ID Name |
Uniquely identifies the equipment item. The program automatically assigns a name, but you can change it, if needed. The name can be up to 16 characters long. For relays, the program automatically assigns the names R-1, R-2, R-3, and so on. |
Group Name/Type | If the relay is part of a functional group, the group name and type appears here. See Functional Groups. |

Figure 4: Relay Data - Settings Dialog Box
Some relays have settings and time current curves just like the low voltage breaker solid state trip devices. The common type is direct action trip (DAT) units found in some medium voltage breakers. The settings tab for these relays has a slightly different layout as described below.
