Our Surge Protective Devices are ingeniously crafted to shield your valuable equipment from the havoc wreaked by transient surge conditions. Imagine the immense power of a single surge, like a lightning strike, capable of unleashing hundreds of thousands of volts, wreaking immediate or occasional havoc on your equipment. However, it's essential to note that while lightning or utility power anomalies contribute to only 20% of such events, a staggering 80% of surges are born from within. These internal surges, though smaller, are far more frequent, and their relentless exposure can insidiously harm sensitive electronics in your facility.
Products Features
1. Powerful 1P+N phase protection tailored for AC/DC systems
2. User-friendly pluggable module design, ensuring effortless installation and maintenance
3. Exceptional discharge capacity with ultra-fast response time
4. Enhanced safety with double thermal disconnection devices for superior reliability
5. Intuitive green window indicator changes upon fault and offers remote alarm control simultaneously
A power surge is a fleeting yet intense overvoltage event capable of inflicting substantial harm on electrical devices, often leading to equipment failure. Such surges are notorious for damaging and shortening the lifespan of:
The National Electrical Manufacturers Association highlights that a typical household holds approximately $15,000 worth of equipment susceptible to surge damage.
Common Causes of Surges:
Remarkably, 80% of surges stem from internal sources
Internal Sources Include:
External Sources Involve:
NEW 2020 National Electrical Code Requirements
As per the 2020 code, all new and renovated homes must be fortified with Listed and Approved Type 1 or Type 2 Surge Protective Devices.
Type 1:
A robust, permanently connected Surge Protective Device that guards against both external and internal surges. Flexible installation, suitable for inside or outside settings.
Type 2:
A permanently connected Surge Protective Device, installed in or adjacent to the breaker box. Shields against internal and external surges.
Type 3:
Offers extra protection as a point-of-use Surge Protective Device. Must be paired with Type 1 or Type 2 SPDs to comply with the 2020 code requirements.
For optimal protection, employ a combination of Type 1, 2, and 3 Surge Protective Devices.

Selection of SPD:
In designing an effective power distribution system, selecting the ideal Surge Protective Device (SPD) hinges on several foundational characteristics. These determine the lightning protection system's capability to safeguard an electrical installation within a building:
Other pivotal characteristics for SPD selection are predefined for any electrical installation.
This sub-section Design of the Electrical Installation Protection System This section delves into the intricate criteria governing the selection of a protection system. It takes into account the unique characteristics of the installation, the equipment requiring protection, and the surrounding environment.
Location and Types of SPD:
Connection of SPD:
To ensure optimal performance, SPD connections to the loads must remain as short as possible. This minimizes the voltage protection level (installed Up) across the terminals of the protected equipment.
For efficient and secure operation, the total length of SPD connections to both the network and the earth terminal block should not exceed 50 cm.
