HCET 3MP Bimetal Thermal Protector Switch Self-Hold Overload Protection 6AP/5AP Compatible for Car DC Motor
The HCET 3MP series thermal protectors are precision-engineered bimetal disc switches designed for critical motor protection across industrial and consumer applications. As a high-performance alternative to Sensata Klixion, our self-hold mechanism ensures reliable circuit interruption (4-10s response time) during overloads, short circuits, or motor lock conditions, with manual reset capability after power cutoff. With customizable trip currents up to 45A and temperature ranges from 30℃-180℃ (±5℃ precision), these RoHS-compliant protectors are ideal for demanding environments requiring UL-equivalent safety standards.
