Blackburn STB070A1457 – Frequently Asked Questions
1) What current is the Blackburn STB070A1457 braid connector rated for?
It is a 700 amp flexible braid, built as a flat tin-plated copper conductor. Size the braid to the continuous current of the bus or switch connection it is bridging, not to the breaker frame size alone.
2) Does this Blackburn flexible braid meet a recognized switchgear connector standard?
Yes. The STB070A1457 is built to IEEE/ANSI C37.34, the standard covering high-voltage air switches and their connectors. That is the citation a utility or institutional spec writer usually wants on a flexible braid shunt.
3) How many bolt holes are on each end of the STB070A1457 braid?
It is a 2-hole braid connector, so each flat terminal pad takes two bolts. Two-hole pads resist rotation under torque and vibration, which matters on a switch or bus connection that will be cycled. If your existing pads are drilled for a single bolt or for a four-hole NEMA pattern, this braid will not line up.
4) Why use a flexible braid shunt instead of a solid copper bus bar link?
A braid is the right choice where the two connection points move relative to each other, from thermal expansion of a bus run, equipment vibration, or the travel of a disconnect blade. The STB070A1457 is a flexible flat conductor, so it absorbs that movement instead of transmitting it into the terminal pads. A rigid bar is fine only where both ends are fixed and aligned.
5) Is the braid tinned, and does that matter for connecting to aluminum bus?
The conductor is tin-plated copper. The tin plating slows oxidation on the copper strands and is the usual finish specified when a copper connector lands on aluminum bus or lugs. Use a joint compound rated for the metals involved and torque to the equipment manufacturer's figure for the pad.
6) Is the Blackburn STB070A1457 sold individually or in a pack?
It ships as a single braid, sold each, under manufacturer part number STB070A1457. If you are shunting both sides of a two-pole or three-pole arrangement, order one per connection point.
