The 193-EC1EE relay is an electronic overload relay component that is an important part of multiple industrial systems. The unit is an E3 relay variant that has been designed and developed by Allen-Bradley/Rockwell Automation. The Bulletin 193-EC overload relays like this one are available in different configurations and they have a current range of 0.4 to 5000 Amps. Besides that, the 193-EC relays have LED indicators, test/reset buttons, integrated inputs/outputs, warning settings, several diagnostic functions, true RMS current sensing, and ambient temperature compensation. The 193-EC1EE overload relay comes with thermal overload protection that includes the thermal memory, time to trip, adjustable settings, thermal utilization, and time to reset functions. Also, the relay unit has protection from phase loss, ground faults, stalling, underload, and over-temperature situations.

The 193-EC1EE overload relay supports DeviceNet communication and it can be used with a configuration terminal that provides an additional functionality. The 193-EC1EE relay has 2 inputs and a single output, along with functions specifically used for current monitoring. The users can follow operational data through the DeviceNet network and they can also access information like the hours of operation, history, trip snapshot, and trip status information. All of these functions contribute to easy maintenance and more efficient machine operation. The 193-EC1EE overload relay unit supports a contactor size of C60 to C85 and it has an adjustable current rating of 18 to 90 Amps. This E3 relay component has a rated frequency of 20 to 250 Hertz and a rated insulation voltage of 690 Volts AC. The unit is CSA approved and it is certified by the CE, ABS, CCC, and C-tick standards.
