592-EC3FE

The 592-EC3FE module is a solid-state overload relay. It is designed by Allen-Bradley as part of the Bulletin 592 product range. The operating specifications for the 592-EC3FE module include 18 to 90 Amps of current rating. The contactor size for the 592-EC3FE module is 4. The relay is designed for single-phase and 3-phase applications. The relay is shipped from the factory with a programming set for 3-phase operation. Changing the programming for single-phase operation is easy and it can be done by changing the relevant parameter which is Parameter 27. The functions supported by the 592-EC3FE module include warnings for operating hours, warnings for the number of starts, jam, underload, and stall (trip only). The DeviceNet network can be used for monitoring diagnostic parameters, voltage parameters, power parameters, and current parameters.

The voltage parameters which can be monitored on the 592-EC3FE module include the voltage range, phase rotation, voltage warning status, voltage unbalance, and voltage frequency. Diagnostic parameters which can be monitored on the 592-EC3FE module include the trip status, device status, warning status, time to an overload trip (in seconds), and the time to reset after an overload trip (in seconds). The power parameters which can be monitored on the 592-EC3FE module include the power factor, power consumed, power range, reactive power, and the apparent power. Current-based data which can be monitored includes the average current, individual phase currents, current imbalance percentage, and ground fault current. The environmental specifications for the relay include an -40 to 85 degrees Celsius storage temperature range and -20 to 40 degrees Celsius operating temperature range. The relay housing is IP 20 rated and it is designed for convection cooling.
