Mechanical characteristics

The PRO-N protection relays are housed inside metal cases suitable for various kinds of assembly:
- flush mounting
- projecting mounting
- with separate operator panel
- rack.
The solution with projecting assembly and a separate operator panel is particularly suitable for limited in depth installations. The connections to the current signal inputs can be made by ring lugs and an insulating panel covering the terminals may be mounted for safety purposes. Removability is ensured to facilitate maintenance operations so that the electronic module can be replaced; this provides minimum downtime and maximum protection availability.
