FuseBox 63A D Curve 10kA Single Pole MCB | MT10D631

Built for commercial, industrial and three phase distribution, the FuseBox MT10D631 is a single pole 63A D curve MCB rated at 10kA to BS EN 60898.

A 63A D curve device is typically used on sub main feeds to outbuildings and downstream distribution boards. 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.
