Description:
Model KSD9700Bimetal Thermal Protector is composed of high
sensitive disk-shaped bimetallic element,moveable
contact,static contact plate, fixed baseplate, moveable spring
plate, case and temperature resistance lead wire.The
bimetallic strip is fixed on the baseplate, which can maintain
the consistency of disconnection and reset temperature after
long-term use. Its main working principle is to control the
temperature by opening or closing the bi-metal strip. It stays at
normally closed/normally open status, it opens/closes when
temeprature rising and closes/opens when temperature decreasing.It
protects the device overheating and burning out. At normal
temperature, the moveable contact and the static contact
are in the closed state, the circuit is on.When the use of
electrical failure, the temperature rise to the rated disconnect
temperature value of the product, the bimetal element heat produced
internal stress rapid action, it push the contact and cut off the
power supply, then the electrical appliances stop working, so as to
play a protective role.When the temperature of the protected
appliance drops to the safe temperature, switch on the power again
and the appliance resumes working.
