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.

MK

Numerous MK Residual Current Devices from the now discontinued “Sentry” range are available from Zetmet Limited. All RCD’s are designed to monitor the flow of electrical current through a circuit thereby providing protection against an array of faults.

Many of the products in our obsolete section are rare or discontinued. Therefore, stock levels can be extremely limited so act fast as once they’re gone they’re gone!
