ANSI C136.41/NEMA 7 PIN Surge Protection Devices, Fast Plugin Surge Module from LONG-JOIN Brand

Why do we develop a surge protection module?  this JL-250F receptacle with a Surge protective device, then it is ideal for city traffic systems, municipalities, and Utilities and prevents overload voltage or overload current at sudden lightning issues or power-related problems of evil environments. additionally, you can any time to replace the light photo control, especially on the street lights, which are needed for maintenance the whole year. The product has built-in surge differential mode + surge common mode protection, which greatly improves the working ability of the light controller in a complex electromagnetic interference environment. Feature 1-merely opeating voltage, SPD module work voltage parameter changaable; 2-this spd module is located in differnet position. this module above NEAM base, and below light controller with 120-277VAC; 3-contrast competitor similar surge protetion module, our SPD module design structure prospects combine Human mechanical handshake design, more convenient rotation, and its inner space build setting safe and reliable central ground current hole design to assure light controller better safely steady work avoid direct damage effective from light fixture external strict weather condition. 4-fast plug-in surge module any time.
