FNQ-2-1/2

FNQ-2-1/2 fuses are commonly used in low-voltage applications, such as residential and commercial applications. This type of fuse is typically used in panelboards, switchboards, and motor control centers. Two main areas of application for the FNQ-2-1/2 fuse are overcurrent protection and short-circuit protection.

The FNQ-2-1/2 fuse has a specialized design that makes it ideal for use in a variety of electrical applications. Its axial-lead constructions allows it to handle high-amperage current without creating hot spots. The fuse is designed to heat up quickly when current passes through it, causing it to blow open and disconnect the circuit. This protects electrical equipment from damage due to overheating.

In order to work correctly, the FNQ-2-1/2 fuse must be connected in-line between the incoming electrical power supply and the load being protected. It should also be installed in accordance with the manufacturer’s instructions and any local or national electrical codes. The fuse should also be connected to a fuse holder or clip that keeps it firmly in place within the electrical circuit.

In order to protect the circuit from overcurrents, the FNQ-2-1/2 fuse is designed with a rated breaking capacity of 80% of its available current. This means that the fuse will blow open when the current in a circuit rises to 80% of its rated value. This is important for protecting electrical circuits from damage due to too much current.

The FNQ-2-1/2 fuse also performs another important function known as short-circuit protection. This is the ability of the fuse to blow open when the short-circuit current exceeds its interrupting rating. This is necessary for safeguarding electrical circuits from excessive short-circuit currents that could cause a fire.

The features of the FNQ-2-1/2 fuse make it suitable for use in a variety of residential and commercial applications. It is important to do research and confirm with local codes to make sure the FNQ-2-1/2 fuse is the right choice for any specific application. Once selected, it should always be installed correctly to ensure proper protection of the electrical circuit.
