BW-EOM Epoxy resin Thermal protector

Main parts

1) Shell  2) Base  3) Bimetal disc  4) Movable contact

5) Temperature calibration plate  6) Static contacts

 

Construction

The movable contact are welded to the bimetal sheet and then wel-ded to the iron bracket. The stationary silver contact and base are molded into a whole, after the current passes through the temper-ature calibration plate and the bimetal disc, it forms a loop from the moving contact to the static contact.


Function

Under normal conditions,  the moving contact is in close contact with the stationary silver contact under the pre-pressure of the bimetal disc;  When the rated operating temperature is reached, the bimetal disc is deformed by heat and snap rapidly,  cut off the circuit. After that, the device begins to cool down. When it reaches the defined reset temperature, the bimetal disc and the spring disc snaps back into its start position, the contacts will close again, and the device starts working again.
