Product Overview
Overview
The E300™ Electronic Overload Relay is a microprocessor-based electronic
overload relay that is designed to help protect three-phase or single-phase AC
electric induction motors that are rated from 0.5…65,000 A. Its modular design,
communication options, diagnostic information, simplified wiring, and
integration into Logix makes the E300 the ideal overload for motor control
applications in an automation system. The E300 Electronic Overload Relay
provides flexibility, reduces engineering time, and maximizes uptime for
important motor starter applications.
Modular Design
You can select the specific options that you need for your motor starter
application. The E300 Electronic Overload Relay consists of three modules:
sensing, control, and communications. You can customize each of the three with
accessories to tailor the electronic motor overload for your application’s exact
needs.
• Wide current range
• Sensing capabilities (Current, Ground Fault Current, and/or Voltage)
•
Expansion I/O
• Operator interfaces
Communication Options
You can select from multiple communication options that integrate with Logix-
based control systems. Developers can easily add the E300 Electronic Overload
Relay to Logix-based control systems using Integrated Architecture tools like
Add-on Profiles, Add-on Instructions, and Faceplates.
• EtherNet/IP (DLR)
• DeviceNet
