Why Choose the TE Connectivity 1SNA176278R1600 BJMI5-2 IP20 Jumper Bar?

The TE Connectivity 1SNA176278R1600, product designation BJMI5-2, is a 2-pole insulated jumper bar designed for compatible TE Connectivity / ENTRELEC SNA terminal blocks. It provides a secure method of electrically bridging two consecutive terminal positions, simplifying common-potential distribution in industrial control panels, machinery and automation systems.

The BJMI5-2 has a 5 mm pitch, a main-circuit rated current of 24 A and IP20 protection. Its assembled design incorporates captive screws and spacers, providing a convenient ready-to-install bridging solution while helping maintain touch protection within compatible terminal assemblies.

Designed for SNA 5 mm terminal blocks, the 1SNA176278R1600 is compatible with terminals including MA2.5/5 and several D1/5 and D2.5/5 ADO variants. The jumper weighs approximately 3.3 g and is supplied in standard packs of 10 pieces, making it suitable for new panel construction, maintenance and expansion of existing terminal installations.

IP20-Protected Bridging for 5 mm SNA Terminals

Terminal jumper bars provide an efficient alternative to installing individual wires between adjacent terminals that need to share the same electrical potential. By using a correctly matched jumper, panel builders can reduce conductor count and installation time while maintaining a compact and organised terminal arrangement.

The BJMI5-2 combines two-pole bridging with an insulated IP20 design and captive connection hardware. Its 5 mm pitch and 24 A current rating make it a purpose-designed accessory for compatible ENTRELEC SNA terminals, including the MA2.5/5 family and selected ADO terminal blocks.

Typical Applications

• Industrial electrical control panels.
• TE Connectivity / ENTRELEC SNA terminal assemblies.
• Common-potential distribution between two consecutive terminals.
• MA2.5/5 and compatible 5 mm terminal block installations.
• Machine-building and factory automation systems.
• Switchgear, process control and panel wiring.
