1sna174394r2100 – bjs12,5 3 poles

Why Choose the TE Connectivity BJS12.5-3 1SNA174394R2100 3-Pole Jumper Bar?

The TE Connectivity BJS12.5-3 1SNA174394R2100 is a 3-pole terminal block jumper bar designed for cross-connecting compatible Entrelec SNA terminal blocks. It provides a dedicated method of electrically linking three terminal positions, allowing a common potential to be distributed efficiently within industrial control panels, machinery and electrical distribution systems.

Designed with 12.5 mm spacing, the BJS12.5-3 is specifically suitable for the Entrelec M6/12.FF terminal block. The jumper bar is supplied as a perforated bar without captive screws or spacers, with the appropriate fastening kits used to secure it to the compatible terminal blocks.

The BJS12.5-3 carries a rated main-circuit current of 41 A and weighs approximately 2.7 g per piece. Its purpose-designed construction helps reduce separate wire links between terminal positions while creating a compact, organised and maintainable terminal assembly.

Efficient Three-Pole Common-Potential Distribution

Jumper bars provide a practical way to distribute a common electrical potential across multiple terminal positions without installing individual conductors between each connection. This can reduce wiring time and conductor congestion while producing a cleaner terminal strip for inspection, troubleshooting and maintenance.

The BJS12.5-3 is specifically configured for three-position bridging on compatible M6/12.FF terminal blocks. Its 12.5 mm spacing and 41 A current rating make it a dedicated accessory for professional Entrelec terminal installations where a reliable three-pole cross-connection is required.

Typical Applications

• Industrial electrical control panels.
• M6/12.FF terminal block assemblies.
• Common-potential distribution circuits.
• PLC and industrial automation cabinets.
• Machine-building electrical systems.
• Power, control and distribution wiring.
