HC02-B Bimetal Motor Overload Protector 30A Thermal Cutout Switch
Product Overview
The HCET HC02 bimetal motor protector offers precise thermal overload protection (60°C-180°C ±8°C) for automotive and industrial equipment. Engineered with aerospace-grade bimetal technology, it automatically cuts off power within 4-10 seconds when detecting overheating or overload currents up to 30A.
This RoHS-certified protector ensures reliable operation in harsh environments (-40°C to +200°C) for wiper motors, sliding door actuators, sunroof mechanisms, and power tools. Customizable trip current settings and different terminal versions available.
