1sna168522r2300 – bjm8 4 poles

Why Choose the TE Connectivity BJM8-4 1SNA168522R2300 4-Pole Jumper Bar?

The TE Connectivity 1SNA168522R2300, identified as BJM8-4, is a 4-pole jumper bar designed for compatible ENTRELEC SNA terminal blocks. With four connection positions and an 8 mm pitch, it provides a compact and efficient method of electrically cross-connecting adjacent terminals that need to share a common potential.

The BJM8-4 is rated at 41 A for the main circuit and is specifically listed for use with the D4/8.D2.P.SF terminal block. Its manufacturer-matched construction eliminates the need to create multiple individual wire links, helping panel builders achieve cleaner terminal rows and more efficient assembly.

This grey jumper bar measures approximately 8 mm wide, 21.5 mm high and 8 mm deep, with a net weight of approximately 9.5 g. As part of the established TE Connectivity / ENTRELEC SNA accessory range, it is suitable for professional industrial control, automation and electrical distribution installations.

Key Advantages

• Provides 4-pole cross-connection across compatible terminal blocks.
• 8 mm spacing matches the associated SNA terminal block system.
• Rated for a main-circuit current of 41 A.
• Reduces individual jumper wiring for common-potential distribution.

Reliable 4-Pole Cross-Connection for SNA Terminal Blocks

Terminal block jumper bars provide a practical way to distribute a common electrical potential across adjacent connection points. By replacing separate wire links with a purpose-designed cross-connector, installers can reduce conductor preparation, simplify wiring and create terminal assemblies that are easier to inspect and maintain.

The TE Connectivity BJM8-4 combines four poles, 8 mm spacing and a 41 A main-circuit rating in a compact accessory designed specifically for compatible SNA terminal blocks. Its matched dimensions and electrical characteristics make it a dependable choice for professional control-panel and industrial wiring installations.

Typical Applications

• D4/8.D2.P.SF terminal block assemblies.
• Common-potential distribution across terminal rows.
• Industrial control and automation panels.
• Machine and equipment electrical systems.
• Switchgear and controlgear assemblies.
• Power distribution and control circuits.
• Industrial panel building and OEM equipment.
