Matching contactors and thermal overload relays

The contactor's rated current must cover the motor duty, and the relay's setting range must match the actual load. Estimating from motor kW alone tends to fail on heavy-duty starting.

  • Select by utilisation category (AC-3 / AC-4)
  • Check coil voltage and the control circuit
  • Allow clearance for heat dissipation and mounting
