Product Description

Product Description

Introducing our SPD Surge Protective Devices, the unparalleled custodians of your electronics, engineered meticulously to protect against the erratic nature of transient surge conditions. Our devices are your first line of defense against the wrath of voltage spikes. From the dramatic fury of a lightning strike, capable of releasing hundreds of thousands of volts, to the subtler yet persistent internal surges that represent 80% of all transient events, our SPDs have you covered. While external forces like lightning and utility anomalies account for a mere 20% of these surges, it's the internal, insidious surges that steadily and stealthily degrade your sensitive electrical equipment.


A power surge is a brief but intense overload of voltage, a silent saboteur that threatens the integrity of your electrical devices, potentially cutting their lifespan short. The damage perpetrated by surges is far-reaching, impacting and reducing the longevity of crucial household equipment, including:

• 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 a new era of safety for all new and renovated homes, requiring protection by Listed and Approved Type 1 or Type 2 Surge Protective Devices. This sets a higher benchmark for safeguarding your investments.

Type 1:
The permanently connected Surge Protective Device acts as a formidable barrier against both internal and external surges. It provides flexible installation possibilities, suitable for both the interior and exterior of your home.

Type 2:
A robust, permanently connected Surge Protective Device designed to be placed within or near the breaker box. It is strategically engineered to defend against both internal and external surges, ensuring comprehensive protection.

Type 3:
Offering enhanced protection, the point-of-use Surge Protective Device adds an extra layer of security when used in conjunction with Type 1 or Type 2 SPDs. It fully adheres to the 2020 code requirements for the utmost safety.

To achieve unmatched protection, utilize a combination of Type 1, 2, and 3 SPDs. This strategic trio shields your home with an impenetrable barrier against any electrical disturbance, ensuring peace of mind and safety.

Installation Instructions

Selection of SPD:
When selecting a Surge Protection Device (SPD) for your power distribution system, it is crucial to consider key characteristics that define the lightning protection system. This ensures that the electrical installation within a building is effectively safeguarded.

• SPD
  • Quantity of SPD
  • Type
  • Assessing the level of exposure to determine the SPD's maximum discharge current, known as Imax, is a critical factor.
• Short Circuit Protection Device
  • Maximum discharge current, or Imax;
  • Short-circuit current, or Isc, at the installation point.

Other essential characteristics for selecting an SPD are usually predefined for a specific electrical installation.

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

This sub-sectionDesign of the Electrical Installation Protection SystemThis section provides an in-depth exploration of the criteria for selecting a protection system. It takes into account the installation characteristics, the equipment that requires protection, and the surrounding environment.

Location and Types of SPD:


Connection of SPD:
Ensure that SPD connections to loads are kept as short as possible. This minimizes the voltage protection level (installed Up) at the terminals of the equipment being protected.

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

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

 

RED: Replace
When the indicator turns RED, it signifies that the product has reached its limit and must be replaced immediately for continued protection.
