Product reviews
17 amt in aino technology research and development of a patent product, on the basis of the 17 am temperature protector, series of different value of S type or spiral resistance heating element, and bimetallic strip form series protection circuit, can meet the current 1 a to 30 a rapid over current, over temperature protection, it can accurately control the motor blocked or current overload of motor damage, in time of disconnect the circuit of the machine.
Design principle
Automatic reset design principle:
(1) Principle of current overload protection: The heating element inside 17AMT is matched with the bimetal plate. It can not only provide the normal operation of the equipment, but also precisely control the overheat and overcurrent trip time. When the current of the motor and transformer is too large or the blocking current exceeds the jump value set by the thermal protector, the protector can cut off the circuit instantly, so that the electrical appliances can be protected. Design range of current overload trip value: 1A~30A.
(2) Principle of temperature overload protection: The internal bimetal plate of 17AMT can accurately feel the working temperature of the electrical appliance. When the abnormal normal operation such as electrical malfunction, overload and stalling makes the surrounding temperature too high, the quick reaction of the bimetal plate of 17AMT causes the silver contact to break and the electrical appliance circuit to be protected. When the 17AMT is cooled to a safe temperature, the contact is automatically closed and reset.

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.
