2.8. Product life: more than 10000 times
2.9. Weight:1.7 g
2.10. Action temperature deviations:+-5 degrees
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.
