Bussmann TB300-03SP Eaton TB300 Series Three-Pole Terminal Block Connector, 600V/30A

Bussmann TB300-03SP Eaton TB300 Series Three-Pole Terminal Block Connector, 600V/30A

The Bussmann TB300-03SP is a panel mount terminal block connector from the Eaton TB300 series, engineered for double-row, barrier-style three-pole power connections in industrial control panels and distribution equipment. Built with tin-plated brass terminals secured by #8-32 TPI zinc-plated steel SEMS philslot screws, this black terminal block connector is rated 600V / 30A with a 7500V dielectric breakdown voltage, and manufacturer specification data also lists a 300A amp rating for the assembled block. Compact dimensions of 3.25 x 1.33 x 0.81 IN make it a space-efficient choice for panel-mount terminal wiring in commercial and industrial applications.
