Blackburn EXH150A1287 FLEX, CON. 4 HOLES 1500AMP 287MM

It's a flexible braid shunt connector for carrying current between two bolted terminals that need to move relative to each other, such as switchgear blades, disconnects, bus expansion joints, and grounding switch connections. The braid is extra flexible tin-plated copper in a flat shape, with a four-hole pad at each end for bolted termination, rated 1500 amps.

287 mm, or 11.30 inches, measured as the cable length. That length is the span the braid covers between the two bolted pads, so measure the terminal-to-terminal distance on your switchgear plus the slack you need for movement before ordering.

The EXH150A1287 is built to IEEE/ANSI C37.34, the standard covering high-voltage air switches and their current-carrying connections. That is the reference a utility or substation spec engineer will be looking for on a shunt of this class.

The braid on the EXH150A1287 is tin-plated copper. Tin plating slows oxidation on the strands and on the bolted pad faces, which keeps contact resistance stable at outdoor and substation terminations, and it mates with aluminum or tin-plated bus without the galvanic issues bare copper brings.

No hardware is included. The EXH150A1287 is sold each, as the braid with a four-hole pad at each end, so you supply the bolts, nuts, and washers sized to your bus drilling and torque spec.

At 1500 amps the four-hole pad is what you want. Four bolts spread the clamping force over a wider pad face, which holds contact pressure and keeps joint resistance and heating down at high continuous current. Two-hole pads are used on smaller shunts at lower ampacity. The EXH150A1287 is the four-hole, 1500 amp version.

EXH150A1287. The designation breaks down to the flexible braid connector family, 1500 amp rating, and the 287 mm length, and it is ordered as a single piece.

Yes, country of origin is the United States. That matters if you are procuring against a domestic-content requirement on a utility or public-works project.
