7AM Temperature Protector

Design Principle

The 17AM+PTC temperature protector is a derivative product of the 17AM temperature protector. A PTC is set on the basis of the 17AM temperature protector. The heating element and the protector contact form a parallel circuit. When the protector is separated from the control, The PTC two poles get voltage and generate heat, which causes the temperature to be conducted to the internal bimetal, causing the contacts to remain in a separated state, and the equipment is in a shutdown state, waiting for the equipment failure to be eliminated or the power supply to be cut off. After the power is cut off, the PTC stops heating, and the 17AM temperature protector can automatically reset after a certain time of cooling down, and the equipment returns to normal state. Therefore, the temperature protector also has power-off protection and delay protection functions at the same time, achieving the function of manual reset, and its protection function is more reliable and complete.

Temperature Specification

Action temperature: 40~180℃±5℃, every 5℃, it is a temperature specification.

Reset temperature: In an environment of 25°C, the thermal protector will not automatically reset after tripping and without power failure. It will automatically reset after a power failure and a delay of 20-30 seconds.


Characteristic Curve

Approximate value is only used to select samples for certification test

Characteristic Curve

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