Fuse combination unit, Acti9 SBI, 3P, 50A, cartridge size 14 x 51 mm, SBI-50-3 A9GSB350

Safety and reliability in your installation – Acti9 SBI base

This three-pole Acti9 SBI fuse disconnector is a key element ensuring protection against overloads and short circuits in electrical installations. It will work in residential and commercial buildings, as well as in demanding industrial environments and OEM applications. The design allows for mounting on a DIN rail, which facilitates integration with existing systems and ensures the modularity of the installation.

Versatility and compatibility

The SBI-50-3 fuse base is designed to work with 14 x 51 mm fuse links, supporting gG (overload and short-circuit protection) and aM (motor short-circuit protection) curves. This allows it to be adapted to different types of loads and installation needs. The rated switching voltage of up to 690 VAC guarantees a wide range of applications.

Mounting and connection

Mounting on a DIN rail is quick and intuitive. Connection of copper conductors (rigid or flexible) is done using screw terminals, accepting cross-sections from 2.5 mm² to 25 mm². The optical tripping indicator allows for quick identification of a blown fuse, which speeds up diagnostics and minimizes downtime. The device width of 4.5 modules allows for efficient use of space in the switchgear cabinet.
