B+C Modular Surge Protection Device for Low-Voltage Power Systems

WSP-B+C

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

  • Application: For buildings with an overhead power source or those with a lightning protection device.
  • Protective Elements: Nonlinear zinc oxide varistor and thermal stripper.
  • Structure: Quick plug-in design with base.
  • Fault Indication: Fault Indicator Window.
  • DIN Rail: 35mm.
  • Other Features: With a choice of optional, modular monitors: FS Monitor (sound and light alarms) or AS Monitor (remote alarm).
