Yep, you are right, possible relays, not parts ( for me full relay is spare parts too)
Q., how relays, for extreme cases, whole range is difficult and not so cheaper.
RE: Spare parts for a digital protective relays
Some plants try to standardize as much as possible, even that means applying a relay that has many more functions than will be used for a particular application. Such as using a Multilin SR-750 or SEL-351 for all overcurrent relaying applications, although they are overkill for many of the applications. This has a lot of advantages that can make up for the added cost of the relay.

Good points.
Next point, one relay ( each type) per SS, power plant or per 100 relays of same type?

Spare relays for most used applications.
