HC01/6AP Bimetallic Motor Overload Protector 1-45A Thermal Cutoff Switch for Automotive/Industrial/Household Motors

The HCET HC01/6AP series of bimetal motor protectors are intelligent thermal protection solutions designed for harsh operating conditions. The devices provide dual protection for window motors, wiper systems, white goods motors and industrial drive equipment by synchronizing the monitoring of current overload (1-45A) and ambient temperature (30-180°C customizable) through bimetal composite sensing technology.

Its patented snap-action structure ensures precise cut-off of faulty circuits within 4-10 seconds, preventing overheating and damage to motor windings.
