Fuse base STI-8.5x31.5-3 3-pole A9N15655

Fuse base for installation protection

Fuse base STI-8.5x31.5-3 is an element used for mounting cylindrical fuses with dimensions of 8.5 x 31.5 mm. Designed for mounting on a DIN rail, it provides effective protection of circuits against overload and short circuit. This is an ideal solution for both commercial buildings and industrial applications where high reliability and breaking capacity are required.

Construction and mounting

Made of high-quality materials, the fuse base is characterized by a solid construction and easy mounting on a standard DIN rail. It occupies 3 modules in width, which allows for efficient use of space in the distribution board. The enclosed construction increases safety, and the possibility of locking with a padlock provides additional protection against unauthorized access. An optical indicator of operation facilitates quick identification of a blown fuse.

Application and compatibility

This base is compatible with fuses of characteristic gG (general purpose) and aM (for motor protection). The rated current of up to 10A allows for the protection of various electrical circuits. The degree of protection IP20 provides protection against accidental contact, and IP40 when placed in a modular enclosure. It does not disconnect the N pole simultaneously, which should be taken into account when designing the installation. The device has 3 poles and is designed to operate at a rated voltage of 400V.
