HCET 8AM Series 15-60A Motor Overload Thermal Protector Dual Temperature Current Sensitive Cutoff Switch for Large Wiper Motor
The HCET HC18/8AM series is a professional-grade thermal protection device engineered for precision motor overload protection in demanding environments. Combining temperature and current dual-sensing technology, this UL/CE certified protector automatically disconnects power within 4-10 seconds when detecting abnormal conditions (overheating up to 180℃ ±5℃ or current overloads 15-60A). Its military-grade construction ensures reliable performance in automotive systems (EV motors, fuel pumps), marine equipment (bilge pumps, trolling motors), and industrial machinery (compressors, HVAC systems). Customizable with brass/nickel terminals and 150mm-500mm silicone/PVC wires to meet specific OEM requirements.
