Miniature fuses from Mersen in 5x20 and 6.3x32 sizes cover ratings from 0.032 A to 30 A. The range holds over 600 products, including IEC quick-acting and time-lag types and high-speed semiconductor types. Stoklink ships worldwide from Turkey on EXW terms, and quotes for project volumes are available on request.
What's in this range
- IEC 5x20 quick-acting fuses, 5SF and 5HF series, rated 250 VAC.
- IEC 5x20 time-lag and medium time-lag fuses, 5ST and 5SM series.
- Semiconductor miniature fuses in 5x20 and 6x32 sizes, FA, FB and SA types, 125 V to 400 V.
- 6.3x32 fuses with clip or axial lead mounting.
- Assortment boxes for service and maintenance stock.
How to choose
- Size: 5x20 and 6.3x32 are not interchangeable, so match the holder.
- Speed: quick-acting for resistive loads, time-lag for inrush from motors, transformers and power supplies.
- Voltage: the fuse voltage rating must be at or above the circuit voltage, 125 V to 500 V in this range.
- Breaking capacity: high-breaking-capacity types are needed where the source can deliver high fault current.
- Mounting: clip, axial lead or PCB style depends on the fuse holder or board.
FAQ
What is the difference between 5x20 and 6.3x32 fuses?
The numbers are the body diameter and length in millimeters. A 6.3x32 body is larger and is typically used for higher voltage and breaking capacity, so the sizes do not fit the same holder.
When should I choose a time-lag fuse?
Use time-lag types where the load has inrush current, such as transformers, motors and capacitive power supplies. A quick-acting fuse may blow on that surge.
Can you supply small quantities and export orders?
Yes. Stoklink ships worldwide from Turkey on EXW terms. Lead time depends on distributor stock.
