Blackburn STB110A1304 FLEX BRAID TNCU 1100A 2H 304MM

It's a flexible flat braid shunt connector, tin-plated copper, rated 1100A, with a two-hole pad at each end and a 304 mm braid length. Connectors like this carry current across a moving or expanding joint, typically switchgear, disconnect blades, breaker connections and bus expansion points, where a rigid bar would fatigue. It's built to IEEE/ANSI C37.34, the standard for switchgear-type flexible connectors.

It's built to IEEE/ANSI C37.34, which is the standard specified for high-voltage air switch and switchgear flexible connectors. If your drawing calls for a C37.34 flexible shunt at 1100A with a two-hole terminal pad, this one answers that line.

1100A is the published current rating on this braid connector. Ampacity on a flexible shunt assumes the pads are properly torqued to clean, flat contact surfaces and that the braid is not bunched or restricted; a pinched or over-bent braid loses the airflow the rating depends on.

The conductor is tin-plated copper. Tin plating slows oxidation on the braid strands and on the bolted pad faces, which keeps contact resistance from creeping up over time, and it's the usual choice where the connector lands on aluminum or plated bus rather than bare copper.

Not where there's movement. The braid is flexible and flat by design, which lets it absorb thermal expansion, vibration and the travel of a switch blade without stressing the bolted joints. A rigid bar in that position transfers every bit of that movement into the pads and the equipment terminals. Use a solid bar only on a fixed, non-moving connection.

It ships as each, one connector per unit. Shunts are almost always installed in sets across a joint, so order the count your assembly needs rather than assuming a pair comes in the box.

Country of origin is the United States. That matters if you're buying for a government, utility or federally funded job with domestic-content language in the purchase order.
