Fuses

The 0498200.UXT-HD is a type of fuse mostly used in HVAC and heating & cooling systems. The UXT-HD fuse is designed to protect electrical circuitry and to prevent overloads that could cause harm to the system.

Application Field

The 0498200.UXT-HD is typically used in air conditioning and heating systems such as air handlers, condensing units, and hot water heaters. It is a specific type of fuse rated for use up to 250 volts of alternating current (VAC), and it can handle up 20 amps (A) of current. It is also appropriate for applications with higher voltages such as 480 VAC and 600VAC.

Working Principle

Fuses use a thin wire called a filament that melts when it reaches a certain current. This melting of the wire is what breaks the circuit and prevents any further current from flowing. The 0498200.UXT-HD fuse has a rating that makes it effective up to 20A of current.

When too much current flows through the circuit, it causes too much heat for the fuse filament wire to handle and ultimately breaks. When the fuse filament breaks, it opens up the circuit and cuts off all power to the system, thus preventing damage.

Advantages

Fuses are relatively inexpensive to use, durable, and easy to replace when they break. Because they are standardized, they are readily available from any electrical supplier or hardware store. Also, because the 0498200.UXT-HD fuse specifically has a low voltage rating, it is safe for use in buildings where there are people and animals present.

Disadvantages

One of the main drawbacks to using a fuse is that it will break when the current is too high, but it will not automatically reset itself like some circuit breakers. To reset a broken fuse, the old one must be removed and replaced with a new one. Also, fuses can be slow to react, especially if the current is slowly increasing. This can cause further damage to the system if the fuse is not replaced quickly enough.

Conclusion

The 0498200.UXT-HD fuse is a valuable safety component to have in any heating & cooling system. It is designed to handle up to 20A of current and can be safely used in buildings with people and animals present. Although it can be slow to react and cannot automatically reset itself, it is still an effective tool for protecting the system.
