MK 80 AMP 30mA DOUBLE POLE RCD K5780S SENTRY

MK stopped making these three years ago. They are now made under licence by a company called Circpro in China. However, Circpro ones have a Y or H prefix whereas original MK ones have a K prefix. So if you get one with a K prefix then it is most likely old MK stock, though I received mine in a box with the H prefix
