MERSEN FUSE 400V SA 4 A 6.32 R098248

Why Choose the Mersen R098248 Semiconductor Miniature Fuse?

The Mersen R098248, catalogue reference MI6SA40V4, is a compact semiconductor miniature fuse designed to protect sensitive electronic components and industrial control apparatus against damaging overcurrents. Part of Mersen's 6.3 × 32 mm SA miniature fuse range, it provides dependable circuit protection for industrial electronics, automation systems and electrical control equipment.

Its SA medium time-lag operating characteristic allows the fuse to withstand brief current surges while still responding effectively to sustained overloads and short-circuit conditions. This helps prevent unnecessary fuse operation in circuits containing transformers, capacitors, power supplies and semiconductor components that can produce temporary inrush currents during energisation.

With a rated current of 4 A and a rated voltage of 400 V AC, the R098248 is suitable for demanding electronic and industrial control circuits. Its standard 6.3 × 32 mm cylindrical format is designed for clip mounting in a compatible fuse holder, allowing straightforward installation, inspection and replacement.
