The HCET-B Thermal Cutout Switch is a precision-engineered bimetal protector designed to safeguard motors and electrical systems from overheating and current overload. Combining temperature sensitivity (50℃-180℃ customizable) and adjustable trip current (1-35A), this self-holding thermal cutoff switch ensures reliable power interruption within 3-8 seconds, preventing irreversible damage to equipment like dust collectors, industrial motors, and HVAC systems.
Featuring a manual reset function and insulated housing, it complies with EU RoHS standards for safety and environmental sustainability. Ideal for global markets requiring robust thermal management, the HCET-B is trusted in applications ranging from power tools to home appliances, offering precise protection with compact, easy-to-install design.

Product feature:

 Dual Protection Mechanism
 	Senses both temperature rise and current overload (1-35A adjustable), providing comprehensive defense against motor burnout.  
Precision Trip Timing
 	Triggers power cutoff in 3-8 seconds (customizable) to prevent overheating while minimizing downtime.  
Self-Resetting Function
 	Automatically restores operation after cooling or manually reset post-fault for maintenance flexibility.  
Wide Temperature Range
 	Operates at 50℃-180℃ (±5℃/±8℃ tolerance) with customizable trip points for diverse thermal environments.  
RoHS-Compliant & Durable
 	Insulated PBT shell ensures safety in high-voltage scenarios (up to 250V AC/30V DC).  
Multi-Industry Application
 	Optimized for dust collectors, lawn mowers, washing machines, HVAC systems, and industrial power tools.
