Blackburn FBE1H035A3-12 XFLEX BRAID 7/16H 3/16X1.5 X 12 IN

The FBE1H035A3-12 is a single-hole braid connector with a 7/16 inch hole at the terminal pad, so it lands on a 3/8 inch bolt or stud with normal clearance. One hole per end means you should torque it against a flat, clean pad and use a lock washer, since a single-bolt connection can rotate if it works loose.

Overall length is 12 inches, with a flat braid section measuring 3/16 by 1.5 inches in cross section. The flat, wide profile is what gives it the flex; use the 12 inch length when you need real movement between the two connection points rather than a short rigid strap.

It is built to CEI 60694 and IEEE/ANSI C37.34-1994. C37.34 is the test code for high voltage air switches, so this braid is specified for switch and disconnect shunt connections rather than as a general-purpose bonding jumper.

The conductor is tin-plated copper, which is the standard choice for outdoor switchgear and substation work because the tin plating slows oxidation on the copper braid and at the bolted interface. It is made in the United States.

Use the flexible braid where the two ends move relative to each other: switch blade travel, thermal expansion of bus, vibration, or seismic movement. A solid link there transmits stress straight into the terminal pads and eventually cracks a connection. The FBE1H035A3-12 gives 12 inches of flat, extra-flexible tin-plated copper braid to absorb that motion. Where there is no movement, a rigid bus link is the simpler connection.

Order Blackburn part FBE1H035A3-12. In that designation FBE is the extra flexible braid family, 1H is the single 7/16 inch hole terminal, and -12 is the 12 inch overall length, with a 3/16 by 1.5 inch flat braid.

Sold each. If you are jumpering both sides of a switch or ordering spares for a maintenance crib, order the quantity you need, one piece per connection.
