The Allen-Bradley E100 Electronic Motor Overload Relay is designed to help industrial companies better protect their motors and avoid unplanned downtime. As the next generation of Allen-Bradley electronic overload relays, it is made to more accurately measure a motor’s current load, model its temperature, and shut the motor off when it’s in danger of damage due to overheating.
Options are available to immediately detect jams and ground faults, which should enable faster responses to these specific conditions. A remote reset option is also available for customers to remotely reset the overload.
The E100 overload relay comes in basic and advanced configurations. The basic model has two user-adjustable trip-class settings of 10 and 20. The advanced model has four trip class settings: 10, 15, 20 and 30. Designed for a sensing range of more than 100A, the advanced model should be able to use external current transformer configurations to achieve a maximum rating of 800A.
The E100 overload relay is part of the Rockwell Automation integrated motor control system. It is made to mount directly to bulletin 500 NEMA contactors and 100-C IEC contactors up to 100A.
