Bussmann TB300-07QC5 Eaton TB300 Series Seven-Pole Barrier Terminal Block, 600V

Bussmann TB300-07QC5 Eaton TB300 Series Seven-Pole Barrier Terminal Block, 600V

The Bussmann TB300-07QC5 is a Eaton TB300 series panel-mount terminal block connector engineered for demanding industrial and OEM control wiring. This seven-pole, barrier-style connector features a black molded thermoplastic base with tin-plated brass terminals and zinc-plated steel Phillips-slot screws, and it carries a 7500V breakdown voltage with a 600V, 30A rating for dependable panel-mount performance. With a compact 3.25 x 1.33 x 0.81 IN footprint, it is sized for tight panelboard and control-enclosure layouts where isolated multi-circuit terminations are required. Genuine Bussmann/Eaton manufacturing helps ensure consistent fit, form, and electrical performance for replacement and new-build wiring projects.

Key Features

• Panel-Mount Footprint: Compact 3.25 x 1.33 x 0.81 IN (L x W x H) dimensions for direct mounting inside control panels and distribution enclosures.
• Durable Construction: Molded thermoplastic base paired with tin-plated brass terminals for low-resistance, corrosion-resistant connections.
• Zinc-Plated Steel Hardware: Zinc-plated steel Phillips-slot (philslot) screws resist corrosion and simplify torque-down field wiring.
• Seven-Pole Barrier Design: Seven isolated poles with barrier separation help guard against accidental contact between adjacent circuits, supporting cleaner multi-circuit terminations.
• Electrical Ratings: Rated 7500V breakdown voltage, 600V, 30A for demanding industrial and commercial wiring applications.
• Black Molded Housing: Black thermoplastic housing delivers consistent panel appearance and dielectric strength across the seven-pole assembly.
• Compact, Space-Saving Profile: Low-profile barrier block design conserves enclosure space while keeping each of the seven terminations clearly separated.
