Industrial control panels house various components and provide signals to many machines and industrial equipment. These fundamental engineering aspects keep many businesses operating safely and reliably. Continue reading to explore an industrial electrical control panel’s uses and components.

Industrial Control Panel Uses

Industrial control panels (ICPs) have limitations, and understanding their applications allows businesses to use them properly. There are specific requirements and usages for different situations. The National Electrical Code (NEC) defines ICPs as an assembly of two or more power components or combinations of power and control circuit parts. They contain control equipment, such as motor controllers, switches, and relays. UL industrial panels won’t include any externally connected loads.

Industrial Control Panels have several uses, including the following:

  • HVAC systems
  • Access control systems
  • Packaged pumping systems
  • Motor control centers
  • Factory automation equipment

They’ll control everything, including heaters, pumps, motors, and lighting. They’re ideal for industrial automatization, and the high-level control and monitoring allow manufacturers to work more efficiently.

Industrial Control Panel Components

Many people aren’t aware of the different components of the control panels. These parts allow the ICPs to function reliably and safely.

Circuit Breakers

Breakers protect an electrical circuit from damage by sensing excess electrical currents. They can open or break the electrical circuit to stop the flow.


Transformers increase or decrease AC voltages between circuits. They commonly convert 480V alternating current (AC) to 120V AC so the panel’s other devices can use it.

Disconnect Switch

Disconnect switches completely disconnect the panel from the electrical supply. There are several styles and form factors, but they each serve the same purpose. Many electricians will use this component to perform maintenance or complete repairs. The switch will work for emergency stoppages.

Power Supply

A power supply converts AC voltage to direct current (DC) voltage. You’ll typically see the conversion of 480V AC or 120V AC to 24V DC.


Fuses protect electrical circuits before a high current can overload them. These safety devices must be replaced after they operate because open circuits can become dangerous.
