Introduction
Auxiliary Switch:
Auxiliary contacts indicate the position of the
Circuit Breaker main contacts. These contacts
operate simultaneously with the breakers main
contacts. Default breaker configuration consists
of 3 normally open (NO) and 3 normally closed
(NC) contacts. The STD Auxiliary switch (GAUX3R)
can be replaced with any of the following
configurations to increase the number of
available contacts.
• Power rated contacts 8 NO & 8 NC
(GAUX6R)
• Power rated contacts 3 NO & 3 NC plus
Low Signal rated contacts 2 NO & 2 NC
(GAUX5R)
• Power rated contacts 4 NO & 4 NC plus
Low Signal rated contacts 4 NO & 4 NC
(GAUX8R)
