Selection of safety rated control relays

1) For motors with poor overload capacity, the rated current IRT of the thermal element is 60%-80% of the rated current IN of the motor.

2) In infrequent starting occasions, if the starting current of the motor is 6 times its rated current and the starting time does not exceed 6 seconds, safety control relays can be selected according to the rated current of the motor.

3) When the motor is a repetitive and short-time work system, attention should be paid to determining the operating frequency of the relay. For motors with higher operating frequency, it is not advisable to use the motor as overload protection.
