Product Overview
Overview
The E300™ Electronic Overload Relay is a microprocessor-based electronic
overload relay designed to protect three-phase or single-phase AC electric
induction motors rated from 0.5…65,000 A. Its modular design, communication
options, diagnostic information, simplified wiring, and integration into Logix
makes this 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
Users can select the specific options needed for their motor starter application.
The E300 Electronic Overload Relay consists of three modules: sensing, control
and communications. Users have choices in each of the three with additional
accessories to tailor the electronic motor overload for their applications exact
needs.
Wide current range
Sensing capabilities (Current, Ground Fault Current, and/or Voltage)
Expansion I/O
Operator interfaces
Communication Options
Users can select from multiple communication options which integrate with
Logix based control systems. Developers can easily add the E300 Electronic
Overload Relay to Logix based control systems using Integrated Architecture
tools such as Add-on Profiles, Add-on Instructions, and Faceplates.
