25A Big Current Electric Heater Snap Disc Thermostat Bakelite
KSD302 25A Big Current Bakelite overheating protection electric
heater thermostats with CQC/TUV
The main principle is that one fumction of bimetal discs snap
action under the change of sening temperature.The snap action of
disc can push the action of the contacts through the inside
structure,then caused on of off of the circuitfinally.The main
characteristics are the fixation of working temperature,the
reliable snap action,less flashover,longer working life and less
Rapid heat transmission.
No breakdown, no flashover.
Every product will be tested, extremely high temperature pass rate.
Being used the bimetal disc as temperature response element. It
will be deformed when the bimetal disc reach a definite
temperature. The snap action of bimetal disc can separate the
contactor quickly and cut off the power to protect the appliances
or electrical equipments.
