The switch of the aerator is burnt out, but it will trip forward instead of backward. What happened?
1. For instruments with a forward load greater than the reverse load of the motor, such as water pumps and fans, due to the denaturation or improper setting of the switch thermal element, the set value will change, causing the motor to trip together; When the motor is started in reverse, it is not easy to trip due to low load.
2. When the motor rotates forward, the forward friction of the bearing or machinery of the motor or load is greater than the reverse friction, resulting in the increase of the forward load and tripping, such as equipment with gearbox.
