Size 0-2 Max three poles - 4 single circuit auxiliary contacts (NO or NC)*
Size 0-2 Max three poles - 2 single circuit auxiliary contacts (NO or NC) plus one power pole adder
Size 0-2 four or five poles - 2 single circuit auxiliary contacts (NO or NC)
Size 3-4 two to five poles - 3 single circuit auxiliary contacts (NO or NC)
Size 5 two or three poles - 2 single circuit auxiliary contacts (NO or NC) plus one power pole adder
Size 6-7 two or three poles - 3 single circuit auxiliary contacts (NO or NC)
Size 6-7 two or three poles - 2 single circuit auxiliary contacts (NO or NC) plus one power pole adder
*when adding 4 external auxiliary contacts to one size 0 or 1 contactor, remove one of the return springs
See part number table below for selection:
* - Types SX9 and SX10 or types SX16 and SX17 must be used together and mounted on the same side of the contactor. They are suitable for applications where it is necessary for a normally open contact to overlap a normally closed contact.
# - Types SX11 and SX12 are not for use on NEMA size 3 or larger. Internal contacts can also be used on Class 2510 types M and T manual starters
