Protector de sobrecarga de motor bimetálico pequeño

The necessity of motor overload protection:

When the motor is running, it is generally allowed to overload for a short time (the output power exceeding the rated value is called overload). Sin embargo, if the overload time is too long and the temperature rise of the motor exceeds the allowable value, it will cause insulation aging, shorten the service life, and even burn the windings in severe cases. Por lo tanto, in order to prevent damage to the motor due to long-term overload operation, the overload time must be limited. This protection is overload protection.

Generalmente, 5AP/2MP/6AP se utiliza como dispositivo de protección contra sobrecarga del motor.. Cuando está en uso, conectar el elemento térmico (trifásico o bifásico) del protector de sobrecarga en serie con el circuito principal del motor. Conecte el contacto principal del relé térmico al circuito de la bobina del contactor en serie..

When the motor overload operation, the current is increased, the heating element temperature rises, the bimetal gently curved, and thus exceeds the predetermined value, and finally open the normally closed contacts, so that the motor coil is deenergized. So as to cut off the power of the motor and avoid the motor from being burnt due to long-term overload operation.
