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!
