The ACH-20 works as a circuit block to protect medium-voltage applications against power surge, during short-circuit and other transients. This type of fuse is primarily used in electric power distribution systems, as a secondary protection circuit element, but is also suitable for protecting other sensitive electrical devices and components. As the fuse\'s rated voltage is much higher than most other fuses, it can be used to efficiently protect high-voltage equipment and circuits.

The ACH-20 is an actuated, vacuum-interrupter type of fuse which uses electromechanical triggering elements to break an electrical circuit. It is controlled by an AC tripping coil, which is connected to the fuse through a current transformer. ACH-20s are extremely reliable, providing high short-circuit protection with low temperature and low voltage drop.

When an overload occurs on an ACH-20 circuit, the current transformer detects it and generates an alternating magnetic field, activating the electromechanical elements inside the fuse. The actuating magnet is energized, driving the arc chute, which carries the arc away from the contacts. This results in the circuit being opened, as the arc passing through the contacts dissipates. When the current returns to normal, the electromechanical elements relax and the arc chute closes the contacts, allowing the circuit to be re-energized.

ACH-20s are used in a variety of applications, including power distribution systems, motor control centers, power control and automation systems, energy management systems, and more. They offer high-speed short-circuit and overload protection, and can handle up to sixty thousandamps of current.

ACH-20s are built with a robust design, which makes them an ideal choice for harsh environmental conditions, such as those found in industrial and mining operations. They are also extremely reliable, thanks to their low-voltage drop design and high-speed switching. The design also ensures a low energy-consumption rating, making them a very cost-effective option.

ACH-20s are typically used in power distribution and automation systems, as they are the perfect choice for providing short-circuit protection while also preventing any disruption to the power supply. They can be used to protect circuits up to sixty thousandamps, making them suitable for heavy-duty industrial applications. Additionally, they are be more reliable and efficient than traditional fuses, providing excellent protection from both short-circuits and overloads.

In conclusion, ACH-20s are an ideal choice for a variety of applications which require reliable power protection. They are lightweight, low-cost, and offer excellent short-circuit protection. Thanks to their robust design and low energy consumption rating, they provide an effective and cost-effective solution for power protection. They can be used to protect a variety of circuits, providing a fast and reliable solution for a variety of power distribution and automation tasks.
