Protection of DC circuits against short-circuit and overload currents,switching and isolation.EBS7Z-125H DC mini circuit breakers are suitable for higher-currentDC power distribution systems and electrical equipment, includingphotovoltaic, 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 installation
point 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-10ln)
Suitable for general circuits and loads with moderate inrush current.
D curve (10In-14In)
Suitable for circuits supplying loads with high inrush current.
EBS7Z-125H adopts a non-polarized design, allowing flexible wiring without polarity restrictions.
