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.
Model: 1 : Maximum Leakage Current 2 : Protection Level
Model: 1 : Protection Level (B+C, C) 2 : Numbers of Module Combination (1 - 4) 3 : Equipotential isolation protection device: NPE or monitoring warning device FS, AS. In order to be compatible with power automation, precision controls, remote controls and electrical system monitoring, a great deal of electronic devices are now being installed indoors. Surge, which may be caused by lighting, lightning strike, circuit breakdown or on-off operations may easily damage equipment or even threaten personal safety. To prevent surge damage, surge protection devices are installed. WII surge protection device (SPD) can be divided into two categories; module combination type providing lightning warning and remote monitoring control devices with alarms; and integrally molded type, which are designed to release intense current. Our metal oxide varistor (MOV) and the anti-fire enclosure of the module combination type are UL approved and certified. The enclosure of the integrally molded type is made of self-extinguishing resin, which enhances its safety.
