Fuses

Fuses are electrical components used to protect overloads and electrical faults in electrical circuits. When an electrical fault or overload occurs, they are designed to blow, effectively disconnecting the circuit so that it won’t succumb to damage. The \'3404.0046.11\' designation refers to a type of fuse developed by Littelfuse called the “F280 Series Time Delay Fuse,” which was specifically designed for AC circuit protection in a wide range of industrial and commercial electrical applications.

Application Field

The F280 Series Time Delay Fuse is designed to protect industrial and commercial AC circuits from short-circuits, line-to-ground faults, and overcurrents. It is suitable for a wide range of applications, from small motor control circuits and lighting circuits in industrial, commercial, and residential facility applications to large high-speed motor control circuits. In addition, the fuse series is suitable for a variety of commercial and industrial applications, including remote alarm and control circuits, computers, process control equipment, medical instruments, and special test and measurement equipment. This type of fuse provides efficient protection for circuits without sacrificing performance or reliability.

Working Principle

The working principle of the 3404.0046.11 fuse is based on a combination of time-delay and current-limiting fuses. The time-delay fuse delays the trip of the fuse and allows high peak currents to pass without blowing. This gives the operator more time to safely disconnect the circuit and repair or replace any affected components. The current-limiting fuse, on the other hand, limits the damage caused by an overload or short circuit by quickly interrupting the circuit as soon as it detects an overload or short. The current passes through the fuse wire until the heat generated by the current overload melts the wire, disconnecting the circuit quickly and safely.

The fuse also features a tested and UL recognized tin-plated copper body construction for superior heat dissipation and long-term reliability. The body of the fuse also features a visual visual trip indicator, allowing operators to easily check the load state of the fuse. This fuse series is also available with a variety of options for mounting and connections, making them suitable for a variety of applications.

Overall, the 3404.0046.11 fuse is an ideal choice for protecting industrial and commercial AC circuits from short-circuits, line-to-ground faults, and overcurrents. With its combination of time-delay and current-limiting features, strong construction, and reliable performance, this fuse series provides reliable protection of electrical circuits in any application.
