* three power output contacts PO1. PO2 and PO3

* two signal output contacts SO1 and SO2

Switch group SGR1…. .8 is used to route internal signals from the protection stage, external trip signals and signals from the automatic reclosing function to the required signal or power output contacts.

The minimum pulse length can be configured as 40 or 80 ms and the power output contacts can be configured as latching.
