Product Description
HCET Bimetallic Thermal Overload Protector 10A-40A 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.
