HCET HC18/8AM series advanced thermal overload protectors are engineered to provide dual-sensitive protection for motors and transformers against both overheating and excessive current. With a robust 15-60A fault tolerance and precision temperature calibration (80-180°C ±5/8°C), this thermal cutoff switch ensures rapid response within 4-10 seconds.  

Product feature:

Dual Protection Technology
Temperature & current-sensitive design prevents motor burnout from both overheating (up to 180°C) and overloads (60A max).
High-Current Resilience
Handles surge currents up to 60A at 250VAC, validated through 10,000-cycle endurance testing.
Precision Response
Factory-calibrated thermal discs with ±5°C tolerance ensure trip accuracy (±8% current variance) for critical applications.
Multi-Voltage Compatibility
Operates seamlessly across 12-24VDC automotive systems and 125-250VAC industrial equipment.
Fast-Acting Protection
4-10 second trip time prevents winding damage in motors and transformers.
