Petit protecteur de surcharge de moteur bimétallique

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). Cependant, 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. Donc, 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.

Généralement, 5AP/2MP/6AP est utilisé comme dispositif de protection contre les surcharges du moteur. Lors de l'utilisation, connecter l'élément thermique (triphasé ou biphasé) du protecteur de surcharge en série avec le circuit principal du moteur. Connectez le contact principal du relais thermique au circuit de la bobine du contacteur en série.

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.

[Modèle]: 5AP/2MP/6AP/ 3MP+PTC/2AM/
