Overload Relays

Eaton offers a wide range of overload relays to provide full motor protection. The overload relay types include fixed bi-metallic, interchangeable heater bimetallic, and electronic. Flexible mounting ensures that they can be installed on a contactor, panel, or separate enclosure.
Bimetal relays - Z overload relays up to 630 A 
Bimetal relays - Z overload relays up to 630 A
  • Protection with phase loss and overload
  • Auxiliary contacts switch off the motor protection and signal the fault
  • Suitable for protection of EEx e-motors
  • Optimized for the xStart concept
  • The overload relay Z can be mounted directly on contactor DIL M up to 250 A
  • Separate mounting of the relay possible
ZEB electronic overload relays up to 1500 A

ZEB electronic overload relays up to 1500 A
  • Solution for enhanced motor protection
  • Self-supplying electronics avoids need for connection of an external supply voltage
  • Reduced number of variants reduces inventory costs and simplifies selection and engineering
  • Adjustable tripping classes for optimum protection at varying starting conditions
  • Can be mounted directly on contactor DILM results in space savings in the control panel
  • Automatic / manual release for fast process restart for enhanced availability
  • Adjustable single-phasing sensitivity for symmetric and asymmetric loads
  • Device LED for visual overload early warning
  • Integrated earth-fault current detection  
EMT6 thermistor overload relays 
EMT6 thermistor overload relays
  • Protects machines against overtemperatures during severe starting duty, braking duty, undervotage and overvoltage, and high operating frequency
  • Temperature monitored directly on the motor winding
  • Signal is passed to the EMT 6 in the event of an overtemperature
  • Additional areas of application: Monitoring of temperatures in bearing, gearboxes, oils and coolants
