One of fourteen
Į
xed
Ɵ
me bands can be selected. The
Į
xed
delay bands are listed in Table 2.8. The bands and slopes are
depicted as Time Current Diagram in appendix 6.1 of this
Applica
Ɵ
on manual.
The Mpro N type Trip Unit can op
Ɵ
onally be equipped with a
system that allows full selec
Ɵ
vity independent of the chosen
breaker se
ƫ
ngs. (ZSI)
Zone-selec
Ɵ
ve interlocking coordinates breakers so that the
downstream breaker is allowed the
Į
rst opportunity to clear a
fault or overload event. ZSI interlocks & coordinates reac
Ɵ
ons to
a fault on the short-
Ɵ
me (ST), instantaneous (I), and
ground faults (GF) devices.
The Zone Select Interlock (ZSI) func
Ɵ
on operates with a group of
series-connected breakers and can only be used when a +24VDC
auxiliary power supply is available.
In cases when more than 4 outgoing breakers need to be
coordinated with one or more mains or incoming breakers the
use of a interconnec
Ɵ
on device or mul
Ɵ
plier is strongly
recommended. The AEG TIM device (Catalogue number
--TIM1--) can be used for these kind of applica
Ɵ
ons. This device
also requires a +24VDC control voltage power supply.
When a ZSI input is received an upstream breaker will not use
the standard ST ZSI and/or GF ZSI delay band and slope se
ƫ
ng.
It will automa
Ɵ
cally use a 2nd set of se
ƫ
ngs that the user can
individually set for use when ZSI is ON. When the ZSI input is
cancelled the breaker will revert to it's standard se
