Self-Hold Snap Action Thermal Protectors

Portage Electric is offering a new addition to the Valstat Series™ of thermal controls.  The new series is self-hold thermal protectors designed as a cost effective solution for thermal protection of motor, transformer, lighting and appliance applications.  In a fault condition, the Model JSC opens the electrical circuit and an integrated heat source prevents the thermal protector from reclosing until the power source is removed and the unit is allowed to cool.  Ther thermal protector then resets allowing continued operation.  Self-hold devices allow for the functionality of automatic reset devices with additional safety enhancements.
