Blackburn EXH140A11200 EX-FLEX BRAID TNCU 1400A 4H 1200MM

It's a flexible braid connector for substation and switchgear bus work, rated 1400A, used where a bus run needs to absorb thermal expansion, vibration, or slight misalignment between rigid conductors. The braid is tin-plated copper in a flat conductor shape, built to IEEE/ANSI C37.34. It sells each, so one piece is one connection.

It's a 4-hole connector, so each end pad takes four bolts. Match that against your bus bar drilling before ordering; a 2-hole pad on the existing bus will not accept this terminal without adapting the connection.

Yes. The braid is rated 1400A, so it carries a 1200A bus with margin. Sizing a flexible connector at or above the continuous bus rating is standard practice, and the tin plating on the copper helps keep contact resistance stable at the bolted joint.

A rigid link transmits every bit of thermal growth, breaker operation shock, and seismic movement straight into the adjacent equipment terminal. A flexible braid absorbs it. This one is a flexible, flat-shape braid built to IEEE/ANSI C37.34, which is the switchgear standard, so it's the part you use at breaker and disconnect terminations rather than on a straight fixed run.

No hardware is part of the item. It is sold each as the braid with its 4-hole terminal pads, so plan on supplying your own bolts, nuts, Belleville washers, and any joint compound your spec calls for, sized to the existing bus drilling.

Country of origin on the EXH140A11200 is the United States, which is what utility and government procurement typically needs documented on substation connectors. The part number to reference on the submittal is EXH140A11200.

Tin plating is exactly what you want at a copper-to-aluminum joint. Bare copper against aluminum galvanically attacks the aluminum; the tin surface on this braid is the standard mitigation, used with an appropriate joint compound. The conductor underneath is copper, so ampacity is unaffected by the plating.
