Product Description
1. 15A High-Current Capacity
Rated for 15 amperes continuous current, suitable for larger compressor motors up to 1.5 HP at 250V AC or 0.75 HP at 125V AC.
2. Bimetal Disc Thermal Sensing
Precision-calibrated bimetal disc responds accurately to both motor winding temperature and ambient heat, tripping within ±5°C of rated temperature.
3. Automatic Reset Function
Resets automatically when motor temperature drops to safe range (70°C–100°C), eliminating the need for manual intervention while protecting against repeated overload cycles.

fAQ
Q: Do you provide sample?
A: Yes, samples fee and freight fee will be charged by your side.
Q: Where is the termico protector mounted on the compressor?
A: It is typically mounted directly against the motor winding end, often under a metal retaining clip, or embedded in the motor housing for accurate temperature sensing.
Q: How can I test if my thermal protector has failed?
A: Allow the compressor to cool completely for 30–60 minutes. If the motor still does not start, test continuity across the protector terminals with a multimeter. An open circuit indicates failure.
