BY08 1+2-7 SPD Class T1+T2 Imax 50KA Surge Protective Device
product detail
Product Overview
- The BY08 1+2-7 Series T1+T2 AC SPD Surge Protective Device is a high-performance surge protection device designed to protect electrical systems from transient overvoltages and power surges. Utilizing high-energy MOV (Metal Oxide Varistor) technology, this surge protector effectively absorbs and dissipates surge energy, providing robust protection for sensitive electrical equipment.
- This series offers flexible configurations, including 1P, 2P, 3P, 4P, 1P+NPE, and 3P+NPE, ensuring compatibility with a wide range of electrical systems. It supports various operating voltages, including 150V, 275V, 320V, 385V, and 440V, making it suitable for use in both low-voltage and higher-voltage applications.
- The BY08 1+2-7 series SPD is designed to handle high discharge currents ranging from 25kA to 50kA. This allows the device to withstand significant surge energy, such as that generated by lightning strikes or power grid fluctuations, while protecting critical equipment from potential damage. Its high discharge capacity ensures reliable operation and reduces the risk of downtime or costly repairs.
- An important feature of the BY08 1+2-7 series SPD is its modular design. The device includes replaceable modules, enabling quick and easy maintenance. If a module is damaged due to a surge, it can be replaced without needing to replace the entire unit, making the surge protector cost-effective and convenient for long-term use.
- In addition to its durability and performance, the BY08 1+2-7 series SPD is easy to install and integrates seamlessly into existing electrical systems. It is ideal for protecting power distribution boards, industrial control systems, telecommunications equipment, and other sensitive devices from harmful power surges.
