The HCET HC02 is a precision-engineered bimetallic motor overload protector designed to safeguard motors and transformers from overheating, overloads, and short circuits. Engineered as a direct replacement for Otter series protectors, this compact, high-temperature plastic switch combines dual sensitivity to temperature and current, ensuring reliable protection for automotive systems (e.g., window motors, wipers, sunroofs), HVAC equipment, industrial machinery, and home appliances.

With customizable trip currents (1-30A) and temperature thresholds (60-180°C ±8°C), the HC02 delivers precise tripping in 4-10 seconds, preventing motor burnout while meeting strict RoHS compliance for global markets.
