Fuses are the primary form of over-current protection used in electrical circuits. They are designed to melt and break an electrical circuit within a certain time frame if the current in the circuit exceeds a predetermined value. The 0498060.UXT-HD fuse is commonly utilized as an alternative to circuit breakers in many applications.

The 0498060.UXT-HD is a Class R fuse, which means that it can provide higher levels of protection against low over-currents than standard Class T fuses. This fuses can be used in residential, commercial and industrial applications, including high-voltage motors, disconnects, lighting, transformers, capacitors, and other applications where a Class R level of protection is required. It is also approved and listed to UL 258-15 and CSA 22.2 No. 8-15.

The 0498060.UXT-HD operates on an interrupting rating of 10kA@240vAC, allowing it to safeguard circuits against extremely high levels of current flow. It features a time-delay rating of 250% minimum at 500% rated current. This means that the fuse will not trip immediately at 500% rated current, but it will allow the current to flow for a short period of time before activating its safety switch. This delay helps protect against nuisance tripping - allowing the system to continue operation without unnecessary disruption.

The 0498060.UXT-HD features a black and red colored metallic case, a large terminal for easy wiring connections, and a test button to verify continuity. The terminal is designed to be compatible with 12–14 AWG (American Wire Gauge) stranded wire, making for an easy installation. The fuse is also rated for up to 10kA Short circuit current capacity, making it ideal for applications where high levels of current flow are expected.

The working principle of the 0498060.UXT-HD is fairly simple. When the current traveling through the circuit rises above the rated value, a small amount of heat generated in the fuse causes it to become slightly soft. Once the heat reaches a certain level, the fuse will melt, breaking the electrical circuit in the process. This breakage of the circuit prevents any further rise in current. The fuse does not have any resetting mechanism, so once it has broken the circuit, it must be replaced in order to restore operation.

In conclusion, the 04960-UXT-HD is a popular alternative to circuit breakers in residential, commercial and industrial applications. It offers a high level of protection with its 10kA@240vAC interrupting rating, 250% minimum to 500% rated current time delay setting, and 10kA short-circuit current capacity. It is easy to install, with its large terminals designed to accept 12–14 AWG wire. Finally, its compact design and simple working principle make it a valuable and reliable component for any electrical system.
