HCET in STOCK TB02 TB05 KSD9700 Plastic case Normally Open 105℃ Thermal Protector Bimetal Thermal Cutoff Switch

The HCET KSD9700/TB05 Bimetal Thermal Switch is a precision-engineered temperature and current-sensitive protector designed for reliable overload protection in demanding applications. Featuring a compact plastic housing and a snap-action bimetal disc, this thermal cutoff switch operates at a calibrated temperature of 105℃ (±3℃ tolerance) to safeguard motors, transformers, HVAC systems, and household appliances from overheating.

With a high-current capacity of 8A 125V AC and 6A 250V AC, it ensures robust performance in industrial equipment, lighting circuits, and fractional horsepower motors. The normally open (NO) design activates instantly upon reaching the preset temperature, interrupting power to prevent damage. UL, RoHS compliance guarantees global safety standards, while its resistance to vibration and humidity makes it ideal for automotive, commercial, and residential use.
