Snap action thermal protector , automatic reset type with UL,VDE, CB, CCC , Rohs compliant

Work principle:

18AM-C thermal protector is a temperature automatic response devide and is connected in series to the winding of motor. 

 Normal closed type:  cutoff at temperature rises.  

Normal open type: contacts closed (ON) at temperature rises

Application:

18AMA series thermal protectors are devices for protecting against overload and over temperature. They are usually used for AC 220v /50Hz one phase motors to protect motor from over temperature caused by unusual state such as overload, blocked up. They are also used for protecting against over temperature & temperature control in lighting appliance, heater, fluorescent ballast, IC etc.
