The Allen-Bradley 592-EC2AC E3 Plus Overload Relay is the part number for an E3 Plus solid-state overload relay device. This device belongs to the Allen-Bradley Bulletin 592 overload relay family. The E3 Plus overload relays are a series of general-purpose, multifunction, microprocessor-based relay switches that are designed to protect single or 3-phase squirrel-cage induction motors. The Bulletin 592 overload relays come in 2 configurations; the E3 and E3 Plus overload relays, and the 592-EC2AC E3 Plus Overload Relay belongs to the E3 Plus category. Like all E3 Plus overload relays, the 592-EC2AC E3 Plus Overload Relay is designed to provide robust ambient compensated overload protection. The 592-EC2AC E3 Plus Overload Relay is DeviceNet-compatible, which means it can connect to the DeviceNet network for enhanced functionalities.
The Allen-Bradley 592-EC2AC E3 Plus Overload Relay also features built-in ground fault sensing for zero sequence (core balance) ground fault protection, PTC thermistor monitoring, and underload protection in addition to several other built-in protective features. Unlike conventional overload relays in its class, the 592-EC2AC E3 Plus Overload Relay features a microprocessor-based overload setting for precise, accurate, and reliable protection. The 592-EC2AC E3 Plus Overload Relay has an adjustable current range of 1 to 5 Amps and an IEC rated maximum operating voltage rating of 690 Volts AC. The overload relay has a contactor size range of 0 to 2 for the Bulletin 500 contactors. The 592-EC2AC E3 Plus Overload Relay has 4 discrete inputs, 2 discrete outputs, and a PTC thermistor input. The 592-EC2AC E3 Plus Overload Relay has a 24 Volts DC rated control circuit with an operating voltage range of 11 to 25 Volts DC and a total power rating of 3.9 Watts.
