Typical Applications
Operation Principle
The HCET bimetallic overload protector utilizes thermal deformation of precision-calibrated bimetallic elements to detect temperature changes. When abnormal current causes temperature to exceed preset thresholds, the bimetal bends to trigger mechanical linkage, cutting power within 4-10 seconds. Automatic reset occurs when temperatures normalize, requiring no manual intervention.
