Please be aware we are currently not taking any new orders until 22nd March 2023 due to essential maintenance being carried out to the website to future enhance your shopping experience with us. Thanks The Zetmet Team.

Protek

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!
