I’m urgently asking about some questions regarding the power of solenoid valves! !

As the title suggests, a relay for solenoid valves is to be designed for users, with a total of 170 DO points. The solenoid valve is 220vAC. How many 10A circuit breakers do I need at minimum to power it and ensure the load is satisfied? Thank you; my question might be a bit amateurish, but I hope to understand it.

Typical solenoid coil powers are 6W, 8W, and 10W. Assuming 10W per unit, 170 units would amount to 1700W. The current required is 1.7×5=8.5A; one such unit is sufficient, as 10A is also adequate
