ACF-20 is an electrical specialty fuse which is mainly used to provide circuit protection. It is equipped with a movable metal strip that can break the circuit when the current rises to excessive levels. The metal strip is spring loaded and fastened into position using nuts and bolts. As a result, the ACF-20 provides short-circuit protection, overload protection, and overvoltage protection in electrical wiring systems. In order to ensure that the ACF-20 works correctly, it must be installed properly.

The working principle of the ACF-20 is quite simple. When an overload or short circuit occurs, the current rises to high levels. The movable metal strip is then displaced, breaking the circuit and preventing the current from further increasing. This is due to the fact that the increasing current causes an increase in temperature, which in turn causes the metal strip to expand and to push against the contacts, thus breaking the circuit. The metal strip is designed in such a way that it can only be displaced so much before it breaks the circuit, and the circuit will not re-activate even if the current drops back down to normal levels.

When an ACF-20 is installed properly, it can provide reliable protection against overload, short circuit and overvoltage conditions. The movable metal strip is fastened into position using nuts and bolts and the connections to the external wiring should be done correctly. The ACF-20 should also be tested regularly to ensure that it is working correctly. If any wiring problems are found, the ACF-20 should be replaced immediately.

In summary, the ACF-20 is an electrical specialty fuse that provides protection against overload, short circuit, and overvoltage conditions. It works by using a movable metal strip which breaks the circuit when excessive current levels are detected. The ACF-20 needs to be installed and maintained properly in order to ensure that it works correctly.
