Moin,
I hope this is a suitable group for this kind of question. If no, suggestions are welcome.
I'd like to automate our storage/tank water heater using some home automation system using zWave.
Local power is 240V 50Hz
The Water Heater is rated 220V-240V 2.5-3kW
(which in my calculations may end up just above 13A)
Originally, the water header was just connected directly to the incoming power supply via a 2-throw wall switch (for both the L and N wires, ground connected through inside the switch housing.
I was planning to use a Fibaro FGS-213 switch for this
It is rated at 8A tops, so it cannot be used with the heater as load directly
So I got a contactor:
Schneider TeSys LC1K09 10M7
which is rated:
| [Ie] rated operational current | 9 A AC AC-3 for power circuit at
