HCET-B Power-off Thermal Cutoff Switch 35A Overload Protector for Motors & Appliances Dual Current with Temperature Protection
The HCET-B Thermal Cutoff Switch is a self-resetting safety device designed to protect motors and electrical equipment from damage caused by overcurrent and overheating. Combining precise temperature sensitivity (50-180°C customizable) with adjustable current trip settings (1-35A), this dual-protection switch automatically interrupts power within 3-8 seconds of detecting dangerous conditions, then resets when temperatures normalize. Certified to RoHS standards, its compact insulated housing ensures reliable operation in demanding environments including power tools, HVAC systems, and industrial machinery.
Product feature:
