Pack of 20 fast-blow glass fuses rated 250 V 2 A with 4 × 11 mm bodies and axial leads
- Fast-blow action protects circuits from overloads and short circuits
- Rated for AC 250V and 2A continuous current
- 4x11mm glass tube fits standard fuse holders
- 20-piece pack supplies spares for multiple repairs
- Axial wire leads simplify through-hole soldering
What These Fuses Are
A pack of twenty new glass tube fuses rated at AC 250V and 2A. Each fuse measures 11 by 4mm with axial wire leads 27mm long and 0.7mm in diameter. They provide fast-blow protection for circuits in a wide range of electrical equipment.
When To Use Fast-Blow Types
Fast-blow fuses open quickly under overload or short-circuit conditions, making them suitable where sensitive components need immediate interruption. They replace fuses of the same voltage, current and 4x11mm size. The jump is worth it when a slow-blow fuse lets a fault persist long enough to cause damage.
Limits Of The Glass Tube Format
The glass body and alloy caps limit these fuses to the stated AC 250V and 2A ratings. They have no indicator to show a blown element, so visual inspection or a meter is required. The 0.7mm leads suit through-hole mounting but are not designed for high-vibration environments without additional support.

Questions about this item
Will the 4 mm diameter and 11 mm body length fit my existing fuse holder?
Each fuse has a 4 mm diameter and an 11 mm glass body, so it matches holders built for that standard 4x11 mm size.
How do I solder the axial leads without cracking the glass?
Apply heat quickly to the 0.7 mm leads; the 27 mm lead length gives room to grip with pliers as a heat sink while soldering.
When should I replace one of these 2 A fast-blow fuses?
Replace a fuse immediately after it opens, because the fast-blow element is designed to sacrifice itself on the first over-current event.
