Blade fuse 20 A – code: 14.004.50 – Osculati

Osculati 20 A blade fuse (code 14.004.50)

The 20 A blade fuse Osculati, identified by code 14.004.50, is a protective component designed for insertion in electrical systems where the blade fuse format is used. It is a practical solution for managing and replacing fuses in panels, fuse holders, and power lines that adopt this standard, typical in many applications of electricity and instrumentation in the nautical and plant engineering field.

The function of the fuse is to interrupt the circuit in case of overcurrent, helping to protect wiring and devices. This sheet contains only the available information: nominal current 20 A, maximum nominal voltage 32 V and assorted colors based on amperage capacity.

Features and details

Blade format

This product is a blade fuse, a type widespread for its ease of installation and replacement. The blade format is commonly used in dedicated fuse holders and allows quick visual inspection of the component during routine maintenance activities.

Declared nominal values

• Rated current: 20 A
• Nominal voltage: max 32 V
• Supplier product code: 14.004.50
• Supplier: Osculati S.r.l.

Color coding

The fuse is indicated with assorted colors based on amperage capacity. The color coding is a useful element for quick size identification during installation or replacement, especially when managing multiple protected lines with different values.

Typical applications

The blade fuse from 20 A is suitable for use in low voltage systems within the maximum nominal voltage 32 V, where the use of blade fuses is foreseen. In the nautical and onboard plant engineering field, it can be used as part of the protection of lines and devices, inside panels or fuse holders compatible with the format.

Where it can be used

• Electrical panels and distribution boards that use blade fuses
• Fuse holders for dedicated lines in onboard systems
• Maintenance and restoration interventions on existing systems with blade fuses

When it is useful to have a stock

In operational contexts (boat, workshop, maintenance), having spare fuses of the correct size can simplify interventions and reduce system downtime. The size choice must always be consistent with the protection provided by the system design and with the installed fuse holder.

Operational advantages

Although it is a simple component, a correct and easily identifiable fuse contributes to a more orderly system management. This Osculati model, with identification by code and size, is suitable for professional use in maintenance and outfitting.

Strengths in daily use

• Clear identification: size 20 A and code 14.004.50 useful for reorder and spare parts management
• Practical size: blade type, suitable for quick replacements on dedicated fuse holders
• Visual recognition: color associated with the amperage capacity (assorted according to the manufacturer's standard)
• Suitable for low voltage: declared nominal voltage max 32 V

Usage and important notes

Fuse holder compatibility check

Before purchasing or installing, check that your fuse holder is designed for the blade format used. If in doubt about the format or housing, it is advisable to compare the fuse to be replaced with the spare or refer to the fuse holder/system documentation.

Choosing the correct size

The size 20 A must be selected based on the protection intended for the line. Using a value different from the intended one can compromise the proper protection of the circuit. If you are unsure of the correct size, it is advisable to consult the electrical diagram or a qualified technician.

Voltage limit

The product has a maximum rated voltage of 32 V. Use the fuse within this limit and according to the specifications of the system on which it is installed.

Good maintenance practices

• Power off the circuit before replacing the fuse, when possible
• Check the condition of the fuse holder (clean contacts and proper tightening)
• If a fuse blows repeatedly, check the upstream cause (load, wiring, connections)
