Product Introduction:

BW-A1D Metal Thermal Overload Protector is consist of high sensitive bimetal , active contact-head , passive contact plate , outer case , thermal resistant lead etc .

When operating , bimetal disc is in free state , active contact head and passive contact plate are closed and circuit is on . When working electric machine is in operation and produce heat caused by some trouble and temperature raise to the rated action temp. . The bimetal produce inner stress and act quickly to push the movable contact head and make the contact point off . In the end ,power supply is cut down. Overheat protection is completed .

When the machine attached temperature decrease to rated reset temperature , bimetal restore to initial state that the movable contact head close , the machine continue working .

Competitive Advantage :

Small resistance , quick sensitive to temperature , action quickly , reliable , small in size

Attention :

The thermal protector hereof applies to electrical and mechanical  , ballast , and other types of electrical , electronic equipment and household appliances and parts , overheat protection , to prevent dangerous overheat components under fault conditions , in order to avoid accidents .

Sealed structure  , which ensure it to work consistently under severe conditions . When the outer case is metal  , when circuit is on ,this metal case is electrified body , when installation , please apply the insulated jacket from our factory .

When you select the specific thermal protector , remember to choose the one which meets the specification which suits the working voltage and circuit .

When installation , pay attention that lead connection in good condition  prevent it from virtual connection which will cause extra heat to influene the normal working of protector .
