Fuses are an important part of any electrical system. They are designed to protect circuits against overloads and short circuits—circuits can be attached in an array or series to protect multiple circuits from overcurrents, which can lead to dangerous arcs and even fires. The 5CLE1-40E fuse is a two-part molded-case fuse assembly consisting of a short-circuit-resistant internal fuse element and a pressure-responsive metallized body. The fuse is specifically designed to meet UL and CSA standards for use in an array to provide overcurrent protection in industrial, commercial, and residential applications.

The 5CLE1-40E fuse is designed for use in branch circuits, and has a voltage rating of 600 Volts, 10,000 amps maximum interrupting rating, and 100,000 amperes, meaning it can effectively protect against short circuit currents. It is UL- and CSA-listed for use in the United States and Canada, and is designed to meet UL 248-14 for applications in protective circuits within electrical equipment. Additionally, the 5CLE1-40E is a fast-acting fuse that will provide reliable protection in as little as 10 milliseconds.

The 5CLE1-40E is a time-delay fuse, which means that it will not open until the current exceeds the rated value for a given time period. This feature is particularly useful in motors with high inrush currents. The time-delay feature also provides protection against nuisance trips, which can cause an disruptive breaks in power supply.

This fuse assembly can be used in several application fields, such as industrial and residential appliances, home automation systems, automotive and telecommunications systems, and other industrial applications. It also has uses in motor drives, protection relays, chargers, and UPS systems.

In terms of its working principle, the 5CLE1-40E fuse is a two-part assembly consisting of an internally insulated, short-circuit-resistant fuse element and a pressure-responsive outer body. The fuse element is made of a metal alloy that melts when exposed to an over-current or short-circuit condition. When this happens, the inner material disperses the energy absorbed from the flowing current, while the outer body applies pressure to the fuse element.

When the current exceeds the rated amount, the pressure applied by the outer body causes the fuse element to melt, thereby opening the circuit and ceasing the flow of current. At the same time, the pressure from the outer body prevents current from flowing in the other direction, further protecting against short circuits.

As a fast-acting fuse, the 5CLE1-40E is ideal for protecting electrical circuits in multiple applications. Its time-delay feature allows it to provide enhanced protection against unpredictable surges or transient overloads and nuisance trips, thereby increasing the reliability of power supply. With its UL- and CSA-listing and its ability to provide reliable protection, the 5CLE1-40E is a must-have for any application that requires reliable overcurrent protection.
