Today i am writing about the refrigerator overload protector testing using multi meter.

Thermal overload relay testing.

Thermal overload relay testing manufacturers factory suppliers from china our merchandise are widely recognized and trusted by users and can meet up with continuously changing economic and social needs. Literature technical tips faqs cep7 overload relay test procedures. A thermal overload relay works in the principle of electro thermal properties in a bimetallic strip. Overload relay working principle thermal overload relay thermal overload relay construction working and application.

In this post i will complete guide you about how to test a refrigerator thermal overload protector using a multimeter. Our normal production test procedure is not something that a customer could easily duplicate however a basic on site test can be run following the examples below. As you know that thermal overload protector is designed to protect the refrigerator compressor during over current flow. We need to setting the value of overload relay properly depend on our application and motor full load ampere if we setting low from fla it can cause motor trip c0ntinues and process not running smoothly.

Anything more specific would have to be furnished by the relay manufacturer as a model dependent time current characteristic curve or band as the case may be. Overload relay is the one of important device for motor control it can prevent our motor from overheat or winding burning due overload of ampere. How to set thermal overload relay. Say relay0 625 1 ampere range set at1 ampere.

Remove the screws that hold the panel in place to free it. The overload class 10 20 30 is supposed to be the time in seconds that the relay operates at 500 of rated. It is placed in the motor circuit in such a way that the current to the motor flows through its poles. The bimetallic strip gets heated up by the current directly or indirectly and when the current flow exceeds the set value it bends.

In case of thermal bymetalic relay. Locate the thermal overload switch behind the bottom toe or back panels of most residential clothes washers or dryers. What procedure can be used to test the phase loss or overload protection on a cep7 overload relay. Note that some appliance panels are held in place with small metal clips.

Dishwasher thermal overload switches can usually be found behind the bottom toe panel.
