What Is a Panel Cabinet?
A panel cabinet is a protective enclosure used in industrial control panels, housing equipment such as electromagnetic contactors, and circuit breakers. These cabinets safeguard the electrical circuits and devices inside from environmental elements like water, dust, and sunlight, and also prevent electric shock by restricting access to hazardous areas.
Uses of Panel Cabinets
Panel cabinets are widely used in various settings where industrial control equipment is needed. They are commonly found in commercial facilities, typically installed in less accessible areas to manage power supply and control. Signal control cabinets under electric poles, as well as cabinets in schools and station buildings, are also examples. Despite their crucial role, they are often placed discreetly out of plain sight.
Principle of Panel Cabinets
Panel cabinets are primarily made from metal for durability, cost-efficiency, and workability. In environments prone to corrosion, such as coastal areas, materials like stainless steel or plastic are used. They are frequently painted to blend into their surroundings, with customizable color options available. For enhanced corrosion protection, coatings resistant to salt and acid may be applied.
The cabinets usually feature lockable handles to prevent unauthorized access and reduce injury risks. Internally, they contain plates or substrates for organizing control equipment, mounted onto the cabinet’s back.
When installed outdoors, panel cabinets are designed with a roof for water drainage and are structured to prevent dust and water ingress, ensuring a protection rating of IP44 or higher.
