Product Details
HCET Series Customizable Bimetallic Thermal Overload Protector
10-40A Motor Thermal Protector for Motors/Compressors
HCET series customizable overload protector utilizes a
precision-calibrated bimetallic strip that bends under abnormal
current-induced heat. When temperatures exceed the preset threshold
(e.g., motor overload or compressor failure), the strip triggers an
instant mechanical cutoff (4-10s response) to prevent equipment
damage. After cooling, the device auto-resets without manual
intervention, ensuring continuous protection.
Product feature:
- Industrial Machinery:
Safeguards motors (0.5-30kW), CNC machines, and pumps from burnout.
HVAC Systems:
Protects compressors in commercial cooling units and heat pumps.
Renewable Energy:
Stabilizes solar inverters and EV charging stations under voltage
surges. - Harsh Environments:
Operates in -30°C to 200°C for oil rigs, chemical plants, and
marine equipment.
