The P154 is an economical choice, designed for deployment in volume, in lower-voltage systems. It offers non directional over current and earth fault protection, with its functions designed to cover a wide range of applications in the protection of cables and overhead lines deployed in industrial installations, public distribution networks, and substations. The P253 is designed to protect motors in industrial networks and power plants. It offers essential protection functions for motors deployed in installations from LV to MV voltage levels. The P253 relay performs an important role in many industrial processes with its diagnostic features improving asset health monitoring. The P154 and P253 relays offer supervision features such as measurement, monitoring and recording functions. Communication protocols are available for transmitting relay data to a supervisory control system via communication networks. The operator interface allows reading of measured values and simple configuration of the relay. The setting software
facilitates configuration and access to all the stored information for monitoring, maintenance and troubleshooting purposes. P154 and P253 relays are housed in a robust metal case suitable for panel mounting.
