supplied with the breaker for pin-out assignments.
(6) The assignments for pins B3 - B6 will differ depending on whether the DESP option has been supplied. See
the MPSC-2000 schematic supplied with the breaker.
Notes:
(1) These assignments are
provided for reference only,
and may be changed due to
special requirements. Some
pins or plugs may not be
present on all breaker
configurations. See the
breaker schematic wiring
diagram(s) for details.
(2) Note the polarity of control
devices: “+” is the send and
“-” is the return.
(3) The two terminals of each
Auxiliary Switch contact are
connected to adjacent
Secondary Disconnect pins.
For example, pins A14 and
A15 are connected to a
single “a” contact. Also, the
polarity signs are provided
on these pins for consistency
only; the Auxiliary Switch
contacts are not polarity
sensitive.
(4) The Alarm Switches can be
wired in two different ways.
See the schematic supplied
with the breaker for details
on the pin-outs.
(5) The pins marked “(Spare)”
may be used in some
b r e a k e r s f o r s p e c i a l
c u s t o m e r w i r i n g
requirements. Refer to the
schematic wiring diagram
