Load control:
In fact, in the past and even now, in order to be able to protect the electric motors in the system against dangerous factors such as overload, we used bare metal or thermal switches. If, for any reason, the desired motor requires more than the allowed current from the circuit, the motor power supply path is cut off by using bimetal or a thermal switch to identify the circuit fault. Today, three-phase overcurrent relays (load control) are a suitable replacement for non-metal relays and thermal switches.

The load control relay, having three internal current transformers, measures the current of each of the current channels like an ammeter and compares it with the set current, and if the current of each line exceeds the set value, it removes the consumer from the circuit. . In order to cover the starting time in motors with a lot of overload, an adjustment screw is provided on the relay to adjust the delay time.


Reasons for using overload relays instead of bare metal:

Among the disadvantages of bimetals is that this piece is a mechanical cut and also loses its sensitivity over time and does not work properly. In addition, for each type of contactor, there is a specific bimetal. Also, because bimetals work based on temperature changes, environmental temperature changes can
