Fuses

2CLE-40E is a fully shielded type fuse with energy rating of 1000 VAC / 1100 VDC, and interrupting current of 10 kA. It is compliant with RoHS and has a compact design for low profile installation. 2CLE-40E is designed for a wide range of applications including motor control circuits, transformers, telecom systems, building systems, and many other AC/DC power systems.

Applications

2CLE-40E is designed for an extensive range of applications, including motor control circuits, transformers, telecom systems, building systems, and many other AC/DC power systems. It is a reliable option for protection of these components in the most demanding applications due to its compact design and high breaking capacity. 2CLE-40E is rated for currents of 20A to 40A, and is suitable for both AC and DC, making it a versatile choice.

2CLE-40E can also be used in many other applications, such as control circuits, power supplies, battery charge systems, electric power instruments, and more. It is also suitable for disconnection and protection of low voltage switches, wire-to-wire connections, and other components in electrical systems.

Working Principle

2CLE-40E operates using the current interruption by temperature effect. This occurs when the fuse element becomes heated by excessive current flow. The fuse element then begins to expand, gradually increasing the resistance at the fault point. This results in increased heating, and eventually the fuse element overheats and melts, creating an open circuit at the fault. This interrupts the current flow, thus protecting the circuit in case of excessive current.

The 2CLE-40E is constructed with a fuse tube, ceramic insert, and quartz-filled disc. The ceramic insert is a flat, round disc that sits in the middle of the Tube. It is made of a high-temperature ceramic material, and contains a groove that houses the fuse element. The quartz-filled disc is placed on top of the ceramic insert, and it acts as the temperature sensing element.

When the fuse element begins to overheat, the quartz-filled disc expands and the resistance at the fault point increases. This results in further heating of the fuse element, and eventually the element melts and breaks the circuit. The interaction between the fuse element, the ceramic insert, and the quartz-filled disc creates a precise response time that makes the 2CLE-40E fuse ideal for the protection of sensitive circuits.

2CLE-40E is designed to offer rapid response times and excellent current-limiting characteristics. This makes it an ideal choice for applications that require reliable overcurrent protection. The fuse also offers superior contact integrity, as well as low frictional resistance during installation and operation.
