28 S&C Instruction Sheet 695-535
Programming the Overcurrent Protection Settings
Each overcurrent control is capable of operating up to two fault interrupters.
To differentiate between the two fault interrupters, they are called Interrupter 1 and
Interrupter 2 in this instruction sheet, though they will be renamed at the factory accord-
ing to their “Way” designation. These interrupters may be renamed by the user. See the
“Changing the Interrupter ID” section on page 23.
On switchgear with only one fault-interrupting way, only Interrupter 1 is used in the
control. On switchgear with more than two fault-interrupting ways, there will be more
than one overcurrent control. The fault interrupters controlled by the overcurrent control
will be named according to their “Way” designation and will be clearly labeled on the
outside of the overcurrent control enclosure.
The Interrupter 1 and Interrupter 2 menus allow the user to change the protective
settings for the selected fault interrupter. See Figure 21.
