Why Choose the Mersen R084402 Semiconductor Miniature Fuse?
The Mersen R084402, catalogue reference MI6SA25V0.25, is a compact semiconductor miniature fuse designed to provide reliable overcurrent protection for sensitive electronic components and industrial control apparatus. Part of Mersen's 6.3 × 32 mm SA fuse range, it combines dependable circuit protection with a compact cartridge format suitable for modern electrical 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 short-circuit conditions. This helps prevent unnecessary fuse operation in circuits containing transformers, capacitors, power supplies and other components that can produce temporary inrush currents during start-up.
With a rated current of 0.25 A and a rated voltage of 250 V AC, the R084402 is suitable for protecting sensitive low-current circuits. Its standard 6.3 × 32 mm cylindrical body is designed for clip mounting in a compatible fuse holder, allowing convenient installation, inspection and replacement.
