KSD301 1/2″ Snap Action Bimetalni disk termostat
1. KSD301 1/2″ Snap Action Bimetal Disc Thermostat Principle and structure
The main principle of KSD series thermostat is that one function of bimetal discs is snap action under the change of sensing temperature. Snap akcija diska može gurnuti radnju kontakata kroz unutrašnju strukturu, a zatim na kraju izazvao u krugu. The main characteristic are the fixation of working temperature, the reliable snap action, less flashover longer working life and less radio interference.

3. Difference of auto reset type and Manual reset type
3.1. Manual reset type: Temperature sensing components consist of bimetallic strip. When the temperature reached the action temperature range, it will jump quickly and the movable disc disconnects. When the temperature declines to a fixed temperature point, the contact point cannot reset until reconnecting the circuit by pushing the reset button. And then the contact points recover, reaching a purpose of connecting or disconnecting the circuit and restarting the circuit by manual reset. (Kindly reminder: 1.This type of manual reset thermostat can reset when the temperature declines 20 °C after snap action by pressing the reset button. And 4~6 N will be advisable; please don’t use too much strength. 2. To ensure the normal function, the distance between the reset button and the close cover should not be less than 20.4mm. )
3.2. Manual reset type: Temperature sensing components consist of bimetallic strip. When the temperature reached the action temperature range, it will jump quickly and the movable disc disconnects. When the temperature declines to a fixed temperature point, the contact point can auto reset and start working.
