Manual reset thermostats use PTC element

Application

Features

Parameter

Used in the manual reset type thermostat

PTC elements and thermostat contact form a parallel circuit, when the temperature increases, higher than the rated breaking temperature, contact circuit disconnect, current loop are formed by PTC element, PTC heating up quickly, higher than the rated reset temperature thermostat, have kept circuit disconnect state, only when shut off the main power supply, the temperature drop to reset temperature of the bimetallic strip, the contact will be closed, more safety and reliable. New electronic production of this kind of PTC ceramics has the following features:

1 warming rapidly, make sure the thermostat contacts keep off state;

2 high voltage to ensure the safety of the thermostat;

3 temperature range, the surface temperature from 95 degrees to 95 degrees, is suitable for different temperature thermostat;

4 life is long, can reach more than 10 years;

Most of the product have UL certification
