Miniature cylindrical glass fuse 5X20 F 3.15A/250V 006710022

Miniature glass fuse 5x20 mm, 3.15A/250V

This miniature glass fuse in 5x20 mm format is a safety element protecting electrical circuits against overload and short circuit. It is indispensable both in home installations and in electronic devices. Its compact size allows for use in limited space, and the glass housing enables visual control of the condition.

Characteristics and application

A fuse with F characteristic (fast-acting) is designed to protect delicate electronic devices where a quick reaction to current flow is crucial. It will work in power supplies, audio-video equipment and all kinds of electronic circuits sensitive to overvoltage. Because it is a fast fuse, it is not suitable for protecting inductive loads (e.g. motors) that generate inrush currents during start-up.

• Rated voltage: 250V AC – ensures safe operation in standard electrical installations.
• Rated current: 3.15A – ideal for protecting circuits with low power consumption.
• Dimensions: 5x20 mm – universal size fitting most standard fuse holders.
• Fast action (F): protects sensitive components from damage by immediately disconnecting the circuit in the event of exceeding the permissible current.

Installation and replacement

Replacing the fuse is simple and does not require special tools. Remember to disconnect the power before starting the replacement and use a fuse with identical parameters (voltage, rated current, characteristic). Using a fuse with incorrect parameters can lead to damage to the device or even fire hazard. For installers, this means the need to have a set of fuses with different values and characteristics in order to react quickly to customer needs.
