Blackburn FBE2H040A1-12 XFLEX BRAID 2 9/16H 3/16X1.5X12 IN

It is an extra flexible braid connector with two bolt holes per pad, made from tin-plated copper braid in a flat conductor form. Flexible braid connectors like this bridge between rigid bus bar, switchgear terminals, or grounding points where the connection has to tolerate movement, thermal expansion, or vibration that a solid bar cannot absorb. The braid is 12 inches long and sold each.

Two holes per pad, which is what the 2H in the catalog description and the 2-hole product type refer to. The described pad geometry is 9/16 hole with braid dimensions of 3/16 x 1.5 x 12 inches. Match the two-hole pad against a two-hole NEMA pad on your bus or switch terminal; a single-hole terminal will not take it without an adapter pad.

The braid measures 12 inches overall. Because a flexible braid needs slack to do its job, the usable center-to-center distance between your two bolted pads is shorter than 12 inches once you allow the loop or bend that absorbs movement. Measure your pad-to-pad gap and leave room for that bend rather than pulling the braid taut, which defeats the point of using flexible braid at all.

The FBE2H040A1-12 is built to CEI 60694 and IEEE/ANSI C37.34-1994. C37.34 is the test code for high-voltage air switches, which is why this braid shows up on switch and disconnect connections in substation and switchgear work. Those are the two standards stated for the part.

The conductor is tin-plated copper. Tin plating slows the oxidation that bare copper suffers in damp or corrosive air, so the contact resistance at the bolted pad stays more stable over time and the braid takes less cleaning at each maintenance interval. For outdoor switchgear and substation grounding, that is the reason to pick a plated braid over bare.

Use braid where the two ends move relative to each other. Anywhere a disconnect switch blade rotates, a transformer bushing shifts with thermal cycling, or equipment vibrates, a rigid bar transmits that stress into the terminal and eventually cracks a pad or loosens bolts. The FBE2H040A1-12 is a flexible flat braid built for that duty, tested to IEEE/ANSI C37.34-1994 for high-voltage air switch service. If both ends are rigidly fixed and stationary, solid bar is the simpler choice.

The FBE2H040A1-12 is sold as the braid connector alone, each. Bolts, nuts, Belleville washers, and any flat washers or joint compound for the bolted pads are ordered separately and should be sized to the 9/16 holes in the pads.

Country of origin is the United States. That matters on federally funded utility and public works jobs where domestic sourcing is a condition of the contract, so keep the MPN FBE2H040A1-12 on your submittal.
