Signal output contacts

Signal output contacts are single-pole, single (normally open/form A or change-over/
form C) signal output contacts (SO1, SO2, ...) or parallel connected dual contacts.
The signal output contacts are used for energizing, for example, external low burden
trip relays, auxiliary relays, annunciators and LEDs.
