NS1600 3P
Description:
The design of NSX series molded case circuit breakers reflects the latest current limiting principle and manufacturing technology. it has the characteristics of compact structure, full modularization, high breaking and zero flying arc. its rated insulation voltage is 750v, suitable for AC 50Hz, rated working voltage 690v, rated working current to 1250A circuit for infrequent conversion and motor infrequent start. The circuit breaker has overload, short circuit and undervoltage protection devices, which can protect the line and power equipment from damage. The circuit breaker complies with ICE60947-1 and 1CE60947-2 implementation standards.
