HCET KSD301 is a high-precision automatic reset bimetal thermostat designed for precise temperature control in critical applications. Utilizing bimetal disc technology, this normally closed (NC) switch activates when temperatures exceed preset thresholds (adjustable range: -10°C~280°C), instantly breaking the circuit to protect equipment from overheating.

Its flange mount design ensures durability in harsh environments, while certifications including TUV and RoHS guarantee compliance with global safety and environmental standards. Widely used in HVAC systems, commercial appliances, industrial motors, and automotive electronics, the KSD301 offers reliable thermal protection with a lifespan of over 100,000 cycles.

• Precision Temperature Control: Bimetal disc technology ensures ±3°C accuracy with customizable range (-10°C~280°C)
