Fast 80FE fuse – circuit and device protection

This quick-blow fuse with a rated current of 80A, designed for use in AC and DC circuits, provides effective protection against short circuits and overloads. The construction compliant with BS88 standard guarantees reliability and safe operation in demanding applications. It is a key protective element in electrical installations, especially where a quick response to sudden current changes is required.

Characteristics and application

The 80FE fuse-link is characterized by a high short-circuit breaking capacity – up to 200 kA, making it an ideal choice for protecting semiconductor elements and circuits powering motors and converters. The aR usage category (semiconductor protection) indicates its specialization in protecting sensitive electronic components. Therefore, this fuse finds application in a wide range of devices and installations, such as:

• Switching power supplies
• DC drives
• Power converters
• Semiconductor circuits
• Uninterruptible power supply systems (UPS)

Construction and characteristic features

The 80FE fuse is distinguished by its compact design (19 x 77 mm) and solid construction. Mounting is done using M6 threads, which ensures a stable connection in the circuit. The lack of a blown indicator does not affect its functionality – damage to the fuse is easily identifiable visually by the break in the fusible element. It is worth noting the low power losses (20W at rated current), which translates into energy efficiency of the system. Compliance with IEC 60269 and BS88 standards confirms its quality and safety of use. The rated AC voltage is 690V, and DC – 500V, which allows for wide application in various electrical installations.
