GE / Alstom P50 Agile P253 Motor Protection

P50 GE Alstom Agile P253 relay provides basic motor protection for small and medium size MV/LV motors. It includes a wide range of measurements for motor supervision and operations including starting current record, and features flexible SCADA communication options such as Modbus/IEC 60870-5-103 or DNP3.0.

The principal protection functions include thermal overload, negative sequence overcurrent, loss of load, prolonged start, locked rotor (starting / normal running), restricted earth fault, excessive number of starts and speed switch input. Additional versatility is provided through backup overcurrent and earth fault protection, with up to 3 independent stages, breaker fail and trip circuit supervision functions. The hardware capability is broadened by a sensitive earth fault CT option.

The user may assign any of the logical/physical statuses to binary inputs, outputs and programmable LEDs. All the output contacts are changeover type for ease of implementing the desired wiring schematic.
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 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.
