Product reviews
The temperature protector of metal shell is a miniature product developed by our company
Diamond structure, small size, easy to install
Motor heat protector/circuit breaker
No flash, accurate operating temperature
A small thermal protector with a metal case
Stable, reliable and long service life can be achieved by non-current-carrying device design
 
Design principle
The structure design is simple, by the strip high sensitive bimetallic element, moving contact, static contact, screw, cover plate and so on composition. The bimetallic element is placed on the bottom shell, the moving contact and the static contact are closed, and the circuit is conductive. When the use of electrical heating, the temperature rises to the rated operating temperature of the product, the bimetal elements are heated to generate internal stress and act quickly, so that the contact is disconnected, power is cut off, the electrical stop working, thus playing the role of overheating protection. When the temperature of the protected electric appliance drops to the rated reset temperature value of the product, the bimetallic element will return to the initial original state and the moving contact and the static contact will close, and the electric appliance will resume working. The protection function of the product can be divided into two types: normally open type and normally closed type, namely, conducting circuit and disconnecting circuit when the temperature reaches the design value.
Due to the use of metal shell, the protector has a stronger mechanical strength, can be covered with an insulating sheath, insulation measures with the metal parts of the motor.
 
 
Range of application
 
Designed for all types of motors, fan motors, washing machines and other small electrical appliances, transformers, ballasts, battery packs, glue breakers, solenoids, electric appliances, etc., which can be used as self-reset thermal circuit breakers (type 2B), motor thermal protectors (type 3C) and ballast thermal protectors.
 
Overall dimensions


Electrical specifications
250 v AC 3 a; 125 v AC 6 a; 24 v DC 6 a;
Reference for number naming



Characteristic curve
The approximation is only used to select the sample for the certification test



These curves are used only to provide guidance when selecting protectors for a particular application. Other factors should be considered when selecting a protector, such as the distance from the heat source and the method of installation. Final trip time depends on terminal configuration and installation conditions.
