KSD301, 100°C Bimetal Thermostat Switch, Surface Mount Package

The KSD301 100°C Thermostat Switch is a temperature-controlled automatic switch designed to protect appliances and electrical equipment from overheating. When the surface temperature reaches 100°C, the bimetallic disc inside the switch activates and opens the circuit, stopping the flow of current. Once the temperature drops, the switch resets automatically. Ideal for thermal protection in heaters, dryers, electric kettles, and power supplies, the KSD301 provides a reliable, mechanical thermal cut-off solution with long service life and high current handling.

Key Features:

• Fixed Temperature Rating (100°C) – Automatically activates at 100°C to control overheating or initiate thermal cut-off.
• SPST Normally Closed Contact – Opens the circuit at the preset temperature and resets automatically when cooled.
• High Current Capacity – Rated for 10A at 250V AC, suitable for a wide range of electrical appliances.
• Fast Response Time – Uses a bimetal disc for rapid thermal sensing and switching.
• Easy Installation – Surface-mount bracket with mounting holes allows secure attachment to heating elements or surfaces.
• Compact and Reliable Design – Small form factor ensures easy integration in space-constrained assemblies.
