Surge Protection Devices (SPDs) are essential components for safeguarding electrical systems from transient voltage spikes. These spikes can originate from lightning, power surges, or switching operations, potentially damaging sensitive equipment. When selecting an SPD, consider its type (Type 1, 2, or 3), voltage rating, and maximum discharge current (Imax). Type 2 SPDs are commonly used for low voltage installations, including residential, commercial, and solar power systems. Proper selection and installation of SPDs enhance the reliability and longevity of electrical infrastructure, ensuring optimal protection for connected devices

Type 1 SPDs:

Designed to be installed at the service entrance.
Protect against high-energy surges from direct lightning strikes.
Suitable for industrial and commercial buildings.

Type 2 SPDs:

Installed at the distribution board.
Protect against residual lightning energy and switching surges.
Commonly used in residential, commercial, and solar power systems.

Type 3 SPDs:

Installed close to sensitive equipment.
Provide localized protection against low-level surges.
Ideal for protecting individual devices and appliances.
