Storage of sensitive electrical equipment requires additional protective measures. This includes not only shielding such devices from radio frequency or electromagnetic interference, but also from rust. For those exploring their electrical enclosure rust prevention options, Zerust plastabs are thin, lightweight, inexpensive, and highly effective for a full two years. They’re small, slender, rigid polyethylene squares (great for smaller/narrow spaces) with corrosion inhibiting technology molded directly into the plastic. Simply take them out of the package, place them in the electrical enclosure, and the rust protection vapor is activated.

When we talk about electrical enclosures, we’re referring to cabinets that are used for electrical or electronic equipment to mount switches, displays, and knobs. This helps prevent electric shock to users, and also shields the contents of the cabinet from the outside environment, including dust, debris, salt, water, and moisture.

The enclosures are used to protect:

• Circuit breakers, contractors, control panels, and switches
• Distribution boards and panel boards
• Pressurization and purging equipment and systems
• Telephone cabinets

Applications include electric vehicle charging equipment, building electrical and telecommunication rooms, manufacturing plants, utilities, and more. Installation of electronic enclosures is regulated by the National Electric Code (NEC), and possibly local regulations as well.

Why Proactive Electrical Enclosure Rust Prevention is Important

Electrical enclosure rust prevention should be prioritized for a few reasons. The most obvious is that when electronic equipment rusts, it’s no longer going to be effective. Corrosion can damage equipment, leading to constant malfunctions, maintenance, and replacements.

But beyond that, rust on electronics is a possible fire risk. Although rust itself isn’t flammable (it’s a relatively stable compound comprised of iron oxide), it can trigger a short in the equipment – which can cause combustion/fires. Furthermore, if there is rust on a metal surface that is exposed to heat or flames, it could contribute to the flammability of that material.

Plastabs Can Help Prevent Electronics Rust

Plastabs, or rust prevention tabs, can provide several benefits when used in an electrical enclosure.

1. Rust Prevention. Plastabs are designed to prevent the formation of rust and corrosion on metal surfaces. When placed inside an electrical enclosure, they create a protective vapor barrier that inhibits the oxidation process, thus reducing the risk of rust formation. This is especially beneficial in environments where moisture, humidity, or corrosive elements are present.
2. Equipment Longevity. Rust and corrosion can degrade the performance and lifespan of electrical equipment. By using Plastabs for rust prevention, you can extend the longevity of components inside the enclosure. This helps to maintain the operational efficiency of electrical devices, reducing the need for frequent repairs or replacements.
3. Enhanced Reliability. Electrical enclosures often house critical equipment or sensitive components that need to function reliably. Rust and corrosion can cause electrical connections to degrade, leading to intermittent or faulty operation. By preventing rust, Plastabs can help ensure consistent electrical conductivity, reducing the risk of malfunctions, downtime, and potential hazards.
4. Maintenance Cost Reduction. Rust-related issues can lead to costly maintenance and repair efforts. By proactively using Plastabs for rust prevention, you can minimize the need for extensive maintenance, part replacements, or system troubleshooting. This can result in significant cost savings over time and reduce the impact on operational budgets.
5. Safety Enhancement. Electrical enclosures are subject to safety regulations, and rust or corrosion can compromise the integrity of the enclosure’s structure or electrical grounding. By utilizing Plastabs, you can help maintain the structural integrity of the enclosure and ensure proper electrical grounding, thereby minimizing the risk of electrical hazards, short circuits, or equipment failures.
6. Environmental Adaptability. Plastabs are designed to work effectively in various environmental conditions, including high humidity or temperature variations. This adaptability allows them to provide consistent rust prevention in different operating environments, making them suitable for a wide range of electrical enclosure applications.

It’s important to note that while Plastabs can be beneficial for rust prevention, they should be used in conjunction with other appropriate measures, such as regular inspection, cleaning, and proper ventilation, to ensure optimal protection and maintenance of electrical enclosures and their contents.
