Special features of KSD301 Thermostat
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 ℃ 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. )
