Product Description

Product Description

Introducing Taimu Electrical's SPD Surge Protective Devices: the unrivaled protectors of your electronic sanctum, meticulously engineered to defend against the capricious onslaught of voltage surges. Imagine the formidable force of a lightning strike, unleashing a torrent of hundreds of thousands of volts, threatening to compromise your critical equipment. While such dramatic events account for a mere 20% of surges, the true menace lies within-the stealthy, internal surges constituting a massive 80%. Though less dramatic than a lightning strike, their relentless occurrence can subtly but surely degrade sensitive electronics within your premises.


Power surges, those ephemeral voltage overloads, pose a serious threat that can lead to the premature failure of your cherished electrical devices. The impact of these surges reverberates through an array of household staples, inevitably curtailing their longevity and efficiency:

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

NEW 2020 National Electrical Code Requirements
In accordance with the landmark 2020 National Electrical Code, every new and retrofitted home must be equipped with Listed and Approved Type 1 or Type 2 Surge Protective Devices, establishing an elevated benchmark of security.

Type 1:
A robust, permanently connected Surge Protective Device that serves as a formidable defender against both external and internal voltage surges. Its versatile installation allows it to be placed either within or outside your home, providing flexible protective options.

Type 2:
A vigorous, permanently connected Surge Protective Device, strategically installed near or within the breaker box to effectively combat both internal and external surges, ensuring comprehensive coverage.

Type 3:
Offering supreme protection, this point-of-use Surge Protective Device delivers an added shield when used alongside Type 1 or Type 2 SPDs, aligning perfectly with the 2020 code standards for optimal defense.

For the ultimate in electrical safety, deploy a strategic blend of Type 1, 2, and 3 Surge Protective Devices, ensuring your home stands impregnable against any electrical disturbances.

Installation Instructions

Selection of SPD:
When embarking on the selection journey of a Surge Protection Device (SPD) for your power distribution system, it's imperative to focus on pivotal characteristics that shape the lightning protection mechanism. This guarantees that the electrical framework within any structure is thoroughly shielded, offering peace of mind and sustained safety.

• SPD
  • Quantity of SPD
  • Type
  • Evaluating the exposure level to pinpoint the SPD's maximum discharge current, famously referred to as Imax, is an absolute necessity in your selection process.
• Short Circuit Protection Device
  • Maximum discharge current, or Imax;
  • Short-circuit current, or Isc, at the precise installation point.

Other crucial characteristics necessary for the selection of an SPD are typically predefined, tailor-made for a specific electrical installation scenario.

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

This sub-sectionDesign of the Electrical Installation Protection SystemThis section delves deeply into the meticulous criteria needed for selecting a protection system. It thoroughly considers the installation specifics, the equipment that requires safeguarding, and the environmental conditions.

Location and Types of SPD:


Connection of SPD:
Ensure SPD connections to loads are kept remarkably short to minimize the voltage protection level (installed Up) at the terminals of the safeguarded equipment.

The comprehensive length of SPD connections to both the network and the earth terminal block should be meticulously kept under 50 cm.

SPD Enclosures: Available options are SPD housed in a plastic enclosure or encased within a metal enclosure.

 

RED: Replace
When the indicator turns RED, it is a clear signal that the product's limit has been reached. It must be replaced promptly to ensure ongoing protection and efficiency.
