The HCET-T Series Intelligent Thermal Motor Protector delivers precision protection for automotive and industrial applications. Engineered with high-temperature resistant polymer housing, this overload protector provides dual safeguards against both thermal runaway (60°C-180°C adjustable) and current overloads (1-80A DC/30-250V AC). 
Ideal for critical vehicle systems including oil pump motors, wiper mechanisms, and tipper truck tarpaulin drives, its fast-acting bimetal trip mechanism (4-10s response time) prevents motor burnout in overload/stall conditions. With RoHS-compliant materials, this compact protector (dimensions customizable) ensures reliable operation in harsh automotive environments.
