Both switching contacts are designed as potential-free and 'Normaly Open'. The relays are 'Bistable', which means that when they are switched on via the app, the coil does not have to remain constantly drawn, which significantly reduces heat development in the device when switched on for a long time. The contacts can withstand high short-term inrush currents.

Attention; the contacts are allowed with maximum 5A per contact be taxed, even if you see different information elsewhere!
