Rated 5 out of 5 by from MK Type B MCB's My original MK's lasted 25 years. I replaced some with 1£ cheaper model which failed in 5 years. MK's for me again as the value for money speaks for itself.

Rated 4 out of 5 by from Its an MK MCB! Does what it is supposed to! Hopefully install and forget. Regrettably a 16A MCB that I purchased with the consumer unit failed and had to be replaced within 20 months
