Class C Power Surge Protector LP-20C

Model LP-20C

LP-20C plug-in surge protector for power class C, protecting low-voltage distribution boxes against overvoltage from lightning strikes or mis-operation, with 20 kA nominal and 40 kA maximum discharge current and a green/red status window.

Overview

About the Class C Power Surge Protector LP-20C.

The LP-20C is a plug-in lightning and surge protector unit designed for power class C. Installed in a building's low-voltage distribution box, it protects the connected supply against overvoltage caused by lightning strikes or switching mis-operation, limiting the voltage that reaches downstream equipment. The protection module plugs into its base, so a failed module can be replaced without rewiring the live conductors. A status window shows green when the module is healthy and red when it has failed, and modules can be combined for single-phase or three-phase systems.

Features

  • Plug-in module design for live-wire replacement
  • Built-in temperature control and circuit-breaking technology
  • Green window indicates normal; red indicates failure
  • Optional tele-signalisation interface for remote monitoring
  • Modules combine as 1P, 2P, 3P, 4P, 1P+NPE and 3P+NPE
  • Four voltage versions: Uc 75, 275, 385 or 690 V AC
  • Flame-retardant reinforced nylon housing (UL94 V-0)

Applications

  • Power class C surge protection
  • Building low-voltage distribution boxes
