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
