About the Product
Surge Protection Devices (SPD)
From the need to automatize as well as remotely, precisely control and monitor an electrical power system, the use of a large amount of electronic equipment is resulted. However, a high-voltage surge induced by lightning discharge current, as well as a surge caused by a line fault or the operation of a switch, may easily damage expensive equipment or even threaten the safety of personnel. With a view to averting the aforementioned surge-related dangers, a carefully-designed low-voltage power system and its appropriate placement, combined with installation of a correct surge protection device, are necessary means for preventing serious harm.
WSP-B+C Modular Surge Protection Device for Low-Voltage Power Systems
