Function and Usage
The DZ47-60 miniature circuit breaker is mainly used in AC 50Hz circuits with a rated voltage up to 400V and a rated current up to 63A for overload and short-circuit protection. It can also be used to frequently switch electrical devices and lighting circuits under normal conditions, but it is not suitable for motor protection. It complies with the standards GB/T 10963.1 and IEC 60898-1, and has obtained the CCC certification.
