Rated 5 out of 5 by from Sentry MCB 45Amp Had a little trouble fitting at first. The bottom connection inside the MCB to the bus bar was not as deep as the ones already in the box so it stuck up higher that the others and would not fit on the DIN rail Thought I would have to return it or reduce the size of the busbar leg. Got over it by removing the busbar completely, fitting the new MCB, which now lines up with the rest of them and the dim rail then I reconnected the busbar. The busbar hangs a few mm lower but is fine. Busbar cover fits with no problem, Job done.
