Fuses

Fuses are devices that are designed to protect electrical systems from overloads. BK/ATC-2 is an important type of fuse that has a wide range of applications and is intended for high-amperage protection. It is capable of interrupting an electrical current of up to 300 A, and its operating voltage is between 40A and 300A.

Applications

The primary application of the BK/ATC-2 fuse is in motor control systems. It is commonly used in the control circuits of large industrial motors, such as those used in manufacturing processes. The fuse is also used in computer, communications and HVAC systems, as well as in the protection of medical imaging devices. It is also an important part of the protective device for telecommunications equipment, such as switchgear and relays.

The fuse is also used in automobiles, and is often found in the engine compartments of vehicles. In addition, it is also used in solar systems to protect power components and circuits from damage caused by overloads.

Working Principle

The BK/ATC-2 fuse is designed to interrupt an electrical current when it exceeds a certain level. It operates on a thermal-magnetic principle, meaning that it is both temperature-dependent and current-sensitive. When the operating temperature of the fuse is exceeded, or when there is a fault in the system causing an excessive current flow, the fuse will open and interrupt the circuit.

The fuse has a metallic conduit and a wire filament. When the current exceeds the rated level, the wire filament melts and the metal conduit opens. The current is then interrupted, protecting the device from damage. The thermal-magnetic construction also helps to protect against spikes in current, as it can detect sudden change in current flow and open the circuit before it is damaged.

The BK/ATC-2 fuse is also designed with a variety of safety features to provide additional protection. It has a self-extinguishing feature that ensures that any flames produced by the melting filament are extinguished quickly. It also has a patented inner core sleeve that increases its pull-out strength, making it safer to service. Finally, its high incremental interrupting rating ensures that it can handle a wide range of current levels without becoming damaged.

Conclusion

The BK/ATC-2 fuse is an important type of fuse that is suitable for motor control systems, computer and HVAC systems, and telecommunications equipment. Its working principle is based on a thermal-magnetic principle and it has a variety of safety features to ensure that it can handle a wide range of current levels. It is an effective and reliable way to protect electrical systems from overloads.
