Shop for AC surge protective device LY1-C40M/1(S)+1Pluggable single-Pole SPD

AC surge protective device LY1-C40M/1(S)+1Pluggable single-Pole SPD,

Our mini size 40kA 1P+N GDT AC surge protective device is specially engineered for single-phase systems that require a coordinated protection structure. As a professional manufacturer, factory, and OEM/ODM supplier, we support wholesale, in bulk, and bulk buy orders for global clients demanding reliable power protection components. This P+N design integrates a GDT surge module (Ne gas) working together with optimized protective circuitry to provide high protective performance against lightning and transient overvoltage.

Made with durable PVC/PA66/PBT housing, the device offers excellent insulation, heat resistance, and mechanical strength, making it suitable for large-scale deployment in residential buildings, commercial facilities, and industrial power distribution cabinets. The mini size format allows installation in compact systems while still delivering a high surge capacity of 40kA, ensuring robust protection for AC circuits and connected loads.

Designed for 35mm DIN-rail installation, it is ideal for small control panels, solar AC output protection, UPS input/output, energy storage systems, and modular distribution boards. It adheres to IEC 61643-11:2011 / EN 61643-11:2022 safety standards and is certified with CE & TUV, ensuring reliability for international markets. As a wholesale-oriented factory, we offer full OEM customization, including label printing, housing design, and circuit tuning. This mini size P+N GDT SPD is the perfect choice for distributors seeking compact, efficient, and factory-direct surge protection solutions.
