FNQ-2-1/4 is a type of electrical specialty fuse.

The fuse is designed for overcurrent protection in industrial applications such as machine tools, appliances, and transformers. It is often found in industrial control panels, motor control centers, and other industrial-grade electrical equipment. It can also be used in HVAC systems and other similar applications.

The FNQ-2-1/4 fuse is a dual element fuse, meaning it provides both primary and backup overcurrent protection. Both elements are fully sealed, and the fuse is designed to trip quickly in the event of an overload or short circuit.

The fuse is made up of two main components, a housing and a blade. The housing is made from a high temperature thermoplastic, and it acts as a barrier between the internal components of the fuse and the external environment. The blade is made from stainless steel and is designed to hold the two fusing elements together. These elements are made from a copper alloy and are filled with a type of fusible metal alloy.

When the current flowing through the fuse exceeds the rated value, the metal alloy in the fuse melts and breaks the circuit, preventing further damage from occurring. When the overload or short circuit is cleared, the fuse must be replaced, as it will no longer provide protection. This is why it’s important to use the correct size and type of fuse for each application.

FNQ-2-1/4 fuses are UL listed and CSA certified. They are available in a range of current ratings from 10A to 600A. They are also rated for voltage up to 600VAC and can be used with both AC and DC circuits.

In addition to providing overcurrent protection, FNQ-2-1/4 fuses are designed to prevent electrical arcing which can cause damage to nearby equipment. The dual element design provides added safety and reliability. This type of fuse can be used for both indoor and outdoor applications.

Fuses are an important part of any electrical system. The FNQ-2-1/4 fuse provides a safe and reliable method of overcurrent protection for a variety of industrial applications. By using the correct fuse for each application, the risk of electrical damage or fire can be minimized.
