OSFE006.V Application Field and Working Principle

Fuses are an essential device in electricity distribution and control systems. In the form of a fuse or fuse-breaker, it is typically mounted between two wire conductors or terminals and is designed to open or blow when a certain amount of electric current passes through it. In a wide range of electrical installations, fuses are used to protect a system from overheating and fire caused by excessive current. A fuse is a relatively simple device, consisting of a metal casing filled with a metal conducting element, usually connected to an external conductor.

OSFE006.V Fuses

The OSFE006.V fuses are a type of electrical fuse designed for use in medium voltage applications. This device is applicable for use in indoor and outdoor high voltage circuit breakers. It is also used in applications such as motor control centers, power distribution panels, and HVAC systems. The OSFE006.V is a thermal-magnetic type of fuse, which means that it also functions as a circuit breaker. This means that, when the temperature inside the fuse exceeds a certain level, the fuse element melts and breaks the circuit. In addition to the thermal protection, these fuses also provide additional protection due to their magnetic trip characteristics.

The OSFE006.V fuses are available in a variety of different sizes and amp ratings and come with clips for easy installation. The amp rating is indicated on the fuse its rating label and should always be checked before installation. The proper rating will depend on the amount of current that will be flowing through the circuit. The clips included with the fuse are designed to ensure a good contact between the fuse and the device.

Working Principle

The OSFE006.V fuse operates on a thermal-magnetic principle. This means that the fuse is designed to open the circuit when the current through it reaches a certain level. This level is indicated on the rating label. As more current passes through the fuse, it will heat up, and when it reaches a certain temperature, the fuse element melts and the circuit is broken. This melting action is what is referred to as fusing action.

When the circuit is no longer current-carrying, the fuse element will cool down and the circuit will be restored. Other than due to the melting of the fuse element, the fuse can also trip due to its magnetic properties. This is referred to as magnetic tripping, and it occurs when the magnetic force caused by the current passing through the fuse is greater than the force of the spring that holds the fuse element in place. When this happens, the fuse element is pushed out of place, breaking the circuit.

Conclusion

The OSFE006.V fuses are an essential device in electricity distribution and control systems. This device operates on a thermal-magnetic principle, meaning that it will open the circuit when too much current passes through it. This fuse is suitable for medium voltage applications and can be used in a variety of settings, such as motor control centers, power distribution panels, and HVAC systems. It is important to check the amp rating of the fuse before installation in order to ensure that it is the correct size for the application. By using a correctly sized fuse, a system can be protected from damage due to overheating and fire caused by excessive currents.
