BK/F03A-3A

Electrical, Specialty Fuses

The BK/F03A-3A fuse is a specialty fuse designed for electrical work and applications. The fuse has a variety of features and characteristics that make it an ideal choice for many applications where circuit protection is needed. It is commonly used in industrial, residential, commercial, and automotive applications, as well as other locations where circuit protection is required.

Application Field

The BK/F03A-3A fuse is specifically designed for use in electrical and electronic devices and circuits. It can be used in a wide variety of applications including automotive electrical circuits, industrial control panels, electronic circuit boards, residential applications, and much more. The fuse is rated at 10 amperes and has a 13mA interrupt rating, making it suitable for both normal circuit protection and transient protection from arcing and shorts.

The fuse has a high-short circuit current rating of 10,000 amperes, making it suitable for a variety of applications where there is a need to protect against dangerous short circuits. It can handle up to 600 volts of alternating current, which makes it a great choice for applications such as motor safety switches, power transformers, or other similar circuits.

Working Principle

The BK/F03A-3A fuse works by using two strips of metal, made of a heat-resistant metal alloy, lined with a baked enamel insulating material. When the current passes through these two strips of metal, it heats up the metal, causing it to expand. As the metal expands, it pushes against the insulation and creates a break in the current path, thus interrupting the flow of electricity.

The fuse is designed to be very reliable and with its high short circuit current rating, it is capable of protecting circuits from dangerous short circuits. It is also very simple to install and replace, making it a great choice for all types of applications. The fuse is UL and CSA listed, making it suitable for use in a variety of applications.
