Product Overview

The BY08 1+2-12.5 Series T1+T2 AC SPD Surge Protective Device is a high-quality device engineered to provide comprehensive protection against transient overvoltages and power surges. It incorporates high-energy MOV (Metal Oxide Varistor) technology, ensuring excellent energy absorption and reliable performance for safeguarding electrical systems and equipment.
This series is available in multiple configurations, including 1P, 2P, 3P, 4P, 1P+NPE, and 3P+NPE, making it highly versatile and suitable for various electrical systems. It supports operating voltages of 150V, 275V, 320V, and 385V, covering a broad range of applications in residential, commercial, and industrial environments.
The BY08 1+2-12.5 series SPD is designed to handle discharge currents ranging from 30kA to 60kA, providing robust protection against high-energy surges caused by lightning strikes, switching operations, and other electrical disturbances. Its high discharge capacity ensures consistent performance, protecting critical devices and minimizing the risk of system downtime or damage.
One of the key features of this surge protector is its modular design with replaceable modules. This allows for easy maintenance and cost-effective operation. If a module is damaged during a surge event, it can be replaced individually, avoiding the need to replace the entire unit. This feature enhances the device's lifespan and reduces maintenance costs.
The BY08 1+2-12.5 series SPD is compact, easy to install, and integrates seamlessly into existing electrical systems. It is particularly suited for protecting distribution boards, industrial control systems, telecommunications equipment, and other sensitive devices.
