HCET 5AP Bimetal Motor Overload Protector Resettable Thermal Circuit Breaker for Automotive & Electric Motors 12V/24V Systems

The HCET 5AP series is an advanced bimetal motor protection device engineered for automotive and industrial applications. Combining current sensitivity with ambient temperature detection, this self-resetting thermal protector ensures reliable overload protection for DC motors in demanding environments.

Featuring a precision-calibrated bimetal strip (50°C–180°C ±5℃ tolerance), it delivers rapid trip response (4–10 seconds) to prevent motor burnout during voltage spikes or overheating. With customizable terminals and 30,000+ operation cycles, the 5AP series is ideal for automotive subsystems like power windows, wipers, sunroofs, and door locks, while maintaining compatibility with industrial machinery and HVAC systems.
