NB1Z-63 AC and DC small circuit breaker

Function and use

NB1Z-63 AC and DC small circuit breaker is suitable for overload and short-circuit protection in lines with AC 50Hz, rated voltage 230/400V, and rated current up to 63A, or DC voltage 220V, rated DC current up to 63A. It can be used for infrequent switching of lines under normal circumstances, and can also be used as an isolation switch for disconnecting lines for line and equipment maintenance. Circuit breakers are suitable for various places such as industrial, commercial, high-rise and residential buildings. Comply with standards: GB/T 10963.2, IEC 60898-2, and obtain CCC, CE, SEMKO certification.
