8020.0605.PT Application Field and Working Principle

In this article, we discuss the application field and working principle of 8020.0605.PT , a type of fuse.

What is the 8020.0605.PT ?

The 8020.0605.PT , part of the ABB industrial fuses series, is a type of fuse designed for industrial applications. This fuse features quick-act high breaking capacity to protect complex electrical systems against short circuit and overloads. It can be widely used in industrial equipments such as switchboards, switchgear, AC/DC distribution systems and other safety devices.

Application Field of 8020.0605.PT

The 8020.0605.PT is suitable for use in industrial distribution and AC/DC systems, where fault current levels are moderate and unpredictable. It has the capacity to safely interrupt rated currents from 16A to 630A with a maximumLet-through current (Iwt) without any arcing. This fuse is appropriate for 1 phase 2 pole application.

Working Principle of 8020.0605.PT

The 8020.0605.PT functions in two ways as an over-current element and as a voltage-limiting element. When a fault occurs, it interrupts the circuit by melting the fuse element, which is made from an alloy of silver and copper. As the electrical current increases, the heat generated by the current will melt the fuse element, resulting in an open circuit. This prevents further current flow and stops the fault from getting worse.

The 8020.0605.PT also works as an over-voltage protection device. It has a pre-set voltage threshold, and when this threshold is exceeded, the fuse element will melt and interrupt the circuit. This prevents the circuit from being destroyed by too much voltage.

Conculsion

The 8020.0605.PT is an industrial fuse designed for use in industrial distribution systems. It features quick-acting and high-breaking capacity, and it can safely interrupt current from 16A to 630A. It works as both an over-current and over-voltage protection device, and it is appropriate for 1 phase 2 pole applications.
