HCET 5AP Series Bimetal Motor Overload Protector Thermal Cutoff Switch for Automotive/Tools/Pumps
The HCET 5AP series motor protection switches are precision-engineered bimetal thermal protectors designed for critical circuit protection in demanding industrial environments. Featuring dual-sensitivity (current + ambient temperature) technology, these devices deliver reliable overload protection for 12V/24V DC automotive systems and 120V/240V AC industrial motors. With 30,000+ mechanical cycles endurance rating, they prevent motor burnout in window lift mechanisms, HVAC compressors, power tools and water pump applications. The industrial-grade stainless steel bimetal strip ensures ±5℃ temperature accuracy with 4-10 second trip response. Customizable terminal configurationsand lead wire options (22-16 AWG silicon/PVC) enable seamless integration in OEM designs.
