Fuses are an essential component for ensuring the safety and protection of electrical circuits and devices, and BK/MDL-1-1/8 is one type of fuse with a wide range of applications and a specific working principle. BK/MDL-1-1/8 is a fuse cartridge consisting of a glass tube and two semi-cylindrical metal caps. The spacers allow for the adjustable gap between the contacts. The fuse tube is filled with a mineral based compound that works as an insulator between the contacts. Inside the tube, the metal caps are held by a metal conductor that act as the internal conductor. The caps are designed to have a specific firing configuration to ensure the proper working of the fuse.The fuse cartridge is designed to protect circuits from short circuits and overloads. It works by limiting the amount of electrical current that can flow through the protected circuit. When the amount of electrical current passes the designed threshold, the heat generated by the current will fuse the tube together and open the circuit, breaking the connection and preventing further damage.The BK/MDL-1-1/8 is suitable for use in a variety of applications, including motors, transformers, capacitors, meters, power supply, home appliances, air conditioners, and electrical systems. It is used to protect circuits from electrical shocks, electromagnetic interference, transient voltage surges, overcurrent protection, and short circuits. The fuse can interrupt a large amount of current in a short period of time, helping to protect against excessive current, overvoltages, and false tripping.The BK/MDL-1-1/8 is considered a low-voltage fuse, but it can be used in both AC and DC applications. It is designed to operate in alternating current at a maximum of 600 volts and direct current up to 250 volts. The fuse has a high MRO value of 50kA at a rated voltage of 120/240V AC or 250V dc, and a maximum breaking capacity of 30kA at 250V DC.To ensure the safety of the circuit, the recommended working current of the BK/MDL-1-1/8 is not to exceed 80% of the rated current. The fuse is able to detect rapid changes in the electrical current such as short circuits and resistive overloads, and it can protect against high inrush currents caused by applications such as motor starts. The working principle of the BK/MDL-1-1/8 is based on the timed melting point of the lead-free glass. The lead-free glass is a carefully manufactured material which can resist high temperatures. If the current passing through the fuse reaches dangerously high levels, the heat produced is capable of melting the glass around the conductive path and opening the circuit. This process happens quickly and is usually instant, helping protect the circuit from even the most extreme overloading scenarios.The BK/MDL-1-1/8 is an excellent fuse for protecting electrical circuits and devices and is suitable for a wide range of applications. With its efficient working principle, the fuse ensures optimal safety and protection against overloads, short circuits and other dangerous fault conditions.
