Blackburn EXH150A1440 – Frequently Asked Questions
1) What is the Blackburn EXH150A1440 flexible braid connector used for?
It is a flexible braided shunt connector, rated 1500 amp, used to carry current across a joint that has to move, flex, or tolerate thermal expansion, typically on switchgear, disconnects, bus runs, and transformer terminations. The braid is tin-plated copper in a flat conductor shape with a four-hole pad on each end for bolted bus connection. Sold individually.
2) How does the four-hole pad mount to my bus bar?
Each end of the EXH150A1440 terminates in a flat pad drilled with four holes for through-bolting to a bus bar or switch terminal. Bolts, washers, and Belleville hardware are not part of the connector, so order them with the job. Match your existing pad bolt pattern before you buy, since a four-hole pad will not land on a two-hole drilling.
3) Does this Blackburn flexible connector meet a recognized switchgear standard?
Yes. The EXH150A1440 is built to IEEE/ANSI C37.34, the standard covering high-voltage air switches and their current-carrying parts. That is the reference a utility or substation spec usually calls out for flexible shunt connectors.
4) Why tin-plated copper braid instead of bare copper for a bus connection?
The tin plating on the EXH150A1440 braid resists oxidation at the bolted pad, which keeps contact resistance stable over time and makes it compatible with aluminum bus hardware where bare copper would be a galvanic concern. The conductor itself is copper, so conductivity is unaffected.
5) Is this braid flexible enough for a moving switch blade or expansion joint?
It is classed as a very flexible conductor, which is the category used where the connection has to articulate repeatedly, such as a disconnect blade hinge or an expansion point on a bus run. A solid or semi-rigid link would fatigue in that service; a braid of this class is made for it.
6) Can I use a 1500 amp braid connector on a lower-rated circuit?
Yes. The EXH150A1440 is rated 1500 amp, and a connector rated above the circuit ampacity is acceptable; the limitation runs the other way. The practical constraints are physical: the 440 mm length has to suit your span, and the four-hole pad has to match your terminal drilling.
7) Where is the Blackburn EXH150A1440 made?
Made in the United States, which matters if your project carries a domestic-content requirement such as a federal or utility procurement clause.
8) Is the EXH150A1440 sold individually or in a pack?
Individually, one connector per unit. If you are replacing braids across all three phases, order the quantity you need.
