Low voltage protection means that the low voltage protection relay is connected in parallel at both ends of the power supply. When the voltage is low, it will automatically trip to separate the circuit breaker switch. Low-voltage internship installation: low-voltage equipment such as thermal relays, fuses, and intermediate relays.

When the voltage of the power supply bus of the motor is reduced or interrupted and restored, the low voltage protection is usually installed on the secondary motor to prevent the motor from being automatically started at the same time. When the power supply bus voltage is low to a certain value, the low voltage protection action removes the secondary motor and restores the power supply bus voltage to a sufficient voltage to ensure the self-starting of the important motor.
