Mersen S084403 medium time-lag semiconductor miniature fuse with a 0.5 A current rating, 250 V AC voltage rating and compact 6.3 x 32 mm clip-mounted cartridge design.
£2.84
The Mersen S084403 is a compact and dependable medium time-lag semiconductor miniature fuse designed to protect sensitive electronic components, semiconductor devices and industrial control apparatus against damaging overcurrents. Part of the Mersen MI6 SA 125V–250V series, it combines reliable fault protection with the ability to withstand brief current surges during normal equipment operation.
With a rated current of 0.5 A and a rated voltage of 250 V AC, the S084403 is suitable for low-current electronic and control circuits that may experience temporary inrush currents. Its medium time-lag SA characteristic helps reduce unnecessary fuse operation while maintaining effective protection against sustained overloads and short circuits.
The fuse features a compact 6.3 × 32 mm cartridge format and is designed for clip mounting in a compatible fuse holder. Its robust construction, very high breaking capacity and dependable operating characteristics make it suitable for industrial controls, instrumentation, power supplies and electronic assemblies.
Medium time-lag fuses are engineered to tolerate short-duration current increases caused by equipment start-up, capacitor charging and other normal operating conditions. This helps prevent nuisance operation while ensuring prolonged overloads and short circuits are safely interrupted.
The Mersen S084403 protects sensitive semiconductor devices and electronic control equipment while supporting reliable system operation. Its compact cartridge construction allows straightforward integration into equipment where installation space is limited and dependable circuit protection is essential.
