- Three phase to cater for 5 KW load in each phase in three different directions.
- Two phase to cater for 5 KW load in the two different direction.
- Single phase to cater for 2 K load in one direction.
However it is always advisable to load the switch up to 80% load capacity, as a safety measure connections of all three are shown below separately.
