Selective Type Automatic Fuses - SMCB

Selective type automatic fuses are circuit breakers designed for overload and short circuit protection in electrical installations. These fuses increase safety in complex power systems by providing exceptional selectivity for both downstream and upstream protection devices with their unique current limiting selectivity.
 These types of fuses are ideal for critical areas requiring energy distribution. They offer maximum service continuity in places where constant energy flow is critical, such as data centers, hospitals and office buildings. Designed for overvoltage category IV, these devices can be preset as the main protection and isolation device in main distribution panels or metering panels. These selective type MCBs from ABB can operate completely independently, without being connected to an external power supply or neutral conductor, making them more flexible and reliable in power systems. These features make selective type MCBs unique to meet the demanding needs of modern energy systems.
