031503.2H

Introduction

The 031503.2H is a kind of fuse, which is widely used in many electronic equipment, such as aircraft and missile navigation systems, communications equipment, computers, nuclear power plants, radios, television sets, automotive and other industries. It plays an important role in controlling electric current and preventing short circuits and other phenomena.

Application Field

The 031503.2H fuse consists of two parts—the upper fuse wire and the lower fuse element. Its rated breaking capacity is 600Vac/250Vdc, with rated current range of 0.3-30A. It can be used in DC/AC systems with AC/DC voltage below 600V. Furthermore, it also used in the assemblies and control of protective devices for electric motors, overload protection, compensation capacitors and other equipment of various types of equipment.

Working Principle

The operating principle of the 031503.2H fuse is that when the current of the circuit is too large, the fuse wire will be melted, and the power supply of the circuit will be cut off, thus achieving the purpose of protecting the circuit. The fuse is made of a copper strip, which is heated and becomes red when the current is too large, and the red state quickly melts the fuse wire and breaks the circuit.
