GE/ ALSTOM MOTOR PROTECTION RELAY AGILE P253 NUMERICAL RELAY

The P50 Agile P253 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.
