Chip low-voltage fuse is a type of fuse, abbreviated as Low Voltage Fuses with Chip Mounts. The function of a low-voltage fuse is to provide short circuit protection in the circuit. Its advantages include high breaking capacity, strong reliability, small installation area, convenient maintenance, and low price. The disadvantage is that there are few protection methods and the recovery time of the power supply is long.

How to Select Low Voltage Fuses with Chip Mounts

Commonly used low-voltage fuses include various types such as porcelain plug type, sealed tube type, spiral type, filler type, and so on. The ceramic plug type has poor arc extinguishing ability and is only suitable for use at the end of lines with small fault currents. Other types of fuses have arc extinguishing measures, with strong current breaking ability. The closed tube structure is simple, and the spiral type is safer when replacing the fuse tube. The filling material type has a stronger current-breaking ability.

Low voltage fuses are divided into plug-in, spiral, unfilled, and filled types according to their structural forms. According to the range of breaking current, it can be divided into full-range segmented capacity and partial-range breaking capacity. According to the category of use, it can be divided into: general purpose and protection of electric motors.

When selecting patch low-voltage fuses, we need to determine the type of fuse based on the usage conditions. When selecting fuse specifications, we should first select the specification of the melt, then select the specification of the fuse based on the melt, and then have a good coordination between the protection characteristics of the fuse and the overload characteristics of the protected object.

The Impact of Fuse Aging on Usage

After the fuse ages, there is no danger of generating the current that should be cut off and the fuse not blowing. The aging of a fuse is equivalent to a decrease in the rated value (current) rather than an increase, resulting in the circuit being cut off at a small overload current or pulse.

Several Factors Influence the Lifetime of Current Fuses

The lifetime of a current fuse is influenced by several factors. Firstly, the current rating of the fuse plays a crucial role. If a fuse is constantly operating near or at its rated current, it will experience more heat buildup and stress over time, which can shorten its lifetime.

Professional Knowledge of Self-healing Fuses

The operating principle of a self-healing fuse is a dynamic balance of energy. The current flowing through the self-healing fuse generates a certain amount of heat due to the thermal effect of the current (self-healing fuses all have resistance values), and the generated heat is completely or partially dissipated into the environment. The heat that is not dissipated will increase the temperature of the self-healing fuse components. The temperature during normal operation is relatively low, and the heat generated and dissipated reaches a balance.

Guide to Current Fuse Selection

Selecting the appropriate current fuse is crucial for the safety and efficient operation of an electrical system. Firstly, one must consider the rated current of the circuit. The rated current of the fuse should be slightly higher than the normal operating current of the circuit. For example, if a circuit typically operates at 5 amperes, a fuse with a rated current of around 5 - 7 amperes might be suitable. However, it should not be too high, as this may lead to a situation where the fuse does not blow when it should during an overload or short - circuit.

Self Recovery Performance and Working Process of Self Recovery Fuses

Traditional fuses are installed in circuits. When an overcurrent occurs due to a fault or abnormality in the circuit, the fuse itself melts to cut off the current and protect the circuit. However, due to the fact that traditional fuses can only protect once and need to be replaced if burned out, some products still cannot resume operation after troubleshooting or abnormal overcurrent disappears. As a new type of overcurrent protection device, the self-recovery fuse has the function of automatic recovery, which can meet the performance requirements of similar applications.
