Why Choose the Mersen R095994 Semiconductor Miniature Fuse?
The Mersen R095994, catalogue reference MI5SA40V0.2, is a compact semiconductor miniature fuse designed to protect sensitive electronic components against damaging overcurrents and short circuits. Part of Mersen's 5 × 20 mm SA fuse range, it combines precise low-current protection with a compact cartridge format suitable for industrial control and electronic equipment.
Its SA medium time-lag operating characteristic allows the fuse to tolerate brief current surges while still responding effectively to sustained overloads and electrical faults. This helps reduce unnecessary fuse operation in circuits containing capacitors, transformers, power supplies and other components that can produce temporary inrush currents during start-up.
With a rated current of 0.2 A and a rated voltage of 400 V AC, the R095994 provides dependable protection for sensitive low-current circuits. Its standard 5 × 20 mm cylindrical body is designed for clip mounting in a compatible fuse holder, allowing convenient installation, inspection and replacement.
