Surge Protective Devices, or SPDs, serve as a robust shield against transient surge conditions that threaten our electrical systems. While monumental single surge events, like lightning, can unleash hundreds of thousands of volts causing immediate or sporadic equipment failure, these dramatic incidents account for just 20% of all transient surges. The unseen culprits behind the other 80% of surge activity lurk internally. Though these internal surges may not boast the vast magnitude of lightning, their frequency and cumulative impact can gradually compromise sensitive electronic equipment, degrading its performance and lifespan.
Product Features
1. 1P+N phase protection tailored for both AC and DC systems, ensuring comprehensive coverage.
2. Equipped with a pluggable module, facilitating effortless installation and seamless maintenance.
3. Boasts a high discharge capacity and swift response time to counteract surges effectively.
4. Features dual thermal disconnection devices, ensuring a heightened level of reliable protection.
5. An innovative green window indicator changes in the event of a fault, while also providing remote alarm control for instant notification.
Power surges, those fleeting yet formidable overvoltage events, silently wage war on your electrical devices, often leading to their untimely demise. These surges pose a significant threat to the durability and operational lifespan of:
As highlighted by the National Electrical Manufacturers Association, the typical household contains approximately $15,000 worth of equipment that remains vulnerable to damage from surges.
Common Causes of Surges:
A staggering 80% of surges originate from internal sources within the premises.

External Sources:
NEW 2020 National Electrical Code Requirements
In accordance with the new mandates, all newly constructed and renovated homes must incorporate Listed and Approved Type 1 or Type 2 Surge Protective Devices, ensuring the safeguarding of your electrical investments.
Type 1:
A steadfast, permanently connected Surge Protective Device that offers a defense against both external and internal surges, with installation flexibility either inside or outside the home.
Type 2:
This permanently connected Surge Protective Device finds its place within or adjacent to the breaker box, providing formidable protection from both internal and external surges.
Type 3:
For an extra layer of security, this point-of-use Surge Protective Device should work alongside Type 1 or Type 2 SPDs, ensuring compliance with the 2020 code requirements.
Embrace the synergy of Type 1, 2, and 3 SPDs to achieve the pinnacle of protection for your home and its valuable assets.

Selection of SPD: Choosing the Ideal Surge Protection Device
For a power distribution system, selecting the optimal SPD to protect a building's electrical installation involves considering key characteristics of the lightning protection system, including:
Other Selection Characteristics: Predefined Parameters for Electrical Installations.
This Sub-Section: A Detailed Exploration Awaits Design of the Electrical Installation Protection System: Crafting a Comprehensive Defense Describes in greater detail the criteria for selecting the protection system based on installation characteristics, equipment protection needs, and environmental considerations.
Location and Types of SPD: Strategic Placement for Maximum Efficacy
Connection of SPD: Optimizing for Enhanced Performance
Connections of a SPD to loads should be minimized in length to lower the voltage protection level (installed Up) on protected equipment terminals. Aim for efficiency!
Ensure the total length of SPD connections to the network and earth terminal block stays under 50 cm to maintain optimal performance.
