Product Description

Product Description

Our SPD Surge Protective Devices epitomize the pinnacle of protection against transient surge conditions. Crafted with meticulous precision, they are the steadfast defenders your cherished electronics need against the unpredictable surges of voltage spikes. Massive single surge events, like the daunting lightning strike, can unleash voltages in the hundreds of thousands, leaving equipment vulnerable to devastation. Yet surprisingly, only 20% of transient surges are due to lightning and utility power anomalies. The remaining 80% are internal, stealthy threats that, while lacking the raw power of a lightning bolt, insidiously chip away at the integrity of sensitive electronics within your facility over time.


A power surge is a brief but intense overload of voltage that poses a serious risk to electrical devices, often leading to premature failure. The damage inflicted by surges extends across a spectrum of household essentials, significantly impacting and reducing the lifespan of:

• 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 all new and renovated homes must be protected by Listed and Approved Type 1 or Type 2 Surge Protective Devices, setting a new benchmark in safety and protection.

Type 1:
This is a permanently connected Surge Protective Device, serving as a formidable barrier against both external and internal surges. It offers flexible installation options, suitable for both the interior and exterior of your home.

Type 2:
A robust, permanently connected Surge Protective Device strategically located within or near the breaker box, crafted to counter both internal and external surges effectively.

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

For the ultimate in protection, the strategic use of Type 1, 2, and 3 SPDs is recommended to comprehensively guard your home against any and all electrical anomalies.

Installation Instructions

Selection of SPD:
Selecting the right Surge Protection Device (SPD) for your power distribution network is pivotal. Key characteristics of the lightning protection system must be evaluated to ensure robust safeguarding of your building's electrical install.

• SPD
  • Quantity of SPD
  • Type
  • Determining the exposure level leads to identifying the SPD's maximum discharge current, Imax, a vital consideration for your system's protection.
• Short Circuit Protection Device
  • Maximum discharge current, known as Imax;
  • Short-circuit current, referred to as Isc, at the installation point.

Additional crucial characteristics for choosing an SPD are often predetermined based on the specific electrical setup.

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

This sub-sectionDesign of the Electrical Installation Protection SystemThis section delves into the comprehensive criteria for selecting a protection system, considering installation traits, equipment protection needs, and environmental factors.

Location and Types of SPD:


Connection of SPD:
It is imperative to keep SPD connections to loads extremely short. Doing so reduces the voltage protection level (installed Up) at the terminals of the protected equipment.

The entirety of SPD connections to both the network and the earth terminal block must be limited to under 50 cm.

SPD Enclosures: Choose between SPD in a durable plastic enclosure or a sturdy metal enclosure.
