Specifications

1. Scope of application

The design of CNSX series of MCCB reflects the latest current limiting principle and manufacturing technology, characterized by compact structures, full modularization, high breaking and zero arcover. Its rated insulation voltage is 750V, suitable for the circuit with AC 50/60Hz, rated operational voltage is 690V and below, and rated working current up to 630A, which will be used for generating infrequent conversion and infrequent startup of the motor. MCCB is equipped with overload, short circuit and under voltage protection devices, so as to protect the circuit and power supply equipment from damage.
