BK/ATC-4

Fuses are important components of modern electrical circuits. They are designed to protect electric objects from excessive temperature, current surge, or other over-current conditions. BK/ATC-4 is a type of fuse specially designed for low-voltage applications. It is a manually operable fuse that can be used in multiple applications and can be applied in a wide range of power and current ratings.

The BK/ATC-4 fuse utilizes a mechanical safety mechanism consisting of a metal strip with multiple device layers of differing materials and resistivities. When the current passes through and exceeds the rating of the device, the metal strip melts and the contacts disconnect, preventing damage to the circuit caused by excessive current. The BK/ATC-4 fuse satisfies the requirements of UL/CSA for the lowest voltage rating on the market at 500Volts. The fuse also complies with IEC and VDE standards and is UL/CSA certified to meet safety and quality requirements.

The BK/ATC-4 fuse can be used in a variety of applications, including lighting circuits, industrial machinery, and switching equipment. It is particularly suitable for low-voltage applications, such as LED lighting. These fuses typically feature bolt-on terminals with a threaded cap for secure installation and can be easily replaced without having to remove the wiring or switchgear. They are also compatible with both national and international standards.

The BK/ATC-4 fuse has a fast acting characteristic with a maximum interruption time of 1 millisecond. This is important to prevent potential damage to the circuit and ensure that it is safe for use. The fuse also has an excellent overload protection capability, with a maximum interrupting rating of 10,000 amperes (typical value).

The BK/ATC-4 fuse is efficient and reliable. It has a wide temperature range of -55C to + 140C with a maximum recommended operating temperature of 85C. It is also resistant to fire damage and has good insulation characteristics. Because the fuse is manually operated, it can be easily and quickly replaced in the event of an over-current conditions.

Overall, the BK/ATC-4 fuse is an excellent choice for a variety of low voltage applications. Its reliable performance, high quality construction, and fast acting function make it a great choice for any low voltage system. It is a proven solution for providing safe and efficient power in industrial and commercial applications.
