The overall dimensions given in the next pages refer to standard contactors up to 3000A and 1000V.
For higher ratings in current, as well as in voltage or special executions, please ask our Technical Departement.
The length of the contactors, i.e. the distance between fastening bolts, depends upon the composition of the unit as follows :

- Number of poles: 1 - 2 - 3 or 4 poles;
- Control circuit in A.C. or D.C.: the contactors of size over the N350 are always fitted with D.C. coils; if A.C. control is required, a selfcontained rectifier unit is available;
- Number and type of auxiliary contacts: as already described four types of auxiliary contacts are available;
- Type P : single contact adjustable N/O, N/C or C/O.
- Type B : set of 5 N/O + 5 N/C contacts.

The minimum clearance Bm between two contactors mounted one or above the other corresponds to the clerance neccessary for mechanical interlocking. The distance Is is the minimum clearance between the contactor and an earthed frame. (See drawings in the next pages).
