BK/ABC-18

The BK/ABC-18 fuses are the most modern type of low voltage power fuses available in the market today. The fuses are designed to protect equipment and people from overcurrent situations, while allowing normal equipment operation. This fuse is equipped with a thermal fuse element that provides short-circuit protection, and a fuse element that provides overload protection.

The main function of BK/ABC-18 fuses is to protect low voltage circuits from over current, overload and short circuit situations. The fuse will open when the current exceeds the specified value, which is determined by the rated current of the device. This ensures that high current doesn’t harm the device or cause injury to the user. The thermal fuse element will also open if the temperature of the device rises above the maximum temperature allowed. The fuse element provides additional protection in case of overload.

To ensure a reliable performance from the BK/ABC-18 fuses, proper installation is crucial. It is important to choose the correct size and rating for the fuse to ensure protection against all possible overload, over current or short circuit situations. The fuses should be installed in accordance with the National Electrical Code and local codes. The current rating and size of the fuse should be determined by the device’s rated current and voltage.

The BK/ABC-18 fuses are designed with a ceramic cylinder with two terminals. The terminals are connected to a contact that controls the operating temperature of the fuse. The contact is enclosed in a separate ceramic casing to ensure that the thermal fuse element does not interfere with the electrical current. The fuse also contains a special heat conductive material to provide stability and to prevent sudden spikes in temperature. The fuses also have a voltage rating of 600 volts and are UL approved.

The working principle of BK/ABC-18 fuses is simple but effective. When the current exceeds the rated value, the heat generated from the current will cause the thermal fuse element to expand. This will open the contact and break the circuit, thus protecting both the equipment and the user from the risk of overcurrent, overload or short circuit. Once the problem is corrected, the fuse will cool down and the contact will close, restoring the electrical connection.

In summary, the BK/ABC-18 fuses are a reliable and economical solution for low voltage protection. The fuses provide fast and reliable protection against overcurrent, overload and short circuit situations. Proper installation and selection of the correct rated current and size is necessary to ensure proper protection. The fuses also have a working principle based on the thermal expansion of a thermal fuse element, which provides effective protection for both the user and the equipment.
