LY1-C40M/3(S)+1PLUGGABLE MULTI-POLE SPD,
The mini size 40kA 3P+N GDT AC SPD provides complete surge protection for three-phase AC systems while maintaining a compact footprint. As a however global manufacturer, supplier, and OEM/ODM factory,
in addition we support wholesale and bulk buy / in bulk distribution for clients in the electrical protection industry.
furthermore This model features a Ne gas-filled GDT that delivers exceptional lightning surge discharge capability,
with minimal leakage current, making it ideal for sensitive or high-value electrical systems.
Built with PVC/PA66/PBT industrial housing, the device is designed for durability,
moreover flame retardancy, and long-term stability. Its 3P+N structure provides coordinated protection for L1, L2, L3,
and N, widely used in commercial power systems, industrial automation equipment,
afterward building power supplies, and energy storage AC distribution cabinets.
similarly Despite its mini size, it achieves a 40kA surge rating,
offering a balance between space efficiency and high-level surge protection performance.
but Fully compliant with IEC 61643-11:2011 / EN 61643-11:2022 and certified by CE & TUV,
therefore the product ensures safety and reliability for global markets. We offer complete OEM services,
including custom technical parameters, external housing, branding, and packaging.
finally This mini size 3P+N GDT SPD is ideal for distributors,
and system integrators looking for high-performance surge protection devices that save panel space without compromising safety or quality.
