Product Description

Functions of AC Fuse

An AC Fuse is a safety device used to protect electrical equipment and circuits. Its main function is to cut off the current through a fusing mechanism when an overload or short - circuit occurs in the circuit, thus preventing equipment damage and fire risks. The specific functions include:

Overload Protection

When the current in the circuit exceeds the rated value of the fuse, the fuse will blow and cut off the circuit, preventing equipment damage due to overload.

Short - circuit Protection

When a short - circuit occurs in the circuit, the fuse will blow rapidly to cut off the current, avoiding damage to equipment and lines caused by short - circuit current.

Prevention of Electrical Fires

By promptly cutting off the overload or short - circuit current, it prevents the lines from overheating and causing a fire.

Equipment Protection

It protects electrical equipment such as motors, transformers, capacitors, etc. from damage caused by abnormal currents.

Circuit Isolation

When maintenance or repair is required, the fuse can serve as an isolation point of the circuit to ensure safe operation.

Application Scenarios of AC Fuse

AC fuses are widely used in various electrical systems and equipment. The main scenarios include:

Residential and Civil Electrical Systems

Used in home distribution boxes to protect lighting, socket, and household appliance circuits.

Industrial Equipment

Used to protect industrial equipment such as motors, transformers, inverters, and capacitors.

Power Systems

Used for the protection of power facilities such as distribution transformers, switchgear, and distribution lines.

Commercial Buildings

Used in the power distribution systems of office buildings, shopping malls, hotels, etc. to protect electrical equipment and lines.

Public Facilities

Used in the electrical systems of public places such as schools, hospitals, and stations to ensure safe operation.

Renewable Energy Systems

Used in solar photovoltaic systems, wind power generation systems, etc. to protect inverters and distribution lines.

Transportation

Used in electric vehicle charging piles, railway transit electrical systems, etc.

Temporary Power - using Occasions

Such as construction sites, outdoor activities, and other temporary power - using places to provide overload and short - circuit protection.

AC fuses are electrical fuses that work with alternating current circuits. They don't need to be made larger thanks to the alternating frequency of the current supply.

Alternating current is supplied at a voltage that goes from a maximum level to a minimum (0V) level usually 50 to 60 times in a minute. This means that when the strip melts, the arc is easily extinguished when this voltage drops to zero.

The electrical fuse isn't needed to be larger, as the alternating current stops supplying itself.

Low-voltage electrical fuse works in a circuit with a voltage rating that is lower than or equal to 1,500V. These electrical fuses are commonly used in low-voltage electrical circuits and come in different shapes, constructs, and sizes.

They are also cheaper than their high-voltage counterparts and easily replaceable.
