A 2-pole AC SPD (Surge Protection Device) is a single-phase electrical component for protecting appliances from voltage spikes, featuring two poles (live and neutral) for a single-phase circuit, DIN-rail mountable, with fast response times (<25ns) and visual indicators (green for normal, red for fault) to guard against lightning or power grid issues, requiring proper earthing for effective operation.
How it Works
- Detects Surge: When a voltage spike occurs, the SPD activates.
- Diverts Energy: It channels the excess current safely to the ground (earth wire).
- Indicates Status: The indicator window changes color, signaling if it’s working or needs replacement.
