Working Principle of Thermostat-emergency shutoff KSD302R protective 25A 45A thermal protection for boilers
Bipolar jump thermostat is a bimetal thermostat with a shell. The use of disc-type bimetallic film in the role of the moment under
the principle of instantaneous beating, through the role of mechanical structure, so that the two groups of contacts quickly
action to achieve the same time to disconnect or turn on the purpose of bipolar circuit.
Instruction
1. Grounding: The metal cover of the temperature controller is connected to the ground metal parts of the device.
2. The thermostat should work in the general indoor environment where the relative humidity of the air is not greater than 90%,
non -corrosive gas, flammable gas and electric conductive dust exist.
3. When the thermostat uses contact with the temperature, the cover should be covered with the heating part of the charged
appliance, and the thermal conductivity of the heating silicon grease or other performance should be applied on the cover of the
temperature.
4. The top of the cover cannot be crushed or deformed to avoid changing the temperature or other performance.
5. Do not let the liquid penetrate inside the thermostat! The shell must avoid excessive power to prevent cracks; the shell should
be kept clean to prevent pollution of conductive substances, so as to avoid short -circuit penetration due to the reduction of
insulation performance.
6. The use process cannot bend the wiring terminal, otherwise it will affect the reliability of electrical connection.
