Fuses have been around for centuries and have been used to protect circuits and equipment from over-current events.An ATM-20 fuse is an example of this type of fuse, used for low-voltage applications, such as providing protection to motors, lighting circuits, appliances, and transformers.Here, we’ll cover the application field and working principle of the ATM-20 fuse.

The ATM-20 is a slow-blow fuse, which means it has a time rating and delayed action. It is designed to open the circuit in the event of a sustained over-current, or to open in the event of a sharply increasing current. This fuse is UL Recognized and carries a current rating of 20 amps. It is used primarily in the protection of low voltage motors and circuit control applications.

The working principle of this fuse is relatively simple. Due to its design, the ATM-20 allows slightly higher current to flow through it than what is normally permitted by other fuses, while still protecting circuits and equipment in the event of a sustained over-current. The surge of current causes a heated element on the fuse to heat up. This causes the fuse to open, thus cutting off power to the circuit or equipment.

The benefits of using the ATM-20 fuse include its UL Recognized rating, its delayed action, and its current rating of 20 amps. This fuse is cheaper to use than other UL recognized fuses, and is capable of protecting circuits from sustained over-currents without tripping unnecessarily. It is also versatile, and can be used in a variety of applications, including motors, lighting circuits, appliances, and transformers.

Now that you know a bit about the ATM-20 fuse, you can understand why it’s becoming more popular in the industry. Its UL recognition, delayed action, and current rating make it an ideal choice for low voltage applications. It is also very affordable, making it a great alternative to its more expensive counterparts.
