product detail
Product Overview
- The BY08II-40 Series T2 AC SPD Surge Protective Device is a high-performance device designed to safeguard electrical systems from surges and transient overvoltages. Equipped with high-energy MOV (Metal Oxide Varistor) technology, it ensures excellent surge absorption and reliable protection for sensitive equipment and installations.
- This surge protector is available in various configurations, including 1P, 2P, 3P, 4P, 1P+NPE, and 3P+NPE, offering flexibility for different wiring systems and applications. It supports a wide range of operating voltages, including 150V, 275V, 320V, 385V, and 440V, making it suitable for residential, commercial, and industrial environments.
- The BY08II-40 series SPD is designed to handle discharge currents from 20kA to 40kA, providing robust protection against lightning strikes and power surges. Its high discharge capacity ensures that it can withstand and dissipate significant energy levels, maintaining the integrity of connected devices and systems.
- A standout feature of this series is its modular design with replaceable modules. This allows for quick and easy maintenance, as damaged modules can be replaced without dismantling the entire device. This feature enhances the device's durability and cost-effectiveness over time.
- With a compact design, the surge protector is easy to install and integrates seamlessly into existing electrical systems. It is particularly well-suited for protecting equipment such as distribution boards, industrial control systems, telecommunications devices, and household appliances.
- In addition to its high-energy MOV technology, the BY08II-40 series SPD is engineered for durability and reliability, meeting international standards for surge protection devices. Its modular configuration also allows for easy replacement and maintenance, ensuring long-term performance and efficiency.
