Whether you are operating within IT, TT, TN-C, or TN-CS power supply frameworks, this Class II surge protective device is engineered to provide robust protection against both indirect and direct lightning strikes, as well as other transient overvoltage surges. Compliant with the IEC61643-1:1998-02 standard, the MLY1-C40/385 series ensures that your electrical systems remain safe and operational, even in the face of unpredictable electrical disturbances.
The MLY1-C40/385 SPD features a dual protection mode, offering both common-mode (MC) and differential-mode (MD) protection. This versatility makes it an ideal choice 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. The device is designed for indoor fixed installation and is equipped with a built-in disconnector that automatically disconnects the SPD from the power grid in the event of overheating or breakdown. This feature not only enhances safety but also provides a clear visual indication of the device’s operational status, with a green light signaling normal operation and a red light indicating disconnection due to failure.
Installation of the MLY1-C40/385 SPD is straightforward, utilizing a standard 35mm rail for mounting and accommodating copper multi-strand conductors with diameters ranging from 2.5 to 35mm². Each pole of the SPD must be protected by a fuse or miniature circuit breaker to ensure lightning current protection and short-circuit safety after SPD breakdown. With its reliable performance and user-friendly design, the MLY1-C40/385 surge protector is the ideal choice for anyone looking to enhance the resilience of their electrical systems against surges and spikes. Protect your investments and ensure the longevity of your equipment with the MLY1-C40/385 Surge Protective Device.
