The Chint 4-Pole 440V AC Surge Protection Device (SPD) is a high-performance solution engineered to protect electrical installations from lightning strikes, transient surges, and overvoltage conditions. It plays a critical role in safeguarding sensitive equipment and ensuring uninterrupted system operation.
This SPD is designed for AC 50/60Hz systems and supports up to 440V, making it suitable for three-phase electrical networks. With its 4-pole configuration, it provides complete protection across all phases and neutral, ensuring maximum safety in complex power systems.
The device works by diverting excess surge energy away from connected equipment, preventing damage caused by sudden voltage spikes. It is widely used in homes, offices, factories, and solar installations where voltage instability and lightning risks are common.
Built according to international standards such as IEC/EN 61643-11, Chint SPDs are known for their reliability, fast response time, and high discharge capacity, ensuring effective suppression of transient overvoltage.
The modular DIN rail design allows quick installation in distribution boards, while features like fault indication and replaceable modules make maintenance simple and efficient.
Whether you are protecting a solar system, industrial panel, or commercial electrical setup, the Chint 4P SPD provides dependable protection and long-term performance.
