Like the main contacts, the auxiliary contacts can be easily varied to meet most requirements. Four types of auxiliary contacts are available :

- Type P :instantaneous single contact, mounted on the axies, with adjustable contact gap and pressure and with contact elements in silver: N/O (normally open), N/C (normally closed) and C/O (changeover) executions are available;
- Type B : set of 10 instantaneous contacts (5N/O + 5N/C), double interruption moulded type, mounted together on a single frame and simultaneously controlled. Each set type B takes the same space as two type P contacts.

All the contactors of the sizes 270A and larger can be fitted with auxiliary poles rating 46A or 60A with or without magnetic blow-outs and N/O or N/C type.
