KSD302 Ceramic Normally Closed NC Temperature Control Switch Thermostat 130°C - 250V 10A
The KSD302 is a ceramic-housed, normally closed (NC) thermal switch designed for precise temperature control at 130°C in electrical circuits up to 250V AC/DC and 10A. It provides reliable, snap-action protection for heating elements, appliances, and power equipment.
Features
- Normally Closed (NC) snap-action switch opens at 130°C setpoint
- Rated for 250V AC/DC and 10A switching capacity
- Robust ceramic housing for electrical insulation and thermal stability
- Compact and durable design for direct PCB or chassis mounting
- Ideal for over-temperature protection and thermal cutoff applications

The KSD302 is a bimetallic, snap-action thermal switch enclosed in a high-grade ceramic body. The ceramic material provides excellent electrical insulation, high dielectric strength, and stable thermal performance, ensuring the switch operates reliably at its calibrated trip point without drift. The normally closed contacts open automatically when the sensing surface reaches the factory-set temperature of 130°C, breaking the circuit to prevent overheating.
This device functions as a one-shot thermal protector or a resettable thermostat, depending on the circuit design. After tripping, the contacts will close again once the temperature cools below the reset point, allowing for automatic or manual system recovery. Its simple two-terminal design makes it easy to integrate into AC or DC power lines for heaters, transformers, motors, and other equipment requiring overtemperature protection.
