The NXB-63S circuit breaker is designed to protect terminal electrical circuits against overcurrents, such as overloads and short circuits. It is part of the NXB-63S series, known for its reliability, efficiency and ease of installation, ideal for civil, domestic and small commercial electrical installations.
Curve C allows the breaker to tolerate temporary overcurrents up to 5-10 times the rated current, making it perfect for lines that supply devices with peak loads, such as appliances, outlets and lighting.
This model is compatible with a range of optional accessories for circuit monitoring and management:
AX-X1 auxiliary contact
AL-X1 alarm contact
SHT-X1 trip coil
Minimum voltage coil UVT-X1
Note: not compatible with differential modules
