Generic KSD301 135°C NC Thermostat Switch - Bakelite Housing, 250V 10A
The Generic KSD301 is a normally closed (NC) snap-action thermostat switch rated for 250V AC/DC and 10A, featuring a fixed 135°C (275°F) activation temperature. Its bakelite housing provides electrical insulation and thermal stability for integration into heating control circuits, appliance safety cut-offs, and industrial temperature protection systems.
Features
- Fixed 135°C (275°F) normally closed (NC) snap-action bimetallic thermostat
- Rated for 250V AC/DC and 10A switching capacity
- Bakelite housing for high electrical insulation and thermal resistance
- Compact and robust design for appliance safety and industrial control
- Simple two-wire installation for series connection in heating circuits

The KSD301 is a bimetallic disc-type thermostat that operates on a snap-action mechanism. When the ambient temperature reaches its calibrated set point of 135°C, the bimetallic disc deforms, causing the normally closed (NC) contacts to snap open, breaking the circuit. This provides a reliable, non-resettable (unless manually cooled) over-temperature cut-off function.
Encased in a durable bakelite shell, the switch offers excellent dielectric strength and resistance to tracking, making it suitable for direct integration into mains-powered heating elements, motors, transformers, and other equipment requiring thermal protection. Its simple two-terminal design allows for straightforward series wiring within the load circuit.
