Blackburn FBE4H140A1-24 XFLEX BRAID 4 9/16H 1/4 X 3 X 24 IN

It's a flat, extra-flexible braided copper connector used to carry current between two bolted terminals that move relative to each other, typically switchgear, disconnects, bus links, and transformer terminations. The conductor is tin-plated copper in a flat flexible braid, so it absorbs vibration, thermal expansion, and slight misalignment that a rigid bus bar cannot.

Four holes per pad. It is a 4-hole extra flexible braid connector, so the terminal pads are drilled for a four-bolt pattern rather than the two-bolt NEMA pattern. If the equipment pad you are landing on is drilled for two bolts, this is the wrong configuration.

24 inches. That's the overall cable length, so when you are figuring travel between two fixed terminals, plan the mounting centers so the braid sits with slack rather than pulled straight, otherwise it can't flex and the bolt holes take the load.

The FBE4H140A1-24 is built to CEI 60694 and IEEE/ANSI C37.34-1994, the switchgear connector standards a utility or industrial spec writer will typically call out for high-voltage air switch and bus connections.

Yes, country of origin on the FBE4H140A1-24 is the United States, which matters for federal, utility, and Buy American funded projects that require domestic origin documentation on electrical connectors.

One braid per order. The selling unit of measure is each, so if you're jumping three phases you need three, and mounting bolts, washers, and Belleville hardware are ordered separately.

Use a braid like the FBE4H140A1-24 wherever the two terminals move: expansion joints in a bus run, connections to a switch blade or operating mechanism, transformer bushings that shift thermally, and anywhere vibration would fatigue solid bar. Rigid bar is the choice for a fixed, supported run with no relative motion. The flat flexible braided construction here is specifically for the moving case.

The braid on the FBE4H140A1-24 is tin-plated copper. The tin plating slows oxidation on the strands and at the bolted pad interface, which keeps contact resistance stable outdoors and in damp or corrosive switchyard environments. Bare copper works electrically but oxidizes at the joint faster.
