Why Choose the TE Connectivity 1SNA205021R2600 BJA5-10 Jumper Bar?
The TE Connectivity 1SNA205021R2600, commonly identified as BJA5 or BJA5-10, is a 10-pole screw jumper bar designed to electrically cross-connect compatible ENTRELEC terminal blocks. Part of the established TE Connectivity ENTRELEC SNA accessory range, it provides an efficient way to distribute a common electrical potential across multiple terminals within industrial control and automation panels.
Designed for terminal blocks with 5 mm spacing, the BJA5-10 supports a rated main-circuit current of 24 A. The jumper can connect consecutive terminals or be adapted for non-consecutive connections by manually removing unnecessary jumper elements where a connection is not required, providing flexibility when configuring control circuits.
The 1SNA205021R2600 is suitable for compatible D1/5.D2.ADO, D2.5/5.D2.ADO and MA2.5/5 terminal blocks. The complete jumper assembly includes a protective cover that snaps onto the top of the terminal block, while captive screws on the jumper elements help simplify installation and reduce the risk of loose hardware during panel assembly.
Key Advantages
- 10-pole jumper bar enables efficient common-potential distribution across multiple terminals.
- Rated for a main-circuit current of 24 A.
- Designed specifically for compatible terminal blocks with 5 mm spacing.
- Unnecessary jumper elements can be manually removed for non-consecutive connections.
- Two jumper bars can be used to create alternating cross-connections.
- Supplied as a jumper assembly with a snap-on protective cover for compatible terminals.
Key Features
- TE Connectivity / ENTRELEC BJA5-10 jumper bar.
- Manufacturer part number 1SNA205021R2600.
- 10-pole screw jumper configuration.
- 24 A rated main-circuit current.
- 5 mm terminal spacing.
- Supports consecutive and selected non-consecutive terminal bridging.
- Captive screw fitted to each jumper element.
- Suitable for D1/5.D2.ADO, D2.5/5.D2.ADO and MA2.5/5 terminal blocks.
- Approximate product weight of 12 g.
- Supplied in manufacturer packs of 10 pieces.
Flexible Cross-Connection for Terminal Block Assemblies
Terminal block jumper bars allow a common electrical potential to be distributed between multiple terminals without installing individual external wires between each connection point. The BJA5-10 provides ten jumper positions for compatible 5 mm terminal blocks, helping reduce wiring time and create an organised cross-connection within control panels and automation systems.
The BJA5-10 can bridge consecutive terminals, while individual unnecessary elements may be manually detached where a connection is not required. This enables selected non-consecutive terminals to share the same potential. Two jumper bars may also be used where alternating terminal connections are required, making the accessory suitable for more complex distribution arrangements.
Typical Applications
- Common-potential distribution across DIN rail terminal blocks.
- Industrial control panel wiring and automation systems.
- PLC input and output terminal assemblies.
- Machine-building electrical cabinets.
- Instrumentation and process control wiring.
- Modification and expansion of compatible ENTRELEC terminal installations.
