SENTOP TB Series
High-Current Fixed Barrier Terminal Blocks | Robust Power Distribution
Product Overview
The SENTOP TB series is specifically designed for high-power electrical equipment and machine tool manufacturing. These terminal blocks feature a dual-row fixed screw system with a high-transparency protective cover that allows for easy visual inspection while preventing accidental electrical contact. Constructed from high-strength Polycarbonate (PC), the base offers exceptional impact resistance and heat stability (-40°C to +125°C). The conductive parts are crafted from nickel-plated brass to ensure maximum conductivity and corrosion resistance, supporting conductor sectional areas from 1.5mm² up to 25mm².
