Operating principle of thermal overload relays

Motors are one of the most valuable components on any machine. For this reason, machine builders need to take every precaution to protect them. Thermal overload relays are probably the most effective protective devices available on the market you can use to protect your motors. In conjunction with a complementary main contactor, thermal overload relays can monitor and eliminate harmful overcurrent that would otherwise damage your motors.

Applications for thermal overload relays:

  • Motor overload
  • Phase failure
