SSQ 400/5K

Fuses

Fuses are electrical devices designed to protect an electrical circuit from overload and short-circuits. When an electrical current exceeds the specified design limit of the fuse, it will break the circuit, interrupting the flow of electricity and protecting against potential damage or destruction of the electrical device.

The SSQ 400/5K is a type of fuse designed for industrial applications. This fuse offers a fast time-delay response and is suitable for circuit protection from both short-term and overloads. It has a AC disconnecting power rating of 400/5K Amps and an AC short-circuit current rating of 10K Amps.

Working Principle

A SSQ 400/5K fuse works by interrupting the flow of electricity when it reaches a certain level. The fuse consists of two parts: the fuse element and the fuse holder. The fuse element is a metal strip, made of lead, nickel, or brass, which is placed inside the holder body. When an overload or a short-circuit occurs in the circuit, the metal strip will heat up and eventually melt, breaking the circuit and protecting the device from further electrical damage. The melting of the metal strip also absorbs the energy of the electrical current, preventing it from reaching the rest of the circuit.

Applications

The SSQ 400/5K is most commonly used in industrial applications, such as for high voltage motors, pumps, and other power-related equipment. It is also used in large electrical systems such as electricity generating plants, and in electrical systems that must withstand high levels of current. The SSQ 400/5K can also be used as a protection device for other types of electrical equipment, such as transformers and other electrical components.

In addition, the SSQ 400/5K is also used in residential applications, such as in residential appliances and heating and cooling systems. This type of fuse is also used in cars and other small electrical vehicles.

Advantages

The SSQ 400/5K fuse has many advantages, including a fast time-delay response that can protect against short-term and overloads. It is designed to withstand high levels of current, which allows it to be used in large and complex electrical systems. It is also easy to install and replace, which makes it a convenient and cost-effective solution for many industrial and residential applications. Finally, its smaller size makes it a more reliable and effective option than other fusing solutions.
