Product Description

>> Application  


Moulded case circuit breakers are low-voltage circuit breakers. They meet the installation needs of small users all the way to large industrial substations and power distribution systems. They are commonly applied in steel mills, oil platforms, hospitals, railway systems, airports, computing centers, office buildings, convention centers, theaters, skyscrapers, and other large scale structures.

 

>>  Working principle  


The main contact of the molded case circuit breaker is manual manipulation or electric closing. After the main contact is closed, the free release mechanism locks the main contact into the closing position. The over current trip coil and the thermal trip element are connected in series with the main circuit. The under voltage release coil and the power supply are connected in parallel.
