ECL055-80E

ECL055-80E is a type of electrical specialty fuses that has different types of applications and working principles. This type of fuse is designed for higher interrupting rating applications in medium voltage switchgear and circuits.

It is a high-voltage, high-amp class fuse that is rated for up to 13.8KV (maximum system voltage) and up to 63A (maximum system ampacity). The ECL055-80E fuse is constructed with a core strand made of resin-coated fusible metal and a metal casing providing a secure, moisture proof environment for the fuse element. The core strand is also filled with granite-like fine particles that are used to increase the fuse’s interrupting rating. The ECL055-80E also has optional spring monitored link construction, providing a reliable and efficient operation.

The main application for the ECL055-80E is in medium voltage switchgear and circuits for overcurrent and short-circuit protection. The fuse is designed to provide reliable protection for those applications, with its high interrupting rating ensuring the fuse quickly breaks the fault current and protects the system. It has a higher melting current capacity than other types of medium voltage fuses, allowing it to be used in applications with higher fault currents. The ECL055-80E also has a high cleaving voltage to help reduce the transient overvoltages created during the fault current clearing. The fuse also has features such as arc suppression and arc reset capabilities to reduce the secondary disturbances during the fault period.

The working principle of the ECL055-80E is to provide overcurrent protection for switchgear and circuits. When the fault current is higher than the maximum melting current capacity of the fuse, the metal core inside the fuse will heat up and melt, breaking the fault current and protecting the adjacent equipment and circuit. After the fault has been cleared, the fuse can be reset manually or automatically using a spring monitor link depending on the application.

In summary, the ECL055-80E is a high-voltage, high-amp class fuse designed for medium voltage switchgear and circuits. It provides reliable protection for those applications with its high interrupting rating and optional spring monitored link construction. Its operating principle is to provide overcurrent protection, breaking the fault current and protecting the adjacent equipment and circuit when the fault current is higher than the maximum melting current capacity of the fuse.
