INTRODUCTION

Industrial equipment and machines require defined functions and orderly control to achieve their various process goals. Electrical control panels carry out these functions within manufacturing equipment. An understanding of what they are highlights their critical importance to industry.

In its simplest terms, an electrical control panel is a combination of electrical devices which use electrical power to control the various mechanical functions of industrial equipment or machinery.

An electrical control panel includes two main categories: panel structure and electrical components. The structure of an electrical control panel is a combination of an enclosure and a back panel, similar to a breaker box in a home or office.

The enclosure is a metal box which varies in size and is typically made of aluminum or stainless steel. The number of doors (usually one or two) needed on the enclosure determines its size in most industrial applications.

The enclosure will come with a UL safety rating (508A is typical) an IP rating, and/or a NEMA classification. These listings help users determine properties such as:

·         Indoor/outdoor use

·         Waterproof/water resistance

·         Dust/solid contaminants proofing

·         Hazardous conditions rating

·         Explosion-proof rating

These various classifications should be printed on a metal plate and attached to the enclosure for easy identification and reference.

A back panel is a metal sheet mounted inside the enclosure that provides structural support for DIN rail mounting and wiring ducts. DIN   metal rails feature standardized dimensions and provide a mounting structure for electrical devices. Wiring ducts provide for the routing and organization of wires while also assisting in the control of electrical noise between devices inside the box.

Electrical control panels are essential for industrial automation. They provide higher-level monitoring and control of the various functions of production machinery, allowing manufacturers to define, organize, and meet production objectives.
