FuseBox 25A D Curve 10kA Triple Pole MCB | MT10D253

Built for commercial, industrial and three phase distribution, the FuseBox MT10D253 is a triple pole 25A D curve MCB rated at 10kA to BS EN 60898.

As a triple pole device it disconnects all three poles together, making it suited to three phase motors, heaters and sub main feeds. The D curve characteristic trips magnetically between 10 and 20 times rated current, intended for very high inrush loads such as large motors, welders and transformers. Final device selection should always follow the circuit design, cable size, installation method and fault level of the installation.
