Following in the footsteps of the range of retrofit / replacement circuit breakers supplied by P&B over the last 20 years we have embarked on a programme of introducing direct plug and play retrofit relays. This began with introducing state of the art replacements for P&B’s wealth of electromechanical relays and is extending into supplying replacements for relays supplied over the years by other manufacturers. In our latest installation we have replaced obsolete Switchgear and Instrumentation (S&I) Motor Manager5 relays for PDO in Oman. To the delight of this and other customers, not only do they get improved protection relay functionality but improved control and communications as well using the P&B direct replacement.
