Product description
The MYS11-385/100-4P (S) is a high-discharge-capacity modular surge protective device (SPD) designed for TN-S power distribution systems. It adopts a "4+0" full-mode protection circuit and is suitable for second-level lightning and switching overvoltage protection in low-voltage building distribution systems.
The product is designed in accordance with EN 61643-11 and IEC 61643-11 standards and belongs to the T2/Class II test classification. Its core performance combines high discharge capability with low residual voltage: the nominal discharge current (In) reaches 100kA (8/20μs), and the maximum discharge current (Imax) can reach 150kA, enabling it to effectively divert the enormous surge currents generated by lightning strikes or power grid switching operations. At the same time, the voltage protection level (Up) is kept at ≤3kV with a response time of ≤25ns, ensuring that downstream sensitive equipment is protected from transient overvoltage surges.
In terms of structure and functional design, the series features a thermoplastic flame-retardant housing (UL 94 V-0) for 35mm DIN rail mounting, with a degree of protection of IP20, making it suitable for indoor distribution cabinet environments. The product is equipped with a green/red dual-color operating status indicator window, allowing maintenance personnel to visually assess the health status of the SPD. The model suffix "(S)" version additionally integrates a remote signaling function, providing a floating changeover contact (125VAC/1A or 30VDC/0.5A) that can transmit fault signals remotely to a monitoring system, meeting the requirements of intelligent distribution operation and maintenance. The product is available in multiple pole configurations from 1P to 4P, with the 4P model specifically optimized for comprehensive protection of phase lines and the neutral line to the PE line in TN-S systems.
