Hi, If you are referring to a 32A MCB then yes a 32A Crabtree Starbreaker MCB (Screwfix code 90391) will fit this unit but whether this is the correct MCB to use depends on what the MCB is feeding. We recommend that you consult a qualified electrician. Thanks for your interest in Crabtree products.
