EAW SO Self-Hold Thermal Cut-outs

These snap-action devices, with Quick Make/Quick Break action, automatically reset at preset temperature. An electrically isolated bimetal disc is used to either open or close the circuit current.

In a fault condition, the control opens activating an internal heat source which holds the device in an open condition until the power is removed and the unit is allowed to cool.  The control then resets allowing continued operation.
