Fuses are classified as an electrical component, used to protect electrical systems from damage due to overcurrent or or overload. Specialty fuses like the FL11N20 are designed with specific protection features for specific applications. In this article, we’ll explore the application field and working principle of the FL11N20.

The FL11N20 is a current-limiting fuse with high interrupting rating. It is available in a range of ratings from 0.25 to 125 Amps and is designed for use with AC and DC electrical systems. The FL11N20 is an ideal choice for branch-circuit protection in heavily loaded circuits. It is also suitable for use in motor circuits, where the high interrupting rating helps to protect motors from significant current damage.

The FL11N20 offers a number of features that make it ideal for a variety of applications. These features include high interrupting ratings, low melting I2t, low operating temperature, and fast response time. The fuse\'s ability to trip quickly and reliably helps to prevent damage to sensitive equipment, while its low burning I2t ensures it won’t ever experience a secondary overcurrent. In addition, the FL11N20’s low operating temperature helps it remain suitable for use in confined spaces with limited air circulation.

When it comes to the working principle of the FL11N20, it is based on the melting of a current-limiting element, usually an alloy wire. When the current exceeds the designed level, either as a result of an overload or short-circuit, the wire melts and opens the circuit. The FL11N20 also features a current-sensing element, which senses excess current, triggers a time-delay element, and then trips the fuse. This provides additional protection against sustained overcurrent.

The FL11N20 is designed to be installed in a wide variety of applications, including motor circuits, HVAC systems, PLCs, and more. It is often used in circuit breaker panels, where it provides branch-circuit protection. It is also suitable for use in circuits where high currents may be encountered, such as certain circuit types in oil and gas facilities.

The FL11N20 is a versatile specialty fuse, designed with specific protection features for a variety of applications. It is suitable for use in heavily loaded circuits, such as motor circuits, and provides reliable protection against overcurrents and short-circuits. Its fast response time helps to protect sensitive equipment from damage, while its low melting I2t ensures it won’t ever experience a secondary overcurrent. With its wide range of ratings and features, the FL11N20 is an ideal choice for a variety of protection needs.
