SENTOP TD Series
Combined Rail-Type Terminal Blocks | High-Current Power Solutions
Product Overview
The SENTOP TD Series is a premium combined terminal block system designed for high-current industrial wiring. These blocks feature a unique combination of polycarbonate insulation and nickel-plated brass conductors, offering exceptional heat resistance, anti-aging properties, and superior conductivity. The screw terminals utilize a composite groove process, making them compatible with both straight and cross screwdrivers. Equipped with a transparent, removable protective cover, the TD series allows for safe visual inspection and easy maintenance in control panels and power distribution systems.
