Section 1: General information
The optional pop-out mechanical trip indicator, located to the right of
the trip unit on the breaker’s front faceplate, operates by releasing and
popping out any time the breaker trips due to an overcurrent condition
(Figure 1). Three versions of the pop-out trip indicator are available:
Version 1: The non-interlocking indicator will not prevent the breaker
from being reclosed. The indicator is reset manually by pushing it back
in.
Version 2: The interlocking pop-out indicator must be pushed in and
reset before the breaker can be reclosed.
Version 3: The remote reset interlocking pop-out indicator may be
reset manually or remotely.
When resetting any version, ensure that the button is fully reset to a
hard stop.
An optional overcurrent trip switch (bell alarm) can be used in
conjunction with either mechanical trip indicator. The overcurrent trip
switch operates off the position of the mechanical trip indicator, and is
reset when the indicator is reset.

Become familiar with the pop-out trip indicator being used. Figure 2
illustrates the non-interlocking indicator version and Figure 3 illustrates
the interlocking indicator version. Both indicators look very similar
externally. The only noticeable difference between the two is a small
molded hook-shaped device on the interlocking indicator version. This
hook operates the interlocking feature. Both indicators are, however,
installed and removed in the same way.
