Generic KSD301 120°C NC Thermostat Switch - Bakelite Housing, 250V 10A
The KSD301 is a normally closed (NC) bimetallic snap-action thermostat switch rated for 250V AC and 10A, designed to open its contacts at a fixed 120°C temperature. Its Bakelite housing provides electrical insulation and thermal stability for integration into appliances, heaters, and industrial control panels.
Features
- Fixed 120°C (±5°C typical) snap-action bimetallic disc switch
- Normally Closed (NC) contact configuration opens on temperature rise
- Rated for 250V AC / 10A resistive loads for direct power control
- Bakelite (phenolic) housing for electrical insulation and heat resistance
- Compact, screw-terminal design for easy panel or surface mounting

The KSD301 is a fixed-temperature, thermally actuated switch utilizing a bimetallic disc mechanism. When the ambient temperature reaches its calibrated set point of 120°C, the disc snaps to physically open the normally closed (NC) electrical contacts, breaking the circuit. This provides a reliable, non-resettable over-temperature cutoff without requiring external power.
Constructed with a Bakelite body, the switch offers excellent electrical insulation and resistance to thermal deformation. Its robust design is suited for direct integration into heating elements, motors, transformers, and other equipment requiring over-temperature protection or simple on/off thermal control within industrial, commercial, and appliance applications.
