DZ47X AC and DC universal circuit breakers can be used in circuits with DC 12-400V or AC 90V-400V, and Miniature Circuit Breaker with rated currents ranging from 15A to 120A. B-curve (3-5ln) tripping design is adopted. The Miniature Circuit Breaker can be used in Home lighting, circuit on-off or application of DC circuit photovoltaic panels, UPS, batteries, inverters and other products for circuit overload protection or circuit isolation use.
It is not recommended to be used in high-power AC motor starting or high-power DC motor starting equipment, and it is easy to trip.
This Miniature Circuit Breaker meets the requirements of standards such as IEC60947-2
