Miniature circuit breaker
Overload protection, or miniature circuit breakers (MCBs): ‘…provide the most modern form of electrical current overload protection by detecting a fault condition and interrupting the current flow. MCBs replaced cartridge fuses and the original wire fuses (these simply melt when overheated) which formed the earliest form of protection.’ Ref English Housing Survey, Profile and condition of the English housing stock, 2018-19, Published by the Ministry of Housing, Communities & Local Government in August 2020.
