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.

• Dual-Sensor Protection
  • Simultaneously monitors temperature (±5°C accuracy) and current overloads
  • Prevents motor burnout in critical applications (e.g., lawn mowers, vacuum cleaners)
• Adjustable Trip Settings
  • Customizable current protection range 1-35A with 3-8s response time
  • Temperature activation threshold configurable from 50°C to 180°C
• Manual Reset Function
  • Requires intentional reactivation after tripping for added safety
  • Prevents accidental restarts in industrial equipment
• Robust Construction
  • PBT housing withstands 250V AC/30V DC
  • Compact design (20.2mm dimensions) for space-constrained installations
