P&B Engineering Design and manufacture a complete range of LV & MV Motor, Generator and Transformer/Feeder Protection relays. THE MODULAR SUPERVISION & MICROVISION SERIES arguably provides the most complete system of Intelligent Protection and Control available today. We can support and commission alternate communication routes to DCS or SCADA equipment e.g. RS232, 485, 422, Optical fibre and Ethernet. Our products support protocols like P&B Network Gold, MODBUS RTU and Profibus. Our Gold’s relays have been an industry standard for 60 years and are acknowledged as probably the best Electromechanical Motor Protection ever made. We believe that our strong development ethos and our present range of Microprocessor based alternatives to Gold’s will ensure that we will remain competitive and to our valued customers a credible and independent source of Electrical Protection and Control.
