An enclosure gasket is a seal that is used to prevent the ingress of dust and water into the enclosure cabinet or box. The electrical enclosure gasket can be made using different materials, including neoprene, silicone, and EPDM rubber.

5. Electrical Enclosure Cooling System

An electrical enclosure cooling unit helps to remove heat from inside the enclosure and keep the temperature down. These are usually used in enclosures that house sensitive electrical components that can be damaged by heat. There are different types of cooling systems for enclosures.

Electrical Enclosure Fans

These are used to circulate air inside the enclosure and remove heat. Electrical enclosure fans come in different sizes, and the type of fan you choose will depend on the size of the enclosure.

Electrical Enclosure Air Conditioners

These work by removing heat from the air inside the enclosure and circulating cooler air. They come in different sizes, from micro air conditioners for small enclosures to large units for large cabinets.

Electrical Enclosure Heat sink

Another option for cooling enclosures is to use heat sinks. These dissipate heat away from electrical components. An enclosure heat sink can be used in conjunction with fans or air conditioners to provide a more effective cooling system.

6. Electrical Enclosure Ventilation

Electrical enclosure vents help to prevent the build-up of heat inside. They work by facilitating the circulation of air inside the enclosure and keeping the temperature down. There are two main options for enclosure ventilation systems: forced and natural.

Forced ventilation is where air is actively pushed into the enclosure, while natural ventilation relies on the movement of air to circulate it. To prevent dust and water from entering the enclosure, the vents must be fitted with filters.

7. Electrical Enclosure Heater

An electrical enclosure heater helps prevent the formation of condensation inside the enclosure. Condensation can occur when there is a difference in temperature between the air inside the enclosure and the air outside.

8. Electrical Enclosure Lighting System

An electrical enclosure lighting system is used to provide illumination inside the enclosure. This is important for safety as well as for being able to see inside the enclosure. There are two types of these electrical enclosure accessories:

  • Fluorescent Lighting: These are used to provide general illumination inside the enclosure
  • LED Lighting: LEDs provide a more focused and brighter light and are often used for their durability and easy installation.

13. Electrical Enclosure Door Locks

Electrical enclosure door locks are used to secure the enclosure door. These locks help to prevent unauthorized access to the enclosure as they can only be opened with a key. Different types of enclosure locks can be used to secure various installations, such as latch and cam locks.

14. Electrical Enclosure Hinges

Enclosure hinges are used to attach the enclosure door to the enclosure body. They are also made in many different designs, and may be light or heavy duty, depending on the application. Common styles include piano, continuous, butt, and spring. Electrical enclosure hinges must be able to support the weight of the door

15. Electrical Enclosure Handles

Electrical enclosure handles provide a convenient way to open and close the enclosure door. Just like most other accessories, handles come in different shapes, sizes, and materials to meet the specific needs of your application.

16. Electrical Enclosure Rain Canopy

A rain canopy is used to keep the enclosure dry in wet weather conditions. These electrical enclosure accessories are available in different sizes and materials, and may be attached to the side of the enclosure or placed over it.

17. Electrical Enclosure Sun Shield

In order to keep the enclosure cool in hot weather conditions, a sun shield can be used. The electrical enclosure sun shield blocks the sun’s rays from entering the enclosure, and is available in different sizes and materials.

18. Electrical Enclosure Data Pocket

A data pocket is used to store documents inside the enclosure. This helps to keep the documents organized and protected. The enclosure data pocket also ensures the required information about the enclosure and its contents is readily available.

19. Electrical Enclosure Insulation

The electrical enclosure insulation helps to keep the enclosure cool in hot weather conditions and prevent condensation in cold weather conditions. In other words, it regulates the transfer of heat into or out of the enclosure.

Enclosure insulation is available in different materials such as polyurethane, and polyisocyanurate. It also comes in different thicknesses to meet the specific needs of your application.

20. Enclosure Wall Mount

An enclosure wall mount or mounting bracket is used to attach the enclosure to a wall. This helps to save space and keep the enclosure out of the way. Wall mounts are available in different sizes to attach different electrical enclosure sizes and sturdiness for different enclosure weights.

21. Electrical Enclosure Grounding Busbar

The enclosure grounding busbar is used to provide a path for electrical current to flow to the earth. This helps to protect against electric shocks and other dangers. The grounding busbar is made of copper or aluminum, and is available in different sizes.


The list of electrical enclosure accessories is quite long, but this should give you a good idea of the different types that are available.
