There are only 4 poles in the contactor, with one pole for each circuit. There are 7 off peak circuits (that I can see). Hence the 3 individual relays, one each for the other 3 circuits. There were probably originally 7 of the relays, or 2 of the 4 pole contactors.
You can think of a contactor as a relay with the ability to switch higher current loads.
