Why Choose the Mersen R301062 High-Speed Semiconductor Fuse?
The Mersen R301062, catalogue reference PC32UD45V1800TF, is a genuine Protistor® Size 32 high-speed semiconductor fuse engineered to protect modern power conversion equipment against damaging short-circuit currents. Rated at 1800A, it is designed for applications operating up to 450VAC (IEC) and 500VAC (UL).
Its ultra-fast aR operating characteristic provides outstanding protection for sensitive semiconductor devices including diodes, thyristors and IGBT modules. Precision die-cut fuse elements embedded in solidified silica sand deliver low let-through energy (I²t), rapid fault interruption and high breaking capacity.
The fuse features flush ends with metric threads, silver-plated contact surfaces, a ceramic square body and an integrated striker indicator capable of operating a compatible microswitch for remote indication. These features make it ideal for demanding industrial power electronic installations.
