Protection of DC circuits against short-circuit and overload currents,switching and isolation.
BX8Z-63 DC mini circuit breakers are suitable for DC power distribution systems and electrical equipment, including photovoltaic, energystorage and other DC applications.
Technical data of the DC system at the point considered: rated voltage,rated current, number of poles and prospective short-circuit current.The prospective short-circuit current at the circuit-breaker installation point must not exceed the breaking capacity of the device.
The appropriate tripping curve should be selected according to the load characteristics:
C curve (8.5In+/-20%)
Suitable for general circuits and loads with moderate inrush current.
D curve (10In+/-20%)
Suitable for circuits supplying loads with high inrush current.
Both polarized and non-polarized versions are available according to different DC system and wiring requirements.
