Fuses are mechanical and electrical components that are used in a variety of electrical applications to provide protection against overloads and short circuits. The BK/ATC-10 is a type of fuse that is specifically designed for high overcurrent protection applications such as motor overload and short circuit protection. This fuse utilizes a replaceable element which is mounted within a fused link. The purpose of the BK/ATC-10 is to open and close a circuit when an overload or short circuit is detected.

When the current passing through a circuit exceeds the rated value of the fuse element, a thermal action is created. This thermal action will cause a current to be induced in the molten metal element of the fuse, which will cause it to expand and open the contact. When the circuit is opened, the current will cease and the thermal effect will eventually dissipate, causing the fuse element to again contract and reopen the contact. This cycle will repeat each time the current passing through the fuse element exceeds the rated value.

The BK/ATC-10 fuse is available in a variety of current ratings from .10 to 40 amperes. It is a UL/CSA certified fuse with a rated interrupting current of 2,500 amperes. The fuse body is constructed of a heavy-duty zinc alloy and is designed to provide superior physical protection against abuse and corrosion. The BK/ATC-10 fuse also features a visible indicator to show when the fuse has opened.

The BK/ATC-10 fuse is primarily used for motor overload and short-circuit protection applications. It is ideal for use in commercial and industrial equipment, such as air-conditioners, refrigerators, lighting circuits, and other motor-related applications. It is also suitable for use in electrical equipment that requires high inrush currents, such as induction motors, starters, and contactors. Due to its high surge withstand capability, the BK/ATC-10 is also suitable for DC power protection applications.

The working principle of the BK/ATC-10 has been designed for optimal performance in a variety of applications. It utilizes a replaceable element which is mounted within a fused link. As the current passing through the fuse element increases beyond its rated value, a thermal action is created which causes a current to be induced in the molten metal element of the fuse. This causes the element to expand and open the contact, interrupting the current and preventing further damage to the device being protected.

When the current ceases to exceed the fuse rating, the thermal effect dissipates and the fuse element will again contract and reopen the contact. The thermal action produced by the BK/ATC-10 helps to ensure that it will react quickly in the event of a short circuit or overload. The visible indicator provides an easy way to determine if the fuse has opened, allowing for easy troubleshooting and maintenance.

In summary, the BK/ATC-10 fuse is a type of fuse that is specifically designed for high overcurrent protection applications such as motor overload and short circuit protection. It is UL/CSA certified with a rated interrupting current of 2,500 amperes and is available in a variety of current ratings from .10 to 40 amperes. The working principle of the BK/ATC-10 is based on a replaceable element which is mounted within a fused link. When the current exceeds the rated value of the fuse element, a thermal action is created which induces a current in the molten metal element of the fuse and opens the contact. When the current ceases to exceed the rated value, the thermal effect dissipates and the fuse element will again contract and reopen the contact. The BK/ATC-10 is ideal for motor overload and short-circuit protection applications where a high surge withstand capability is required.
