E100 Electronic Motor Overload Relay

The new Allen-Bradley™ E100™ Electronic Motor Overload Relay can help customers better protect their motors and avoid unplanned downtime due to motor failure. As the next generation of Allen-Bradley basic-tier electronic overload relays for our scalable solution portfolio, it more accurately measures a motor’s current load, models its temperature and can de-energize the motor to help minimize potential equipment damage due to overheating.193 E100 Relays

The E100 overload relay is part of the Rockwell Automation integrated motor control system. It can mount directly to bulletin 100-C IEC, 100-E IEC, 300 NEMA (energy-saving), and 500 NEMA contactors up to 100 A. The E100 basic model has two user-adjustable trip class settings of 10 and 20. 

Features & Benefits:

  • 5:1 wide current adjustment range to cover a variety of motor applications in a single device
  • Trip class 10, 15, 20 and 30 (selectable) to cover a wide range of motor applications, 10 and 20 in the basic version
  • 48% footprint reduction using pass-thru solution
  • Agency recognized certification strategy across portfolio
  • Accurate and repeatable settings to help minimize commissioning time
  • Higher efficiency and low heat dissipation versus traditional eutectic or bimetal relays
  • Pass-thru minimizes number of power terminal connections
  • Built-in thermal memory and phase loss detection helps protect your motor investment
Optional accessories and expansion modules can extend the functionality of the E100 overload relays, enhancing motor overload protection while maintaining a cost-effective solution.

Additional Capabilities with Accessories:

  • Jam & Ground Fault Protection
  • Electronic Remote Reset
  • Status Indication Display
  • Anti-Tampering Shielding
