Product Description

Product Description

Our SPD Surge Protective Devices are the ultimate guardians of your electronic realm, meticulously crafted to shield your precious devices from the unpredictable wrath of voltage spikes. Even a single, powerful surge event, like the devastating lightning strike, can unleash a torrent of hundreds of thousands of volts, threatening to wreak havoc on your equipment. Astonishingly, lightning and utility power anomalies account for a mere 20% of all transient surges. The silent majority, an overwhelming 80%, arise from within the confines of your facility. While these internal surges may lack the destructive force of a lightning bolt, their relentless frequency and persistence gradually wear down sensitive electronic components.


A power surge is a brief yet dangerous overload of voltage that poses a significant threat to electrical devices, often leading to their untimely malfunction. The destruction wrought by surges is widespread, affecting and reducing the lifespan of numerous household essentials, including:

• Heating and Air Conditioning Systems
• Washers and Dryers
• Water Heaters
• Ranges & Refrigerators
• Lighting
• Entertainment Systems

NEW 2020 National Electrical Code Requirements
In accordance with the revolutionary 2020 National Electrical Code, all newly constructed and renovated homes must be safeguarded by Listed and Approved Type 1 or Type 2 Surge Protective Devices, setting a new benchmark for protection and safety.

Type 1:
A permanently connected Surge Protective Device, offering robust protection against both external and internal surges. Provides versatile installation options, whether for the interior or exterior of your home.

Type 2:
This formidable, permanently connected Surge Protective Device is strategically installed within or adjacent to the breaker box, expertly designed to combat internal and external surges alike.

Type 3:
Augment your protection with a point-of-use Surge Protective Device, delivering an additional layer of defense when used in conjunction with Type 1 or Type 2 SPDs, fully aligned with the 2020 code requirements.

For the pinnacle of protection, deploy a combination of Type 1, 2, and 3 SPDs to comprehensively safeguard your home against any electrical anomaly.

Installation Instructions

Selection of SPD:
Choosing the right Surge Protection Device (SPD) for your power distribution system is of utmost importance. By focusing on key characteristics of the lightning protection system, you ensure that the electrical installation within any building is comprehensively shielded from potential surges.

• SPD
  • Quantity of SPD
  • Type
  • Understanding the exposure levels is pivotal for determining the SPD's maximum discharge current, also known as Imax, thus ensuring optimal protection.
• Short Circuit Protection Device
  • Maximum discharge current, or Imax;
  • Short-circuit current, or Isc, at the point of installation.

Additional critical characteristics necessary for SPD selection are typically predetermined based on the specific electrical installation in question.

• Number of poles in SPD;
• Voltage protection level, Up;
• Operating voltage, Uc.

This sub-sectionDesign of the Electrical Installation Protection SystemExplore the crucial criteria for selecting your protection system in this section. It meticulously considers the installation features, the equipment needing protection, and the surrounding environment, offering a comprehensive guide.

Location and Types of SPD:


Connection of SPD:
Ensure that SPD connections to loads are maintained at the shortest possible lengths. This practice significantly reduces the voltage protection level (installed Up) at the equipment terminals, enhancing safety.

The entire length of SPD connections, extending to both the network and the earth terminal block, should be strictly kept under 50 cm to ensure efficiency.

SPD Enclosures: Options are available for SPD housed in either a plastic or metal enclosure.

 

RED: Replace
A RED indicator signals that the product has reached its operational limit and requires immediate replacement to maintain uninterrupted protection.
