. Its dedicated 2-pole design makes it particularly useful for linking adjacent D185/55.FF and D300/55.FF terminals in industrial electrical panels, machinery and power distribution installations.
Typical Applications
- Industrial power distribution panels.
- Heavy-duty terminal block assemblies.
- Machinery and equipment power connections.
- Electrical control cabinets.
- Factory automation and production equipment.
- OEM machine building and panel assembly.
