Thermal relays are used in

Thermal relays are used in Correct Answer Motor starters

The majority of winding failures in a motor is either indirectly or directly caused by overloading, single phasing, and operation on the unbalanced supply voltage. These all factors lead through excessive heating to the deterioration of the winding insulation until an electrical fault occurs.

Thermal overload relays are economic electromechanical protection devices for the main circuit. They offer reliable protection for motors in the event of overload or phase failure

Main benefits of thermal relay:

  • Reliable protection for motors
  • Easy to create starters
  • Optimized match to ABB contactors
  • Single mounting kits and wire reset for remote control available for specific applications
