Classification of Fuses
Fuse is an element deliberately set in the weak link sensitive to current in the circuit. When the circuit works normally, it has no impact on the protected circuit. Its resistance value is small, preferably no resistance value and no power consumption. When the circuit is abnormal, the current is too large or the circuit has a short circuit, it can quickly cut off the power supply and protect the circuit and other components. There are many types of fuses. The commonly used fuses can be divided into glass tube fuses (low resolution), ceramic tube fuses (high resolution) and polymer self-healing fuses (made of PPTC plastic polymer).
Why use FBELE Glass Fuse and Ceramic Fuse
FBELE provide free samples for real customers.
Full range of UL TUV CUL VDE PSE CCC certification
FBELE adopts high-quality components, some of which are imported from abroad, so its service life is longer
FBELE provides mold opening and customizes products according to customer drawings and samples.
Working Principle of Glass Tube Fuse
When the fuse is open, the heat converted by the internal current will increase the temperature of the melt. When the load is normal T. making current or allowable overcurrent, the heat generated by the current and the heat radiated by melting, shell and surrounding environment, convection and conduction can be gradually balanced; If the heat dissipation speed cannot keep up with E: when heating, these heat will be accumulated part by part in the melt e, so that the melt temperature will rise. When the temperature reaches or exceeds the melting point of the melt material, it will melt, so as to cut off the current and play the role of safety protection.
The Main Parameters of Glass Tube Fuse
- Voltage ratings:
The voltage rating of the fuse must be greater than or equal to the maximum voltage of the disconnected circuit. Since the resistance of the fuse is very low, the voltage rating of the fuse becomes important only when the fuse attempts to blow. When the fuse element melts, the fuse must be able to quickly disconnect, extinguish the arc, and prevent the open circuit voltage from triggering the arc again through the disconnected fuse element.
- Current ratings:
The current rating indicates the current carrying capacity of the fuse under a set of test conditions. Each fuse will be marked with the current rating, which can be numbers, letters or color marks. The meaning of each tag can be found in the product data sheet.
- Breaking capacity / interrupting rating:
The fuse must be able to disconnect the faulty circuit without damaging the surrounding circuit. Breaking capacity refers to the maximum current value when the fuse can safely disconnect the circuit without damage under the rated voltage. The breaking capacity of the fuse must be equal to or greater than the maximum fault current that may occur in the circuit.
- Melting integral:
The fusing integral of a fuse is the energy required to fuse the fuse element of the fuse, also known as the fusing value i2t. The structure, material and cross-sectional area of the fuse element determine this value. Each series of fuses uses different materials and component configurations according to different rated current values, so the i2t of each fuse is determined

What does customer say about FBELE Company
Our company has just started to import Chinese products from this year and is not very familiar with customs declaration and transportation. FBELE has taken the trouble to help us handle the import, which has solved our worries at home. Very very very good service.
We choose FBELE as our partner because FBELE has its own plastic mold factory, which can help us customize products and provide prototypes, which provides a strong guarantee for us to design new products.
