The HCET KSD9700/TB05 is an engineered-grade bimetal thermal cutoff switch, designed to deliver fail-safe circuit protection in industrial heating systems, motors, battery packs, and appliances. Featuring high-sensitivity snap-action bimetal disc technology, it provides instantaneous temperature-triggered cutoff (35°C-160°C, ±3°C/±5°C accuracy) to prevent overheating damage, electrical fires, and equipment failure.

• 10A continuous load capacity (resistive) - superior to standard 6A thermal switches
• Silver-nickel alloy contacts resist arcing & welding in high-cycle heating applications
• Instantaneous snap-action ensures fast circuit interruption at critical temperatures

• Automotive-grade bimetal disc with <1% failure rate
• Waterproof option for humid, dusty, or washdown environments
• Vibration-resistant design for HVAC compressors, industrial motors, and power tools

• UL, CE, RoHS certified - meets US, EU, and international safety standards

• Adjustable temperature settings (35°C-160°C)
• SPDT (Single Pole Double Throw) configuration for automatic or manual reset
• Compact size fits space-constrained heater controls

• Electric Water Heaters & Boilers - Prevents dry-fire damage
• Industrial Heating Elements - Ovens, furnaces, plastic molding machines
• Battery Pack Safety - Thermal cutoff for Li-ion & lead-acid batteries
• HVAC Systems - Protects compressors from locked-rotor overheating
• Home Appliances - Coffee makers, rice cookers, space heaters
