Application:

17AMCurrent and temperature double control is a kind of thermal protector with temperature and over-current protection function.

17AM+PTCCurrent and temperature double control series thermal protector is a heating element, It is arranged on the basis of 17AM current and temperature double control Thermal protector, which has power-off protection, delay protection function, The protection function is more reliable and safer.

Working principle:

When the electrical work is abnormal, causing the surrounding Temperature is too high or current overload, double metal piece will act Quickly, so that the two contact is broken, cut off the circuit. When the Temperature drops to the reset temperature, the product is reset and the Circuit is switched on. In the case of a locked rotor, the combination of Bimetal and resistance heating wire provides very accurate breaking time and Maximum protection.

When the product is assembled with PTC, the voltage applied to the PTC element, and the PTC generates enough heat to keep the protector in a Skip state. Only when the power is cut off, the product can be reset, (with Manual reset function).

Selection parameter:

Range of Action temperature: 50C180C
Temperature tolerances:5,8
Locked rotor current: 460A
Jump time:2S12S (Can Be customized according to customer requirements)
