The MLY1-C40/385 surge protective device (SPD), an advanced solution designed to protect low-voltage AC power distribution systems.

Whether you operate within an IT, TT, TN-C, or TN-CS power supply framework, this Class II surge protective device provides robust protection against indirect and direct lightning strikes and other transient overvoltage surges. Compliant with IEC61643-1:1998-02, the MLY1-C40/385 series ensures your electrical system remains safe even during unpredictable electrical disturbances.

The MLY1-C40/385 surge protector (SPD) features dual protection modes, providing both common-mode (MC) and differential-mode (MD) protection. This versatility makes it ideal for a variety of applications, including floor distribution boxes, computer centers, telecommunications rooms, elevator control rooms, cable TV rooms, fire stations, villas, and residential distribution boxes. Designed for fixed indoor installation, the device features a built-in circuit breaker that automatically disconnects the SPD from the grid in the event of overheating or a fault. This feature not only enhances safety but also provides a clear visual indication of the device’s operating status: green for normal operation and red for disconnection due to a fault.

The MLY1-C40/385 surge protector (SPD) is easy to install using a standard 35mm DIN rail and accommodates stranded copper conductors with diameters ranging from 2.5 to 35mm square. Each pole of the SPD must be equipped with a fuse or miniature circuit breaker to ensure lightning current protection and short-circuit protection after an SPD failure. With its reliable performance and user-friendly design, the MLY1-C40/385 surge protector is an ideal choice for anyone looking to strengthen their electrical system’s resistance to surges and spikes. The MLY1-C40/385 surge protector protects your investment and ensures the longevity of your equipment.
