Product Description
The MYS8-385/40-4P series is a modular surge protective device (SPD) designed for TN-S power distribution systems, featuring a "4+0" circuit configuration. Compliant with EN 61643-11 (Type 2) and IEC 61643-11 (Class II), it provides reliable protection against transient overvoltages caused by lightning strikes and switching operations.
The device delivers a high nominal discharge current (8/20μs) of 40kA and a maximum discharge current of 60kA, with a voltage protection level (Up) of ≤2.4kV and a fast response time of ≤25ns (L-N), ensuring effective clamping of surge events. It operates at an AC nominal voltage of 230/400V (50/60Hz) with a maximum continuous operating voltage (Uc) of 385V (50/60Hz), making it suitable for demanding industrial and commercial applications.
The SPD features a clear green/red status and fault indication window for easy visual monitoring. Installation is quick and tool-friendly, thanks to the 35mm DIN rail mounting per EN 60715 and screw terminals (M5, 3.0Nm ±10%) accommodating conductor cross-sections from 1.5mm² to 35mm² stranded / 25mm² flexible wire. The thermoplastic housing (UL 94 V-0) provides IP20 protection and is suitable for indoor installation. The product is available in 1P, 2P, 3P and 4P configurations to suit various system requirements.
The (S) variant additionally provides a floating changeover remote signaling contact (125VAC/1A, 30VDC/0.5A) with a 0.2mm² terminal cross-section and M2/0.25Nm screw torque, enabling remote monitoring of the SPD status for integration into building management or SCADA systems.
With an operating temperature range of -40℃ to +70℃, the MYS8-385/40-4P series is an ideal choice for reliable, maintenance-friendly surge protection in TN-S electrical installations.
