Product Description

Product Description

Our SPD Surge Protective Devices are the pinnacle of defense against transient surge conditions, meticulously crafted to safeguard your cherished electronics from the erratic menace of voltage spikes. Enormous single surge events, like the formidable lightning strike, can unleash an astronomical number of volts, potentially causing catastrophic damage to equipment. However, lightning and utility power fluctuations account for merely 20% of transient surges. The vast majority, an overwhelming 80%, arise internally. These internal surges may not wield the same power as a lightning bolt, but their relentless frequency and persistence can slowly deteriorate sensitive electronic equipment within your premises.


A power surge represents a brief surge of voltage that poses a significant threat to electrical devices, often culminating in their untimely demise. The destruction wrought by surges extends to numerous household essentials, affecting and ultimately diminishing the lifespan of critical devices such as:

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

NEW 2020 National Electrical Code Requirements
In line with the transformative 2020 National Electrical Code, it is now mandatory for all new and renovated homes to be shielded by Listed and Approved Type 1 or Type 2 Surge Protective Devices, raising the bar for protection to new heights.

Type 1:
A permanently connected Surge Protective Device, this robust barrier defends against external and internal surges. It offers versatile installation options, suitable for either the interior or exterior of your home.

Type 2:
This formidable, permanently connected Surge Protective Device is strategically stationed within or adjacent to the breaker box, specifically engineered to tackle both internal and external surges.

Type 3:
Offering enhanced protection, the point-of-use Surge Protective Device delivers an additional layer of defense when used in conjunction with Type 1 or Type 2 SPDs, fully adhering to the 2020 code requirements.

For unmatched protection, deploy a combination of Type 1, 2, and 3 SPDs to ensure your home is entirely fortified against any electrical irregularity.

Installation Instructions

Selection of SPD:
When choosing a Surge Protection Device (SPD) for your power distribution network, it is vital to focus on the fundamental attributes that define an effective lightning protection strategy. This proactive measure is key to ensuring that the building's electrical framework remains robustly shielded.

• SPD
  • Quantity of SPD
  • Type
  • Evaluating the degree of exposure to identify the SPD's maximum discharge current, known as Imax, is an essential step in fortifying your system.
• Short Circuit Protection Device
  • Maximum discharge current, or Imax;
  • Short-circuit current, or Isc, at the installation point.

Other crucial specifications for selecting an SPD are typically predetermined for a particular electrical setup.

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

This sub-sectionDesign of the Electrical Installation Protection SystemThis section offers a comprehensive examination of the standards for choosing a protection system. It considers the unique characteristics of the installation, the specific equipment needing protection, and the environmental conditions.

Location and Types of SPD:


Connection of SPD:
Ensure SPD connections to equipment are as concise as feasible. This strategy significantly reduces the voltage protection level (installed Up) at the terminals of the safeguarded equipment.

The total length for SPD connections to both the network and the earthing terminal block should be kept under 50 cm.

SPD Enclosures: Available choices include SPD in a robust plastic enclosure or a durable metal enclosure.

 

RED: Replace
When the indicator turns RED, it is an unmistakable signal that the product has reached its operational threshold and must be promptly replaced to ensure ongoing protection.
