Performances and features Of The Manual Reset Bimetal Thermostat
The bimetal is used as the temperature sensing element. When the temperature rises to the operating temperature, the bimetal jumps and the drive contact moves quickly. When the temperature drops to a certain value, the contact does not reset. If it needs to be reconnected, it needs to be used. The force presses the reset handle and the thermostat contacts return to their original state, achieving the purpose of switching the circuit and manually restarting the switch. The utility model has the characteristics of stable performance, high temperature control precision, simple action and small volume, light weight, high reliability, long service life and small radio interference.
Attention Of The Manual Reset Bimetal Thermostat
● This manual reset type thermostat can be pressed by the reset handle after the temperature rises and the temperature drops by 20 °C, and the force is 4-6 Newtons. It should not be too large.
● In order to ensure the normal operation of the thermostat, the vertical distance from the end face of the reset handle to the temperature sensing surface of the cover is not less than 20.4mm.
