A fuse is a device used in electrical circuits for protection against overloads or short circuits. Fuses work by creating a low-resistance connection between two points in the circuit. When the current in the circuit exceeds a certain level, the fuse melts, breaking the connection. This prevents the current from leading to potentially dangerous levels or causing equipment damage.

The ATM-25 fuse is a commonly used fuse for overcurrent protection. It is a medium-voltage (MV) fuse rated for 25 amperes with interrupting rating of 20 kiloamperes. It is used in AGT4-400 type disconnect switches, enclosed in a metal enclosure. The terminals are rated for current up to 11kA.

The ATM-25 fuse is designed for protection of low voltage electrical circuits, from overcurrent due to short circuit conditions. Its main application areas are residential construction, commercial buildings, factories, power plants, and other industrial facilities. It is able to withstand temperatures ranging from -60 to 85°C.

The working principle of the ATM-25 fuse is based on the physical process of melting the fusing element. When the circuit exceeds the current rating of the fuse, the fusing element will melt and break the circuit, thus interrupting the current flow in the circuit. The melting process creates a low-resistance bridge between the two terminals of the fuse, which creates the safety gap.

The ATM-25 fuse has several features that make it ideal for applications requiring reliable protection. It is designed with a fast-acting thermal fuse that quickly responds to any current overload. Additionally, the fuse is designed to resist electrical arcing, thus reducing the risk of fire caused by overcurrents. The terminals of the fuse provide an easy and reliable connection to the other components in the circuit.

The ATM-25 fuse is designed to meet the highest safety standards. It is UL listed and rated for compliance with the latest requirements for low-voltage specific applications. Additionally, it is tested and certified for use in protective systems.

In conclusion, the ATM-25 is an effective device for use as overcurrent protection in a variety of electrical applications. Its fast-acting thermal fuse quickly responds to current overloads while its terminals provide a reliable connection between other components in the circuit. Its high safety standards make it an ideal choice for low-voltage specific applications.
