Product Description

1.Application:
NSX series of moulded case circuit breaker is new type product developed and manufacturered by adopting international advanced technology.It is a sipplied with rated insulation voltage 800V and used for circuit of AC 50HZ,rated operating voltage AC 400V or below rated operation current up to 800A for infrequent changing over and starting of the motors. Equipped with the protection devices for over-current,short circuit and under voltage,the products is capable of preventing damage of circuits and supplying units.The product confirms to IEC60947-2 standard.
2.Specification:
NSX series moulded case circuit breaker/MCCB is one of the most advanced type breakers in the world, which adopt international advanced design and manufacture fechnology. They are suitable for short circuit and overload protection for circuit of AC 690V 50/60Hz, rated current from 12.5A to 630A. It takes protect effect when mouse cage motors non-frequent start, breaking off working and protecting overload, short circuit and lacking voltage.
