Max Hauri Feinsicherung 2.5A Fast-Blow 250V 5x20mm
The Max Hauri Feinsicherung is a fast-blow glass fuse rated at 2.5 A and 250 V, designed for overcurrent protection in electrical circuits. It features a clear, compact 5 x 20 mm cartridge format for straightforward installation in fuse holders.
Fast-blow (F) characteristic trips quickly to protect sensitive components from overcurrent damage
5-piece set provides immediate replacement capacity for maintenance and repair tasks
250 V rating suitable for standard low-voltage electrical installations
Clear glass body allows visual inspection of the fuse element for quick fault identification
What sets this fuse apart
The fast-blow response time distinguishes this fuse from slow-blow types, making it ideal for circuits with sensitive electronics that cannot tolerate sustained overcurrent. The 5 x 20 mm standard format ensures compatibility with common fuse holders used in Swiss electrical installations.
Ideal for...
Electricians and maintenance technicians working on residential and commercial electrical distribution boards. The 2.5 A rating suits low-power circuits such as lighting, signal, and control installations where precise overcurrent protection is required.
Application of Max Hauri Feinsicherung
Identify the correct fuse holder matching the 5 x 20 mm format
Ensure the circuit is de-energized before inserting or replacing the fuse
Insert the fuse until it clicks into place in the holder
Verify the 2.5 A rating matches the circuit's designed current load
Max Hauri is a Swiss manufacturer of electrical protection components, specialising in fuses and fuse holders for low-voltage installations. The brand focuses on standardised, reliable overcurrent protection solutions for residential and commercial applications. Max Hauri products are distributed through specialist electrical wholesalers in Switzerland.
A fast-blow (F) fuse trips immediately when current exceeds its rating, protecting sensitive electronic components from damage. It is used in circuits with devices that cannot tolerate even brief overcurrent, such as signal and control circuits.
5 x 20 mm refers to the fuse cartridge dimensions: 5 mm diameter and 20 mm length. This is a standard glass fuse format compatible with most common fuse holders in Swiss electrical installations.
The fuse is rated at 2.5 A (amperes) and 250 V (volts). The 2.5 A rating indicates the maximum continuous current the fuse can carry, and 250 V is the maximum voltage it can safely interrupt.
The delivery includes 5 individual 5 x 20 mm fast-blow fuses, each rated at 2.5 A and 250 V, in a single package.
Max Hauri fuses are manufactured to meet relevant Swiss and European electrical safety standards for low-voltage fuse protection. The 250 V rating and fast-blow characteristic comply with standard requirements for circuit protection in residential and commercial installations.
