Product Description

Product Description

SPD Surge Protective Devices are meticulously engineered to shield your investments from transient surge conditions. Such transient surges, including large single events like lightning strikes, can unleash hundreds of thousands of volts, potentially causing both immediate and insidious equipment failures. However, a staggering 80% of transient surges are generated internally, though often smaller in magnitude, these internal surges occur more frequently and can, over time, degrade the performance and reliability of sensitive electronics and equipment within your facility. Protect your assets against both the mighty and the minute with our superior surge protection solutions.


A power surge is a fleeting yet powerful overvoltage event capable of inflicting substantial damage on electrical devices. Such surges are notorious for being a prevalent culprit behind the failure of electrical equipment. Power surges can wreak havoc and diminish the longevity of the following critical systems:

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

NEW 2020 National Electrical Code Requirements
All newly constructed and renovated homes must be safeguarded with Listed and Approved Type 1 or Type 2 Surge Protective Devices, as per the latest 2020 regulations, ensuring a future-proof and secure electrical environment.

Type 1:
Permanently connected Surge Protective Device. Protects against both external and internal surges, offering versatile installation options both inside and outside the home, providing comprehensive surge protection.

Type 2:
A permanently connected Surge Protective Device that can be seamlessly integrated within, or adjacent to, the breaker box. It safeguards against internal and external surges, ensuring robust protection at the heart of your electrical system.

Type 3:
Offering an additional layer of defense, the Point-of-use Surge Protective Device. This must be used in conjunction with Type 1 or Type 2 SPDs to fully comply with the 2020 code requirements, delivering enhanced protection.

For optimal protection, employ a combination of Type 1, 2, and 3 SPDs, ensuring your entire electrical system is fortified against a diverse range of surge threats.

Installation Instructions

Selecting the Ideal SPD:
In a power distribution system, to define the lightning protection system and precisely choose an SPD for safeguarding a building's electrical installation, the primary characteristics include:

• Surge Protective Device (SPD)
  • Number of SPDs required
  • SPD type
  • Exposure level to determine the SPD's peak discharge capacity, denoted as Imax.
• Short Circuit Protection Device
  • The SPD's maximum discharge capacity, or Imax,
  • Short-circuit current (Isc) at the installation location.

Other SPD selection criteria are preset for an electrical setup.

• SPD number of poles;
• Voltage protection level, known as Up;
• Operating voltage, referred to as Uc.

This specific section Designing the Electrical Installation Protection System offers a detailed exploration of the protection system selection criteria, tailored to the installation's features, equipment protection requirements, and environmental factors.


SPD Connection:
The connections of an SPD to its loads must be as brief as possible to minimize the voltage protection level (installed Up) on the terminals of the safeguarded equipment.

Keep the total length of SPD connections, from the network to the earth terminal block, under 50 cm.
