Bussmann TB300-12SPL1 Eaton TB300 Series 12-Pole Barrier Terminal Block, 600V, 30A

The Bussmann TB300-12SPL1 is a panel-mount barrier terminal block connector from the Eaton TB300 series, engineered for dependable circuit termination in industrial and commercial control panels. This black, twelve-pole terminal block carries a 600V, 30A rating per pole along with a 300A amp rating and a 7500V breakdown voltage rating for an added dielectric safety margin. Tin-plated brass terminals paired with zinc-plated steel SEMS Philslot screws provide a corrosion-resistant, vibration-resistant connection point for panel wiring, while compact 3.25 x 1.33 x 0.81 IN dimensions keep the footprint efficient inside crowded enclosures.

Key Features

  • Compact Panel-Mount Footprint: Measures 3.25 x 1.33 x 0.81 IN, sized for efficient mounting inside control panels and enclosures.
  • Twelve-Pole Barrier Configuration: Twelve individual poles with insulating barriers help prevent arcing between adjacent circuits.
  • Tin-Plated Brass Terminals: Corrosion-resistant plating supports dependable, long-term electrical contact at each pole.
  • Zinc-Plated Steel SEMS Screws: Philslot SEMS hardware combines the screw and washer into one captive fastener for faster, vibration-resistant wire termination.
  • Voltage & Current Rating: Rated 600V, 30A per pole for control and power wiring circuits.
  • 300A Amp Rating: Block-level 300A amp rating supports higher-capacity panel wiring applications.
  • 7500V Breakdown Voltage: High breakdown voltage rating provides added dielectric strength and safety margin.
  • Black Insulating Housing: Molded black barrier body separates and protects each terminal pole from its neighbors.
