  1. Hello Sir ,

    What is the importance of overload relay in the system ?
    I am waiting to hear from you.Thank you in advance.

    1. In case motor Amps increase then overload safety is working and open the control circuit save motor winding and Short circuit etc..

  2. The Overload switch that you wire in to the motor it there to protect your motor from working to hard. This switch will measure the amount of electricity (amps) the Electrical motor is drawing. Call Your local Electrician Pretoria for advice on how much an electrical motor can draw. Most of the time the Electrician motor will have a name plate on it stating what the normal amps is.
