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.
