What is Low Voltage Switchgear?

What is Switchgear?

Switchgear is a general term covering switching devices and their combination with associated control, measuring, protective and regulating equipment, also assemblies of such devices and equipment with associated interconnections, accessories, enclosures and supporting structures, intended in principle for use in connection with generation, transmission, distribution and conversion of electric energy.

There are three primary categories of switchgear:

  • - Low voltage (LV)

  • - Medium voltage (MV)

  • - High voltage (HV)

What is Low Voltage Switchgear?

Now you know what Switchgear is, we best tell you what Low Voltage Switchgear is. Low voltage switchgear is commonly used in industrial and commercial applications, both indoors and outdoors. It’s rated up to 1000V with frequent voltage ratings, including 208V, 240V, 480V, and 600V. Low voltage switchgear uses various components to ensure safe maintenance, protect circuits, and deliver electricity.

Typical applications for low voltage switchgear include air conditioners and heaters, motors, compressors, lighting networks, and many more.

What is the function of Low Voltage Switchgear?

The primary function of LV switchgear is to provide electrical protection against mechanical and thermal stresses of short circuit currents. Without LV switchgear, there is potential for dangerous consequences resulting from excessive currents. Building on the three primary components we touched on in the last section, we can see the primary function of each element.

The incomer assists by withstanding unusual electric current for short limited durations to facilitate the operation of downstream devices. It can also interrupt the maximum value of the fault electric current the system generates. However, it requires an interlocking arrangement with downstream devices.

Air circuit breakers are often the preferred choice for the interrupting device, as it offers simplicity, efficient performance, high normal electric current rating, and high fault withstanding capacity.

Benefits of Low Voltage Switchgear?

Low voltage switchgear offers various benefits and features. A few of these perks and features include:

Safety: Low voltage switchgear provides a high level of safety for electrical power systems by providing protection against over-currents and short-circuits.

Reliability: Low voltage switchgear is designed to be highly reliable, providing uninterrupted power supply and reducing the risk of electrical failures.

Ease of use: Low voltage switchgear is designed to be easy to use, with intuitive controls and monitoring systems that allow for quick and efficient management of the electrical power system.

Cost-effective: Low voltage switchgear is a cost-effective solution for low voltage electrical distribution systems, offering a high level of performance at a competitive price.

LV switchgear offers various benefits and features, although particular offerings may vary slightly depending on the supplier. It’s essential to find an authorized switchgear distributor, like Volt Logic, with quality services and sources.
