Introduction

FWH-70A is a special type of electrical fuse that has been designed to protect both electrical and electronic circuits from damage due to over-currents. The FWH-70A fuse has been widely used in all types of circuits ranging from home lighting circuits to automotive applications. In this article, we will discuss the application field and the working principle of the FWH-70A fuse.

Application Field

The FWH-70A fuse is most commonly used in automotive applications, such as power window or sunroof circuits, control circuits, airbag circuits, central locking systems, anti-lock braking systems, and so on. It can also be used in home lighting circuits, audio and video circuits, and heating, ventilation, and air conditioning circuits. The FWH-70A can also be used in industrial applications, such as control panels, machine tools, power supplies, robotic systems, and so on.

The FWH-70A fuse is rated at 70 amperes and is available in several different case styles, including the popular “J” case. The “J” case is a drop-in style case, which can easily fit into fuse racks and fuse blocks. The FWH-70A fuse can also be found in “L” cases, which are designed for surface mount applications. The “L” case is a flat style case that has a higher current rating than the “J” case.

Working Principle

The FWH-70A fuse works by interrupting an over-current condition in the circuit it is designed to protect. When an over-current occurs, the fuse will break the circuit, meaning that no current will be allowed to flow through the circuit. This breaks the circuit, preventing any further damage to the electrical or electronic components that are connected to the circuit.

The FWH-70A fuse is designed to withstand up to 70 amperes of current, and as such it is strongly recommended that the fuse be the same or higher rating than the maximum current rating of the circuit it is designed to protect. In the event of an over-current, the fuse will quickly break the circuit, allowing the circuit components to remain safe and unharmed.

The FWH-70A fuse is typically used in place of circuit breakers, as it is designed to break the circuit without the need for manual intervention. It allows for a more reliable and efficient way to protect circuits, and the metal oxide construction of the fuse provides excellent protection from over-currents.

Conclusion

The FWH-70A is a very useful electrical fuse that can be used in a variety of applications. It is designed to protect both electrical and electronic circuits from over-currents, and it offers a reliable and efficient way to protect the integrity of the circuits it is designed to protect. The FWH-70A is available in several different case styles, and is rated at 70 amperes, allowing it to effectively protect circuits that draw up to that amount of current.
