The relay includes the following options fo

Local tripping and closing, via relay opto-isolated inputs
•
Remote tripping and closing, using the relay communications
It is recommended that separate relay output contacts are allocated for remote circuit
breaker control and protection tripping. This enables the control outputs to be selected via a
local/remote selector switch as shown in Figure 13
