Temperature Controlled Switch KSD301 250V16A Temperature Controller
KSD301 Bimetal Thermostat Temperature Controlled Switch with Normally Closed or Open Auto or Manual Reset UL/CQC/TUV/RoHS Certified

The KSD series thermostat operates on the principle of bimetal discs that snap into action when temperature changes occur. This snap action activates the internal contacts, ultimately connecting or disconnecting the circuit. 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 is achieved through bimetallic strips. When temperature reaches the action range, the mechanism snaps quickly and the movable disc disconnects. The contacts cannot reset automatically when temperature decreases to the fixed point; instead, the circuit must be manually reconnected by pressing the reset button to restore contact functionality.

Important Notes for Manual Reset Type:
  • This thermostat can reset when temperature declines 20°C after snap action by pressing the reset button with 4-6 N force (avoid excessive strength)
  • Ensure a minimum distance of 20.4mm between reset button and close cover for normal functionality

Auto Reset Type: Utilizes bimetallic strip temperature sensing components. When temperature reaches the action range, the mechanism snaps quickly and the movable disc disconnects. When temperature decreases to the fixed point, the contact point automatically resets and resumes operation without manual intervention.
