Why Choose the Mersen R087024 Semiconductor Miniature Fuse?
The Mersen R087024, catalogue reference MI5SA25V5, is a compact semiconductor miniature fuse designed to protect sensitive electronic components and control equipment against damaging overcurrents. Part of Mersen's 5 × 20 mm SA/SB miniature fuse range, it provides dependable circuit protection for industrial electronics, automation equipment and electrical control apparatus.
Its SA medium time-lag operating characteristic allows the fuse to withstand short-duration current surges while still responding to sustained overloads and short-circuit conditions. This helps prevent unnecessary fuse operation in circuits containing capacitors, transformers, power supplies and other components that may produce temporary inrush currents when energised.
With a rated current of 5 A and a rated voltage of 250 V AC, the R087024 is suitable for a broad range of electronic and industrial control circuits. Its standard 5 × 20 mm cylindrical format is designed for clip mounting in a compatible fuse holder, allowing straightforward installation, inspection and replacement.

Its compact cartridge construction makes it suitable for control panels, electronic power supplies, instrumentation and automation equipment where installation space is limited. When fitted in a correctly rated fuse holder, the R087024 provides serviceable circuit protection that can be replaced quickly during maintenance.
Typical Applications
- Industrial control and automation equipment.
- Semiconductor and electronic circuits.
- Electronic power supplies.
- Instrumentation and measurement systems.
- Control apparatus and relay circuits.
- Circuits with temporary start-up or inrush currents.
