KSD301 Temperature Protector H31 Bimetallic Thermostat KSD302
Thermostat KSD301 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, which in turn opens or
closes the electrical circuit. Key features include fixed working
temperatures, reliable snap action, minimal flashover, extended
service life, 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. The contact point cannot reset until the
reset button is pressed manually, even when temperature declines.
(Note: This type can reset when temperature declines 20°C after
snap action by pressing the reset button with 4-6 N force. Ensure
at least 20.4mm clearance between reset button and cover.)
- 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, the contact point automatically resets and resumes
operation.
