Thermal overload relays

Motor protection for overload and phase failure

Thermal overload relays are economic electromechanical protection devices for the main circuit. In combination with contactors, they provide reliable protection against overloads and phase failures for motors. They allow to set up customized motor starting solutions according to individual needs.

Main benefits

  • Reliable protection for motors in the event of overload or phase failure
  • Easy creation of individual motor starting solutions
  • Perfect fit to ABB’s contactors: directly mounted and connected without further wiring
  • Single mounting kits and accessories for remote control available for specific applications
  • Selectable automatic reset mode allows to reduce downtimes and travelling costs
  • In combination with ABB mini contactors, the installation in narrow spaces is possible
  • Rated for AC and DC loads

Main features

  • Trip class 10/10A
  • Adjustable current setting ranges
  • Overload protection with phase loss sensitivity
  • Temperature compensation up to +70°C
  • Selection between automatic or manual reset mode
  • Stop and test function
  • Finger safe housing (IP20)
  • Large markings on setting scale for precise setting
  • Suitable for 1-phase applications
