Functions and Uses
The DZ47-60M plastic-enclosed circuit breaker is suitable for AC 50Hz, rated voltage up to 400V, and rated current not exceeding 63A distribution lines; it can also be used in DC voltage single-pole not exceeding 110V, two-pole not exceeding 220V, and rated DC current not exceeding 63A distribution lines. The circuit breaker serves as a short-circuit protection device in the distribution line and can be used for infrequent switching in normal conditions.
