What is a glass tube fuse?
Glass tube fuse is a type of fuse tube, mainly used to protect the safety of the entire circuit board and circuit by melting its own fuse when there is an abnormality in the circuit (abnormal increase in current, temperature, withstand voltage, etc.).
The key points for selecting insurance pipes are as follows
1. Confirm circuit related parameters
2. Confirm the external dimensions of the fuse
3. Confirm safety certification (to which country)
4. Select the rated voltage of the fuse (rated voltage>maximum operating voltage)
5. Select the rated current of the fuse (rated current>maximum operating current)
6. Consider current pulses
7. Choose the time and current characteristics of the fuse
8. Actual installation testing

acting as a one-stop shop for your fuse replacement needs
FBelec glass tube fuses manufacture various types to meet different needs, including
On/Off Glass Tube Fuses: These simple fuses stop the flow of current when it exceeds a specific limit, protecting your appliances and circuits.
Fast-Blow Glass Tube Fuses: Designed to interrupt circuits quickly in case of sudden surges in current.
Slow-Blow Glass Tube Fuses: Meant to tolerate temporary current surges before interrupting the circuit. These are ideal for appliances with motors that create momentary spikes in current draw during startup.
High-Voltage Glass Tube Fuses: Suitable for applications involving higher voltage requirements.
Here are some general things to consider when choosing a replacement glass tube fuse
Amperage Rating: The fuse's amperage rating must be equal to or higher than the maximum current draw of the device it's protecting.
Voltage Rating: Ensure the voltage rating of the fuse matches the voltage of the circuit.
Physical Size: The fuse needs to fit the fuse holder within your appliance.
If you're unsure about the specific fuse requirements for your appliance, consult the user manual or contact the manufacturer for recommendations. Remember, it's crucial to use the correct fuse type and rating to ensure safety and prevent damage to your appliances.

Classification of glass tube and safety tube
First, according to the installation form, it can be divided into two types: with lead and without lead.
Glass Cartridge Fuse without lead wire needs to be used together with the supporting fuse holder. The advantage of this kind of product is that when the fuse tube is damaged and the fault is eliminated, the fuse tube only needs to be reinstalled into the fuse holder, which is very convenient to replace. The disadvantage is that it needs one more process during production, and the fuse tube needs to be installed after welding the fuse holder, Therefore, in the case of the same specification, the cost of fuse without lead is slightly higher than that with lead for the first production.
The early production cost of lead wire is low, only one process is required and the cost of one fuse holder is reduced. However, when the Glass Body Fuse is damaged, it needs to be replaced by professionals after disassembly, and the replacement cost is very high.
Second, the fusing speed can be divided into several types according to the fusing speed: extra slow break (TT), slow break (T), medium speed (m), fast break (f) and extra fast break (FF). See I in the specification here ² t。
Third, breaking capacity, high breaking (H) and low breaking (L).
Fourth, according to the size, it can be divided into 3.6 * 10, 4.6 * 16, 5 * 20, 6.3 * 30, etc. the specific size depends on each factory. These types of sizes are those with more consumption.
Fifth: according to the classification of safety specification certification, European regulations, Japanese regulations and American regulations.
