SS-5F-4A-BK

A fuse is an important electrical component used to protect electrical circuits from overload and short circuits. The SS-5F-4A-BK is a type of fuse used in automotive and other applications. This article explains the SS-5F-4A-BK application field, its features, and working principle.

The SS-5F-4A-BK fuse is an automotive blade fuse. It is made of polycarbonate shell and zinc alloy for the contact blades. The SS-5F-4A-BK is rated for up to 25 AMP at 32V DC and has a maximum interrupting rating of 2000A at 32V DC. The fuse is small and compact, measuring only 40 x 19 x 6.4 mm and has a silver plating on the contact blades to ensure reliable contact. It also features a positive lock design to secure the fuse in the socket.

The SS-5F-4A-BK is used primarily in the automotive industry. It is commonly found in the fuse boxes of cars, trucks, and other vehicles. It is also used in some industrial applications, such as for circuit protection of small home appliance motors and electronic equipment. The SS-5F-4A-BK can also be used in signal circuits, audio circuits, lighting circuits, instrument circuits, and power distribution circuits.

The working principle of the SS-5F-4A-BK is based on the fuse element. The fuse element is made of a metal strip that is covered in copper. When an electrical current is flowing through the fuse, the metal strip heats up. If the current exceeds the rated value of the fuse, the metal strip expands and causes a short circuit. This causes the circuit to break and protect the circuit from further damage.

The SS-5F-4A-BK is a reliable and dependable fuse, making it a preferred choice for automotive and other applications. It is small, compact, and features a positive lock design to secure the fuse in the socket. The fuse has a low melting time and is capable of withstanding extreme temperatures. It is also economical, making it a cost-effective solution for circuit protection.
