温控器

突跳式温控器小型带外壳的双金属片温控器,属温度继电器类器件.利用碟形双金属片在温度作用下产生瞬间跳动的原理,通过机构的作用,使触点迅速动作,达到断开或接通电路的目的.其工作温度固定,无须调整;动作可靠干脆,电弧小;使用寿命长;无线电干扰少.

KSD301 snap action thermostat is a small-size bimetal thermostat series with a metal cap, which belongs to thrmalrelays’ family. The main principle is that one function of bimetal discs is snapping can push the action lf the contacts through the inside structure, then caused on of off the circuit finally. The main characteristics are the fixation of working temperature, the reliable snap action, less flashover, longer working life and less radio interference.
Electric Ratings: AC250V 5A/AC 125V 7A (Resistive load) AC250V/10A (Resistive load)
Electric Strength: No breakdown and flashover under AC 50HZ for one minute
Insulation Resistance:＞1000MΩ(with a DC500V mugger)
Contacts Form: S.P.S.T. D ibis ion to five tubes:
Closes in room temperature.  Opens at temperature rise, closes at temperature decreasing.
Closes in room temperature.  Opens at temperature rise decreasing, closes at temperature rise.
Opens in room temperature.  Closes at temperature decreasing, Opens at temperature decreasing.
Opens in room temperature.  Closes at temperature decreasing, Opens at temperature rise.
Closes in room temperature.  Opens when the temperature rise, Closes at temperature decreasing.
The action lf close will be finished through manual reset. Earthlings Methods: by the connection of the metal cap of thermostat and the earth-connect metal part of appliance
