Mersen S076836 FR20GB10C4P high-speed cylindrical fuse rated at 4 A and 1000 V AC, with gLB utilisation category and an integrated striker for semiconductor protection.
£40.94
The Mersen S076836, also identified as FR20GB10C4P, is a high-performance high-speed cylindrical fuse designed to protect sensitive semiconductor devices and power electronic equipment against damaging overcurrent and short-circuit conditions. Its rapid operating characteristics help limit the electrical energy passed into protected components during a fault.
Featuring a gLB utilisation category, the S076836 provides dependable protection for circuits containing power semiconductors. Its robust cylindrical construction supports reliable operation in demanding industrial environments, while the integrated striker enables visual or remote indication when the fuse has operated.
With a rated current of 4 A, a rated voltage of 1000 V AC and a compact 20 × 127 mm cylindrical body, the Mersen S076836 is suitable for drives, converters, rectifiers, power supplies and other industrial installations requiring fast semiconductor protection.
High-speed fuses interrupt fault currents significantly faster than conventional industrial fuses. This rapid response reduces the thermal energy and peak current passed into sensitive semiconductor devices, helping protect diodes, thyristors, rectifiers, power modules and associated electronic components.
The Mersen S076836 combines fast operation with a high voltage rating and compact cylindrical construction. This makes it a practical protection solution for industrial equipment where reliable fault interruption, low let-through energy and clear fuse status indication are essential.
