Electronic Overload Relays: E100 & E300


The E100 Electronic Overload Relay is the next generation basic-tier electronic overload relay. It has enhanced features to better safeguard your motor protection investments, including increased accuracy and repeatability, a self-powered design with lower heat dissipation, and the certifications to comply with many applications. The E100 portfolio is available in two offerings: a Basic (Cat. No. 193-1EE) and Advanced (Cat. No. 193-1EF, 592-1EF) version, supporting both single- and three-phase operation in a single component. The Basic version allows adjustable trip current, manual trip reset, and limited trip class selection. The Advanced version offers the same adjustable trip current, manual and automatic trip reset, a larger selection of trip classes, and the ability to connect additional accessory modules.  


  • Electronic overload detection 
  • Test and reset buttons 
  • Simple configuration 
  • Automatic (193/592-1EF only)/manual reset selection 
  • Selectable trip class 
  • RMS current sensing (50/60 Hz)
