The various protective functions available on a given relay are denoted by standard ANSI device numbers. For example, a relay including function 51 would be a timed overcurrent protective relay. An overcurrent relay is a type of protective relay which operates when the load current exceeds a pickup value. It is of two types: instantaneous over current (IOC) relay and definite time overcurrent (DTOC) relay.
Depends on the kind of relay, as to signal sent to a cb. Undervoltage, over current, etc. Protection relays close/trip circuit breaker coordination.
