Acti9 SBI Fuse Base – Reliable Installation Protection

The Acti9 SBI fuse base is an element of the electrical protection system, designed to work with 22x58 mm fuse links. It provides effective protection against overloads and short circuits in electrical circuits, finding application in both residential and industrial buildings. It is a solid solution for installers and users who value safety and reliability.

Installation and Functionality

The device is designed for mounting on a 35 mm DIN rail, which simplifies and speeds up installation in electrical switchboards. A width of 6 modules (105 mm) allows for efficient use of space in distribution cabinets. The three-pole design (3P) allows for the protection of the entire circuit, and the optical trip indicator allows for quick identification of a blown fuse. The rated voltage of up to 690 V AC makes it a universal solution for many applications.

Application and Compatibility

The Acti9 SBI fuse base works with fuses of gG characteristics (protection against overload and short circuit) and aM (motor protection against short circuits). This allows it to be adapted to the specific needs of a given installation. Screw terminals allow the connection of copper conductors with a cross-section from 2.5 mm² to 25 mm², both rigid and flexible. It meets the requirements of IEC EN 60947-3 standard, which guarantees a high level of safety and compliance with applicable regulations. The degree of protection IP20 provides basic protection against accidental contact.
