Bussmann TB300-0500ST Eaton TB300 Series Five-Pole Barrier Terminal Block, 600V, 30A

Bussmann TB300-0500ST Eaton TB300 Series Five-Pole Barrier Terminal Block, 600V, 30A

The Bussmann TB300-0500ST is a genuine Eaton TB300 series panel mount terminal block connector engineered for reliable five-pole barrier-style wiring connections in industrial and commercial electrical systems. Rated 600V and 30A with a 7500V breakdown voltage, this terminal block delivers dependable dielectric strength and current-carrying capacity for demanding panel-mount applications. Construction includes a black molded thermoplastic base for insulation, a tin-plated brass terminal for low-resistance conductivity, and a stainless steel Phillips-slot screw for a secure, corrosion-resistant termination. Compact dimensions of 3.25 x 1.33 x 0.81 IN (L x W x H) allow the TB300-0500ST to fit efficiently within control panels, junction boxes, and distribution equipment where space is limited.
