Products with part numbers CA3KN or CA2KN are control relays form the TeSys K range with 4 contacts. Schneider Electric also offers the smaller CA2SK or CA3SK with just 2 contacts.
The K relay has 4 auxiliary contacts, 3 versions are available;
- 4 N/O and zero N/C
- 3 N/O and 1 N/C
- 2 N/O and 2 N/C
The generic part number format for the K relay is; CAuKNvwxy, where:
u = 2, AC control coil
u = 3, DC control coil
v = number of N/O contacts
w = number of N/C contacts
The last two digits, xy, indicate the control coil voltage: for example; BD =24 Vdc, P7 = 230 Vac
The SK relay has 2 auxiliary contacts, 2 versions are available;
- 2 N/O and zero N/C
- 1 N/O and 1 N/C
The generic part number format for the SK relay is; CAuSKvwxy, where:
u = 2, AC control coil
u = 3, DC control coil
v = number of N/O contacts
w = number of N/C contacts
The last two digits, xy, indicate the control coil voltage: for example; BD =24 Vdc, P7 = 230 Vac
Note: It is possible to add additional contacts to both the K and the SK relays
