Whether you’re operating within IT, TT, TN-C, TN-S, or TN-CS systems, the MLY1-100 provides robust protection against indirect and direct lightning strikes and other transient overvoltage surges. Compliant with the IEC61643-1:1998-02 Class II surge protective device standard, the MLY1-100 is a reliable choice for ensuring the longevity and safety of your electrical equipment. This device, compliant with the GB 18802.1/IEC61643-1 standard, meets the highest industry standards for performance and reliability, ensuring you can count on it.
The MLY1-100 utilizes a Class B surge protective device (SPD), providing comprehensive protection through both common-mode (MC) and differential-mode (MD) mechanisms. In a typical three-phase, four-wire system, the MLY1-100 is strategically installed between the three phases, neutral, and ground. Under normal operating conditions, the device maintains a high-impedance state, enabling seamless power distribution. However, if a surge voltage, caused by lightning or other disturbances, occurs, the MLY1-100 responds with incredible speed, activating within nanoseconds. This rapid response safely directs the surge voltage to ground, effectively protecting your electrical equipment from potential damage.
The MLY1-100 is easy to install and use, requiring no adjustments after installation. Once properly installed, it automatically activates and protects your grid without any additional intervention. Regular maintenance is recommended to ensure optimal performance; users should regularly inspect the module for any signs of faults. A fault indicator provides a clear visual indication, changing from green to red when a component requires replacement. Promptly resolving issues maintains the integrity of the power distribution system and ensures continued protection of your valuable power assets. With the MLY1-100 surge protector, you can rest assured that your system is protected from unpredictable natural disasters.
