Individual Circuit Protection Devices
Custom Pre-Packaged Assemblies
Custom Pre-Packaged AssemblyPre-Packaged Assemblies (PPAs) are multiple, individual circuit protection devices (SPDs) customized into one easy to install enclosure.
Many times, when installing Surge Protective Devices (SPDs) to protect groups of individual circuits, the situation arises where it might be needed to use several different types of units or models in a small area. This may occur because:
- There are multiple individual circuits to protect.
- It may be advantageous to tie the ground or neutrals together on several SPDs.
- All SPDs may need to be housed in a weather proof or specific type of enclosure.
These situations often call for a custom assembly. Many times, contractors do not have the time or expertise to construct such an assembly. Having the contractor perform this operation may be cost prohibitive as well. Applications like these can be addressed by using Pre-Packaged Assemblies (PPAs).
Pre-Packaged Assembly Applications
The number of uses for multiple, circuit protection devices (SPDs) and how they are assembled is practically unlimited. Constructed PPAs can range from small composite enclosures containing protection for two circuits, to large, custom, metallic enclosures that can protect hundreds of circuits.
Circuit types can be for power, telecom, data, audio, RF or a combination of all of these. They can be any group of individual circuit protection devices in multiples or in combination.
Below are some Custom PPA examples:
 |
|
 |
6 Data SPDs for audio protection in metallic, NEMA 1 enclosure. SPDs are DIN rail mounted with common grounding point at ground bar. Enclosure includes pre-punched knock-outs. |
 |
Multiple power, series-connected SPDs with pre-wired terminal blocks utilizing 3 sides of custom, metallic enclosure. Units protect multiple individual lighting circuits. Assembly has each connection; phase, neutral and ground individually pre-wired with markings to correspond to the ciruit to be protected. Pre-wiring and marking allows for more effecient on-site install by contractor. SPDs are DIN rail mounted and share a common ground point via ground bars. |
 |
PPA includes a combination of series-connected power SPDs with pre-wired terminals, RJ45 connected Data SPDs and Current Loop SPDs. Units are housed in NEMA 12 metallic enclosure. Power SPDs are pre-wired to terminal blocks. All SPDs share common grounding point via ground bar. |
 |
Two different Data SPDs and a Current Loop SPD inside metallic NEMA 1 enclosure. DIN rail installed, including extra space and DIN rail available for future expansion. SPDs share common grounding point via ground bar. |
Get the Right Pre-Packaged Circuit Protection Devices
Pre-Packaged Assemblies can make the application and installation of multiple, individual circuit protection devices much easier for complex systems that have numerous individual circuits to protect.
PPAs also provide an equipotential and singular grounding point for systems with multiple type circuits, such as power, data and communications. PPAs can provide the needed environmental protection utilizing enclosures selected specifically for the installation.
By placing multiple surge protective devices in an enclosure, PPAs can simplify the wiring, reduce installation costs and help ensure proper performance of the SPDs selected for the application. PPAs are a proven method to maximize the benefit of SPD investment.
All devices in PPAs are High Quality, High Performance Surge Protectors. For additional information, please see our PPA video. To get your custom PPA started, contact us today.
