The NXB-63S/C20-4P-4.5 circuit breaker offers safe and effective protection against overloads and short circuits in three-phase electrical systems. Due to the tripping curve C, it is suitable for loads with moderate inrush currents, such as motors, switchgear and machinery.
The C curve can tolerate short-duration overcurrents up to five to ten times the rated current and is widely used in domestic systems.
This 4-pole, 50 A device operates with a voltage of 400 V and a frequency of 50/60 Hz, ensuring reliability in industrial and tertiary settings. With 4 DIN modules and IP20 degree of protection, it easily integrates into any standard electrical panel.
The breaking capacity of 4.5 kA, limitation class 3 and impulse voltage of 4 kV make this circuit breaker suitable for protection even in the presence of voltage spikes. Low power dissipation (4.5 W) enables efficient and safe operation.
It can be accessorized with:
AX-X1 auxiliary contacts
AL-X1 alarm contacts
SHT-X1 trip coils
Minimum voltage coils UVT-X1
