8ET Application Field and Working Principle

8ET fuses, also known as "Easy Twin Fuse," are specialty fuse blocks with two positions. In the 8ET family, quick-acting fuses are available to handle overcurrent, overload, and short-circuit protection in electrical devices. This product is widely used in various industries, including automotive, consumer, and industrial applications. It is also useful for secondary protection of rectifier circuits, inductive loads, and switching converters.

The 8ET fuse block has two positions, each one accommodating a pair of quick-acting fuses. The two halves of this fuse block are connected by a clip in the center. This ensures that both fuses are energized simultaneously, and thus allows both fuses to provide protection against overload or short circuit.

The 8ET quick-acting fuse has a straight-through construction, and the fuse contacts are constructed of high-grade brass. When current flows through the fuse, it creates a constriction in the conducting element. The current is concentrated in this area, causing it to heat up and melt, thus breaking the circuit. This feature ensures a fast, reliable fuse operation. Furthermore, the 8ET fuse has a reliable current-limiting feature, providing the maximum protection against circuit overcurrent.

The working principle of 8ET fuses is based on their construction and current-limiting feature. The stationary contact of the fuse contacts is connected to the energized terminal, while the other terminal is connected to the load. When too much current tries to pass through the circuit, the fuse detects it and the fuse element melts, causing a break in the circuit that stops the current.

In addition, the 8ET fuse can be used with transformer secondary protection, DC surge suppression circuits, and other applications. It is also commonly used in motor circuits, battery chargers, and protection of switching power supplies. It can also be used for emergency lighting, industrial lighting, and other electrical devices.

In summary, 8ET fuses are versatile, quick-acting specialty fuses that are popular for secondary protection of various electrical devices. They provide reliable protection against overcurrent, overload, and short-circuit conditions. They can be used in a wide variety of applications, including motor circuits, transformer secondary protection, DC surge suppression circuits, and more. In addition, their construction and current-limiting feature makes them an ideal choice for fast and reliable circuit protection.
