FuseBox 25A B Curve 10kA Triple Pole MCB | MT10B253

Rated at 25A with a B curve characteristic, the FuseBox MT10B253 3P MCB gives 10kA overcurrent protection in FuseBox consumer units and TPN distribution boards.

As a triple pole device it disconnects all three poles together, making it suited to three phase motors, heaters and sub main feeds. The B curve characteristic trips magnetically between 3 and 5 times rated current, the usual choice for domestic final circuits with resistive and general loads. Final device selection should always follow the circuit design, cable size, installation method and fault level of the installation.
