Protection of DC circuits against short-circuit and overload currents,switching and isolation.
EBS7Z-63 DC mini circuit breakers are suitable for DC power distribution systems and electrical equipment, including photovoltaic, energy storage 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 installationpoint must not exceed the breaking capacity of the device.
The appropriate tripping curve should be selected according to the load characteristics:
B curve (4In-7In)
Suitable for circuits with relatively low inrush current.
C curve (6In-10In)
Suitable for general circuits and loads with moderate inrush current.
D curve (10In-14In)
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.
