1. Scope ofapplication
The designof CNSX series of MCCB reflects the latest current limitingprinciple and manufacturing technology, characterized by compactstructures, full modularization, high breaking and zero arcover.Its rated insulation voltage is 750V, suitable for the circuit withAC 50/60Hz, rated operational voltage is 690V and below, and ratedworking current up to 630A, which will be used for generatinginfrequent conversion and infrequent startup of the motor. MCCB isequipped with overload, short circuit and under voltage protectiondevices, so as to protect the circuit and power supply equipmentfrom damage.
