Why Choose the Mersen M093575 High-Speed Cylindrical Fuse?

The Mersen M093575, also identified as FR20GB15C3,15P, is a high-performance 3.15 A high-speed cylindrical fuse-link developed for the protection of sensitive power electronic equipment and industrial control circuits. Manufactured as part of Mersen's advanced semiconductor protection range, this fuse delivers rapid fault interruption to help minimise damage caused by short circuits and excessive currents.

Its 20 × 127 mm cylindrical format provides a compact and dependable solution for installations where fast-acting protection is required. The fuse is designed to respond significantly faster than conventional general-purpose fuse-links, helping protect semiconductor devices and associated components with low thermal withstand capabilities.

With a rated current of 3.15 A and a maximum AC operating voltage of 1500 V, the M093575 is suitable for high-voltage industrial applications, including control power supplies, monitoring equipment, auxiliary circuits and specialised power conversion systems.
