Structure and Theory of Protection

KSD9700 type heat protector is composed by heat conductive metal shell, double metal component with welded silver alloy contact, current conductive frame, insulated fixing seat, static contact pad and heat resistant wires etc. The fully enclosed structure can prevent the protector from dust or impurity pollution, the infiltration of lacquer and the damage caused by external force. The product is supplied with a heat conductive and temperature resistant insulated bushing for its shell is made of conductive metal. When the current goes through the double metal component with impedance, if the current increases or the environment temperature rises and the temperature reaches the preset value, the double metal component will work and release the contact to shut off the circuit; And by contrast, if the device cools down to the safe temperature, the contact point will close automatically to restore the normal work state.

Applications

K series protectors are double sensitive to current and temperature and are widely applicable to the overheat protection of single or three phase electric motors caused by overload and blocked running. Moreover, the protectors are also applicable to the overheat protection and temperature control of normal electric equipment such as chocking coil, spiral vacuum tube and transformer etc.
