The MLY1-A25-50B Lightning Surge Protector (SPD), a cutting-edge solution designed to safeguard your electrical systems from the unpredictable forces of nature.

With the increasing frequency of lightning strikes and transient overvoltages, ensuring the protection of your power supply systems has never been more critical. The MLY1-A25-50B is specifically engineered for AC 50/60Hz, 380V power supply systems, making it an ideal choice for TT, TN, and other configurations. This SPD is particularly suited for areas with a high risk of lightning, providing primary (Class B) lightning protection to keep your electrical infrastructure safe and operational.

The MLY1-A25-50B is built to meet and exceed the stringent requirements outlined in the current national standards, including GB50057-2010 and GB 18802.1. This single-port, indoor fixed-mount voltage-switch SPD boasts impressive technical specifications, including a high impulse current rating of 30kA and a low residual voltage of just 2.5kV. At the heart of this advanced surge protector is a multi-stage graphite gap, which ensures optimal performance during surge events. The thoughtful design and precise machining of the MLY1-A25-50B create a sealed structure that effectively prevents arc leakage, even under the most demanding conditions. This means you can trust that your electrical systems will remain protected, allowing for uninterrupted operation.

Installation of the MLY1-A25-50B is straightforward and user-friendly. It is designed to be mounted on a standard 35mm DIN rail, making it compatible with most distribution boxes and cabinets. The connecting wires can accommodate stranded copper wire sizes ranging from 6-35mm², while the grounding wire should be a two-color conductor of 16mm² or larger, with a maximum length of 500mm. To ensure the longevity and reliability of the surge protector, it is recommended to connect the protector on the L line in series with a fuse or circuit breaker, selected according to the nominal current In. By following these installation guidelines, you can ensure that the MLY1-A25-50B operates effectively, providing peace of mind and protection for your valuable electrical systems.

In summary, the MLY1-A25-50B Lightning Surge Protector is an essential component for anyone looking to enhance the safety and reliability of their electrical infrastructure. With its robust design, compliance with national standards, and ease of installation, this SPD is the perfect choice for protecting against lightning strikes and transient overvoltages. Invest in the MLY1-A25-50B today and experience the confidence that comes with knowing your power supply systems are well-protected against the elements.
