What is Switchgear?

Switchgear is a generic term used to describe a wide variety of industrial electrical control equipment. It includes all the control and switching devices necessary for the operation and control of an electrical power system.

Types of Switchgear

Switchgear can be broadly classified into two main types, as follows:

  • Low Voltage Switchgear: This type of switchgear is generally used to control and protect low voltage electrical systems. It includes manual and automatic switching devices such as circuit breakers, fuses, contactors and relays.
  • Medium Voltage Switchgear: This type of switchgear is typically used to control and protect medium voltage electrical systems. It includes switchgear components such as circuit breakers, switches, relays, and current transformers.

Applications of Switchgear

Switchgear is used in a variety of industries, including oil and gas, automotive, marine and aerospace. It is also commonly used in industrial and commercial applications, such as power distribution, control and protection of electrical systems.

In addition to controlling and protecting electrical systems, switchgear can provide isolation of circuits, enabling workers to safely perform maintenance on electrical equipment without having to shut off the power supply.

Advantages of Switchgear

Switchgear has many advantages over traditional electrical control systems, including:

  • Improved safety: Switchgear provides the necessary protection for workers by reducing the risk of electrocution and other safety hazards.
  • Reduced costs: Switchgear eliminates the need for costly wiring and other components, as well as reducing maintenance costs.
  • Increased efficiency: Switchgear enables efficient and reliable operation of electrical systems, and enables faster and more reliable operation of equipment.
  • Improved control: Switchgear provides more precise control over electrical systems, enabling better monitoring and protection of electrical equipment.


Switchgear is an essential component of any electrical system, and is used in a variety of industries to provide protection and control over electrical systems. Switchgear provides improved safety for workers, reduces costs and increases efficiency of electrical systems, and provides improved control.
