Fuses
Above all, every home and electronic equipment should be safe. And what is responsible for your safety against electricity? First of all, fuses! At the Botland store, we offer a wide selection of professional fuses for various applications. In this category of Botland you will find both a home fuse and a fuse for a car or electronic device. See also proven fuses, thanks to which you will protect components in the electrical circuit in your electronic project from damage!
Of course, you can also buy simpler devices, such as fuses, in which the electric circuit is interrupted due to the melting of the internal fuse.
The electric fuse is the basic electric protection of the electric installation and electric receivers. Such protection is never 100% sure of operation, but it should protect the device, car or house against the effects of excessive current.
The Botland’s offer includes melting fuses, overcurrent, thermal and polymer fuses. In addition to this, you will also find fuse sockets and connectors so that you can place them stably in your device. Choose now what you need the most!

Fuses in our offer
We offer a wide selection of high-quality fuses that you can use in your projects with success and peace of mind. A current fuse is a type of electronic component whose task is to interrupt the circuit when a certain current value (or, for example, ambient temperature) is exceeded.
Types of electrical fuses
A polymer fuse is an electronic element that is used to protect the system against excessive current flow (increase in current). When the critical value is exceeded, the element heats up very much, thus opening the circuit.
After cooling down and eliminating the source of too high current, the fuse can be used again (often it can survive up to about 100 such cycles). Please note that the open circuit of a circuit is never 100%, so a small current will still flow through it after the limit value is exceeded.
Too high a voltage can cause overheating or even breakdown and ultimately damage the circuit components. We have electrical fuses that can be successfully used when connecting your system to a 9 V battery, a 12 V battery or any other source not exceeding 72 V (rated voltage). We offer versions with a current carrying capacity of 0.2 A, 0.5 A, 1.1 A, 3 A, 5 A.
Car fuse
A car fuse is actually a fuse. It is an electronic component that contains an element - a fuse, which is made of an electrical conductor and works in a similar way to a resistor. As a result of the flow of current, the element heats up, and when the current exceeds a certain value, the fuse melts, as a result of which the circuit is opened.
We offer various sets of automotive fuses designed for amperage from 3 A to 30 A (rated current). Our assortment also includes a wide selection of WTA fuses (Fuse Link Apparatus) in versions from 0.1 A to 10 A.
Thermal fuse
A thermal fuse is an electronic element with very low resistance that is designed to disconnect a circuit due to an excessive increase in ambient temperature. Our offer includes fuses operating at 230 V at temperatures of 96° C (10 A), 115° C (1A and 2 A) and 135° C (2 A).
Our offer also includes connectors and fuse sockets as well as thermal bimetallic overcurrent fuses with a rated voltage of 125/250 V AC or 32 V DC - with current carrying capacity (current flow) of 8 A, 16A and 20 A. Intended for, among others: to protect the electrical installation.
Fuses - FAQ
Among the fuses, we distinguish classic tubular fuses (fuses), most often found in size 5x20 mm, as well as special, flat car fuses. Due to the speed of operation, fuses can be divided into fast and time-delay fuses (referred to as WTA-T). There are also so-called polymer fuses (resettable).
Fuses are simple elements designed to protect electrical circuits against the flow of dangerously high current. Depending on its design, the fuse may irreversibly interrupt the current supply (by burning a thin wire) or limit its value (due to a sharp increase in resistance).
The fuse markings depend on their type - for example, the most popular glass fuses (melt fuses) in 5x20 mm tubular housings are available in quick and slow versions (marked with the letter T). In addition to the speed symbol (or lack thereof), the rated current and rated voltage (e.g. 2.5A / 250V) can be found on the fuse housing .
The purpose of the fuse is to cut off or limit the flow of current through the circuit in the event of a failure resulting in an excessive increase in its intensity (e.g. due to damage to one of the rectifier bridge diodes in the power supply ). Thanks to fuses, you can avoid dangerous installation short circuits that may even lead to fire.
