3403.0021.11 Datasheet/PDFThe 3403.0021.11 represents a type of fused switch which is mainly used in extremely high-power applications. As the need for higher power and increased safety systems increased, the need for using higher rated fuses arose as well. This type of fuse switch serves as an effective and reliable way to protect electrical circuits from damage due to overloads or short circuits. In addition to that, fuses also help ensure that no current flows through sensitive equipment that may be connected to powerful circuits.
Typically, the fuse switch consists of three main components: a stripped fuse, a switch, and a terminal block. The stripped fuse has two inserts, one in the fuse switch and one in the control panel. The switch is usually mounted on the side of the fuse switch and can be operated manually or remotely. The terminal block is used to attach to the other components of the circuit and then draw power from the fuse.
The main purpose of a fuse switch is to open or close the circuit when it detects an overvoltage or an under-voltage, or when it detects short-circuiting or reverse-flowing current in the circuit. This helps in preventing damage to the components of the circuit due to excessive current. Usually, a fuse switch closes the circuit when an overvoltage is detected, thus helping to protect the circuit from damage.
In case of short-circuiting or reverse-flowing current, the fuse switch opens the circuit to help protect the components of the circuit from the excessive current. This type of fuses is also commonly used in high-power circuits that draw large amounts of current. Such applications require higher rated fuses than regular consumer electronics.
The working principle of the 3403.0021.11 fuse switch is quite simple. When it detects an over- or under-voltage in the circuit, it triggers the switch to open or close the circuit, thus preventing it from further damage. This type of fuse switch also helps in protecting circuits from short-circuiting, as well as reverse-flowing currents. It does this by providing an additional level of protection.
The 3403.0021.11 fuse switch is designed to work in applications that require higher power and increased safety systems. This type of fuses provides an increased level of protection and helps ensure that no current flows through sensitive equipment connected to powerful circuits. As such, it is an important safety device in high-power applications and is commonly found in power plants, factories, and other commercial establishments.
