Miniature cylindrical glass fuse 5X20 T 1.25A/250V 006710047

Safety and protection of electrical circuits

This miniature cylindrical fuse, made of glass, is a safety element protecting the electrical installation from the effects of overloads and short circuits. It is designed to work with circuits with a voltage of up to 250V and a current of 1.25A. Its small dimensions (5x20mm) allow it to be used in a wide range of devices and installations.

Construction and application

The glass fuse, also known as a fuse, is a basic element of short-circuit protection. It works on the principle of the fusing wire inside the glass housing when the current exceeds the permissible value. This particular model, with T characteristic (time-delayed), is particularly useful in circuits exposed to short-term current surges, e.g. when starting motors or transformers. The delayed characteristic allows you to avoid unnecessary disconnection of the circuit during momentary overloads.

Key features and benefits

• Small dimensions: 5x20mm – ideal for use in electronic devices and installations with limited space.
• Rated voltage 250V: Ensures safe operation in standard electrical installations.
• Rated current 1.25A: Well suited for protecting delicate electronic circuits and devices with low power consumption.
• T characteristic (delayed): Allows momentary exceeding of the rated current without disconnecting the circuit – useful when starting devices with motors or transformers.
• Made of glass: Provides good visibility of the blown fuse, making it easier to identify damage.
• 10-piece pack: Allows you to stock up on spare fuses, which is practical for installers and end users.

It is important to choose the right fuse for the protected circuit – too high a rated current may damage the installation or device, and too low a current – frequent blowing of the fuse and disturbances in the system operation.
