Blackburn FBS4H150A1-18 – Frequently Asked Questions
1) What is the Blackburn FBS4H150A1-18 flexible braid connector used for?
It's a flat, flexible tin-plated copper braid shunt used to carry current between two bolted terminations that need to move, flex, or absorb vibration and thermal expansion - typical of switchgear, disconnect switches, transformer terminals, and bus bar jumpers. The braid is 18 inches long with a 4-hole bolt pattern at each end.
2) What standards does the Blackburn FBS4H150A1-18 flex braid meet?
The braid is built to CEI 60694 and IEEE/ANSI C37.34-1994, the switchgear standards for high-voltage enclosed air switches. If your spec calls out C37.34 for switch connectors, this one answers it. It is also made in the United States, which matters on Buy American and domestic-preference jobs.
3) Why tin-plated copper instead of bare copper braid?
The conductor is tin-plated copper. The tin plating slows oxidation at the bolted pads, which is what keeps contact resistance from creeping up over time in outdoor or humid switchgear enclosures, and it makes the braid compatible with aluminum bus without the galvanic issues of bare copper against aluminum.
4) Does the Blackburn FBS4H150A1-18 come with the bolts and hardware to mount it?
No. It's sold as a single braid, each, with the drilled pads only. Bolts, nuts, flat and Belleville washers are ordered separately and need to suit the bus or terminal pad you're landing on.
5) Can I cut a flex braid connector shorter to fit my span?
Don't. The FBS4H150A1-18 is a finished assembly, 18 inches overall, with the braid bonded into drilled pads at both ends. Cutting it destroys one termination. Pick the braid length that matches the span you need, and leave a little slack so the braid flexes rather than pulling on the terminations.
6) What's the difference between a flexible braid shunt and a rigid bus link?
A rigid link is fine where both terminations are fixed and aligned. Use a flexible flat braid like the FBS4H150A1-18 where the joint has to move: a switch blade that rotates, equipment on vibration isolators, or a long bus run that grows and shrinks with temperature. The braid takes that movement instead of transmitting it into the bolted pads.
7) How do I identify the right Blackburn flex braid when reordering?
Order by the manufacturer part number, FBS4H150A1-18. That call-out covers the 4-hole pattern and the 18 inch length in one number, so quoting it avoids the mix-ups that come from describing hole count and length separately.
