Lockable NEMA Enclosures: Key Applications & Top Shielding Options

Many of us secure our residences, workplaces, and cars. It’s an easy, rational measure that aids in safeguarding the most vital aspects of our existence.

Therefore, for certain device designers and engineers, lockable NEMA enclosures are essential. A secure enclosure protects the delicate and important parts of an electronic device and ensures their safety.

In this article, we will explore the various reasons for needing a lockable NEMA enclosure and highlight some of Shinging’s top lockable NEMA enclosures.

Every one of these models provides dependable and robust defense for protecting your device against security threats and environmental factors.

Uses for Lockable NEMA Enclosures.

Numerous applications might need lockable NEMA enclosures. Typically, enclosures for delicate devices located in areas that could be accessed by unauthorized individuals require a locking system.

This requirement is primarily found in outdoor enclosures, but it may also apply to indoor enclosures, especially for industrial ones that safeguard critical systems.

Below are some of the frequently seen uses that need secure NEMA enclosures:

• Security Systems: Numerous security systems require an enclosure to contain their control units. These enclosures must be lockable to stop unauthorized entry to the security system, as they manage essential functions like arming and disarming alarms.

  
  

•  Dangerous Equipment/Materials: Enclosures containing control devices for hazardous equipment frequently require locking mechanisms, as unauthorized entry can lead to very dangerous conditions.

  
  

• Computer Equipment: Sensitive electronic devices, like computer server systems, represent a vital security focus in today's landscape. Unauthorized entry may result in stolen devices or potential data security violations.

Electrical Infrastructure: Essential electrical infrastructure like junction boxes, power supplies, and circuit breakers needs protection not just from impacts and environmental elements but also from unauthorized entry.

Integrated Lock or Padlock?

Usually, you'll find one of two choices used for a secure NEMA enclosure: integrated locks and slots for padlock attachments. Evaluate the advantages and disadvantages of each option while selecting your enclosure:

·Integrated Lock: An integrated lock incorporates the locking mechanism, comprising the cylinder and latch, directly within the door of the enclosure. The latch secures the door and stops it from being opened without a key. These locks provide a high level of security and are difficult to bypass, and they don’t necessitate purchasing any extra tools. Nonetheless, they may cost more than padlock systems and they need additional effort to fix or replace if the operating mechanism gets stuck.

·Padlock: Certain enclosures have a section designed for inserting a padlock shackle. This stops the enclosure from being accessed until the padlock is taken off. This is a simple and affordable method to secure your enclosures, though it necessitates the additional step of purchasing a padlock. If the padlock fails at any point, it can easily be substituted.

Padlocks can occasionally be compromised with bolt cutters (though there are methods to complicate this, like adding metal nuts on the shackle to hinder cutting)

Additional Considerations for Selecting a Lockable Enclosure Box.

When choosing which model of lockable enclosure to specify, here are several other key factors to think about:

·NEMA Rating: Simply having a NEMA rating isn't sufficient — it's important to ensure that your enclosure has the appropriate NEMA rating. An outdoor-rated NEMA 4 enclosure and an indoor-rated NEMA 12 enclosure, for instance, provide notably distinct levels of protection. Shinging’s NEMA ratings guide serves as a vital tool for selecting the appropriate option, particularly if your application needs a waterproof or dustproof enclosure.

·Enclosure Material: A diverse range of metallic and non-metallic enclosure materials is accessible, including stainless steel, polycarbonate, and ABS plastic. Each possesses unique beneficial attributes, ranging from robust durability to inherent resistance against electromagnetic interference. Refer to our enclosure material selection guide for additional details that will assist you in determining the most suitable material for your application.

·Mounting Features: Certain models are created for wall mounting, whereas others can be conveniently attached to a standalone utility pole with a pole mount kit. Furthermore, it's crucial to take into account the enclosure's ability to accommodate any internal mounting hardware like DIN rails that might be required for securing your electrical components. Explore Shinging's range of mounting kits to begin.

·Cooling and Ventilation: Numerous enclosures require cooling and ventilation systems to manage their internal temperatures and avoid moisture accumulation. Discover the types of enclosure accessories offered for each model and evaluate if they meet the requirements of your application. Refer to our guide on calculating temperature increase in enclosures, along with our guide on avoiding condensation.
