BJMI12-3P Entrelec 3 Pole Jumper Bar, 12mm, for SNA Terminals 1SNA179628R1000

The BJMI12-3P (order code BJMI12-3, alternate code 1SNA179628R1000) is a 3 pole jumper bar manufactured by TE Connectivity (Entrelec) with a 12mm spacing, designed for use with SNA screw clamp terminal blocks.

This IP20-rated perforated jumper bar provides a reliable method of linking multiple terminal blocks within an electrical panel, simplifying circuit wiring and reducing installation time. Its captive screw and spacer design allows connection of both consecutive and non-consecutive blocks, giving installers maximum flexibility on the panel rail.

Key Features

• 3 Pole Configuration: Links three SNA terminal blocks in a single assembly, reducing wiring complexity across multiple circuits.
• 12mm Terminal Spacing: Precisely matched to M16/12 and C16/12 SNA blocks, ensuring a secure and correctly pitched fit.
• Captive Screws and Spacers: Pre-assembled design speeds up installation and prevents loss of small components during panel build.
• Selective Connection: Unnecessary screws and spacers can be removed to allow connection of non-consecutive blocks, offering flexible circuit configuration.
• Rated to 76A: Suitable for main circuit applications requiring a high current-rated jumper solution.
• IP20 Protection: Meets IP20 degree of protection in accordance with IEC 60529 and IEC 60947-1, ensuring safe use in control panel environments.
• Multi-Rail Compatible: Mounts on G32, TH35-7.5, and TH35-15 DIN rails, covering the most common rail types found in industrial enclosures.

Applications

The BJMI12-3P jumper bar is used in industrial control panels, switchgear assemblies, and power distribution enclosures where multiple terminal blocks need to share a common potential. It is particularly suited to machine building, process automation, and panel wiring applications where M16/12 or C16/12 SNA screw clamp terminals are installed on standard DIN rail. The ability to skip poles makes it equally useful in mixed-circuit layouts where only selected terminals require interconnection.

Standards and Compliance

The BJMI12-3P carries CE certification, is RoHS compliant, and meets IP20 protection in accordance with IEC 60529 and IEC 60947-1, with a Declaration of Conformity reference 1SND225001C1009.
