Product Description

Product Description

Introducing our SPD Surge Protective Devices: the pinnacle of protection for your valuable electronics against the unpredictable and menacing voltage spikes. Crafted with meticulous precision, these devices act as vigilant sentinels, safeguarding your equipment from the destructive power of large transient surges. While lightning strikes can unleash a formidable surge of energy, resulting in potential devastation, they account for merely 20% of all transient surges. An astounding 80% of these occurrences originate from within, silently and persistently degrading the performance of sensitive electronics over time, unnoticed yet relentless in their impact.


Power surges: brief voltage overloads posing significant threats to electrical devices, often leading to irreparable damage and reduced lifespan. These surges wreak havoc on an array of household essentials, stealthily reducing their longevity and efficiency, affecting:

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

NEW 2020 National Electrical Code Requirements
The revolutionary 2020 National Electrical Code mandates that every new or renovated home be equipped with Listed and Approved Type 1 or Type 2 Surge Protective Devices, raising the bar for electrical safety and ensuring unparalleled protection.

Type 1:
A robust, permanently connected Surge Protective Device, offering formidable protection against both external and internal surges. Designed for versatile installation, whether inside or outside your home, this device serves as a reliable barrier against electrical threats.

Type 2:
This formidable, permanently connected Surge Protective Device is strategically positioned within or adjacent to your breaker box, tirelessly defending against both internal and external surges, ensuring continuous protection.

Type 3:
An enhanced point-of-use Surge Protective Device offers a superior layer of defense when complemented by Type 1 or Type 2 SPDs, fully aligned with the 2020 code requirements, ensuring unmatched protection.

For the ultimate shield of protection, employ a harmonious combination of Type 1, 2, and 3 SPDs, fortifying your home against any electrical anomalies and securing peace of mind.

Installation Instructions

Selection of SPD:
When selecting a Surge Protection Device (SPD) for your power distribution system, it is paramount to meticulously evaluate the pivotal characteristics that delineate an advanced lightning protection system. This meticulous selection process guarantees that the electrical installation within a building remains robustly safeguarded against unforeseen power surges.

• SPD
  • Quantity of SPD
  • Type
  • Evaluating exposure levels to ascertain the SPD's maximum discharge current, or Imax, is a decisive factor in ensuring effective protection.
• Short Circuit Protection Device
  • Maximum discharge current, referred to as Imax;
  • Short-circuit current, or Isc, present at the specific installation point.

Other indispensable characteristics for selecting an SPD are typically predefined for tailored electrical installations.

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

This sub-sectionDesign of the Electrical Installation Protection SystemThis section delves deeply into the meticulous criteria for selecting an exemplary protection system, considering installation characteristics, vital equipment requiring protection, and the influence of environmental factors.

Location and Types of SPD:


Connection of SPD:
Ensure SPD connections to loads are kept to a minimal length. This effectively minimizes the voltage protection level (installed Up) at the terminals of the protected equipment, enhancing performance and security.

The total length of SPD connections to both the network and the earth terminal block should remain under a concise 50 cm for optimal performance.

SPD Enclosures: Options include SPD housed in a durable plastic enclosure or a robust metal enclosure.

 

RED: Replace
When the indicator turns RED, it is a clear signal that the product has reached its operational limit and requires immediate replacement to sustain effective protection.
