Why Choose the TE Connectivity BJMI12-3 3-Pole IP20 Jumper Bar 1SNA179628R1000?
The TE Connectivity 1SNA179628R1000, identified as BJMI12-3, is a 3-pole screw-in cross-connection jumper bar from the ENTRELEC SNA terminal block accessory range. Designed for compatible C16/12 and M16/12 screw-clamp terminal blocks, it provides an efficient way to electrically bridge three terminal positions and distribute a common potential within industrial control and power distribution systems.
The BJMI12-3 features an IP20 insulated design with captive screws and spacers, providing protection against accidental contact while simplifying installation. Its configurable construction allows consecutive terminals to be linked and also permits unwanted screws and spacers to be removed when selected, non-consecutive terminal positions need to be interconnected.
With a 12 mm pitch, 76 A rated main-circuit current and a net weight of approximately 9 g, the 1SNA179628R1000 provides a compact, high-current cross-connection solution for professional panel construction. It is the current BJMI12-3 reference replacing the earlier 1SNA176681R2300 part number.

Flexible High-Current Potential Distribution for SNA Terminal Blocks
Cross-connection jumper bars provide a convenient way to distribute a common electrical potential between multiple terminal blocks without installing separate conductors between each position. The BJMI12-3 links three compatible SNA terminals through a compact screw-mounted assembly, helping reduce wiring complexity and installation time while maintaining an organised terminal strip.
The captive screw and spacer arrangement also provides additional installation flexibility. Individual screws and spacers can be removed where a terminal position does not need to be interconnected, allowing the jumper to accommodate selected connections within the assembly while retaining its 76 A rated-current capability and 12 mm terminal spacing.
Typical Applications
- C16/12 and M16/12 SNA terminal block assemblies.
- Industrial electrical control panels.
- Common-potential and power distribution circuits.
- PLC and industrial automation cabinets.
- Machine control and manufacturing equipment.
- OEM panel building and electrical system integration.
