We are now closed for stocktaking and are taking this opportunity to carry out website upgrades and add hundreds more products. All to enhance your future shopping experience with us. We should be up and running again early October 2023.


Check out a variety of obsolete miniature circuit breakers from Protek now available from Zetmet Limited. An MCB is one of the most common ways of protecting an electrical installation from overloads and short circuits.

As with all products we sell our obsolete items are brand new and unused. For this reason stocks can be extremely limited and once they’re gone they’re gone!
