KSD301 and KSD302 thermostat product image Close-up view of thermostat internal components

The KSD series thermostat operates on the principle of bimetallic discs that snap into action when temperature changes occur. This snap action activates the internal contacts, ultimately controlling circuit connections. Key features include fixed working temperature settings, reliable snap action, minimal flashover, extended operational lifespan, and reduced radio interference.

KSD301 Auto Reset vs Manual Reset Types
Manual Reset Type: Temperature sensing components consist of bimetallic strip. When temperature reaches the action range, it snaps quickly and the movable disc disconnects. When temperature declines to a fixed point, contacts cannot reset until the reset button is pressed manually. This allows circuit reconnection and restart.
  • Manual reset thermostats can reset when temperature declines 20°C after snap action by pressing reset button
  • Recommended force: 4-6 N (avoid excessive strength)
  • Ensure minimum 20.4mm distance between reset button and close cover for normal function
Auto Reset Type: Temperature sensing components consist of bimetallic strip. When temperature reaches the action range, it snaps quickly and the movable disc disconnects. When temperature declines to a fixed point, contacts automatically reset and resume operation.
