The NXB-63S circuit breaker is designed for overcurrent, overload and short-circuit protection in terminal distribution circuits. Thanks to its tripping curve C, it can support temporary overcurrents up to 5-10 times the rated current, making it ideal for use in domestic, tertiary and light industrial applications.
The NXB-63S series offers high performance combined with a compact design. The 4-pole model allows complete protection even in three-phase systems. With an interrupting rating of 4.5 kA, it is suitable for standard electrical panels with reduced depth, maintaining high efficiency in civil and commercial use environments.
The device is compatible with:
AX-X1 series auxiliary contacts
AL-X1 series alarm contacts
SHT-X1 series trip coils
UVT-X1 minimum voltage coils
Not compatible with differential modules
