Fuse base STI-8.5x31.5-3N 3+N-pole A9N15657

Robust installation protection with Schneider Electric STI-8.5x31.5-3N fuse base

This three-pole (3P+N) fuse base is a reliable element of any electrical installation, both in public buildings and in industry. It provides effective protection against overloads and short circuits, and its DIN rail mounting makes integration with the existing system simple and quick. The design allows for easy replacement of fuses without disconnecting the circuit – which translates to minimal downtime.

Functionality and application

The STI base is compatible with 8.5 x 31.5 mm fuses, providing flexibility in choosing the appropriate protection. The ability to use gG (general purpose) or aM (for motor loads) fuses allows you to adapt the protection to the specifics of a given circuit. The built-in optical trip indicator facilitates quick identification of a blown fuse – saving time during diagnostics and repairs. Additionally, the ability to lock with a padlock increases security and prevents unauthorized manipulation.

• Versatility: ideal for commercial and industrial applications.
• Easy installation: thanks to the standard DIN rail mounting.
• Trip indicator: quick identification of a blown fuse.
• Security: possibility of protection against unauthorized access with a padlock.
• Compliance with standards: the product meets stringent safety standards (IP20).

The Schneider Electric STI-8.5x31.5-3N fuse base is not only a protective element, but also an investment in the long-term and reliable operation of the electrical installation. Its solid construction and high quality workmanship guarantee trouble-free use for many years. The IP20 degree of protection provides protection against accidental contact and the ingress of solid objects larger than 12.5 mm – which is important in industrial and workshop environments.
