Rockwell Automation 140U Q, M Frame CB Alarm Switch and Auxiliary Switch Combination - Manual (Page 2)

SPDT switch is closed and the “b” contact is open.
When the crossbar is in the tripped or contacts-open
position, the “a” contact is open and the “b” contact is
closed.
Table 1.1 lists electrical rating data for the auxiliary
switch.
For this publication, the term circuit breaker shall also
include molded case switch and motor circuit protector.
Depending on the model ordered, connections for the
ASL switch and auxiliary switch contacts are in one of
four forms. The standard wiring configuration is pigtail
leads exiting the rear of the base directly behind the
accessory, leads exiting the side of the base where the
accessory is mounted, and leads exiting the rear of the
base on the side opposite the accessory. The 18-inch
long pigtail leads are color coded for identification; iden-
tification labels are provided for pigtail leads and termi-
nal block points. For allowable locations of all acces-
sories, refer to Selection Guide.
No more than three pigtail leads can be routed
through the rear trough in the circuit breaker base.
When the walking beam interlock is used with the
circuit breaker, the rear trough cannot be used for
accessory pigtail leads.
This instruction leaflet (IL) gives detailed procedures for
installing the ASL switch and ASL switch/auxiliary switch
combination (accessory combination).

2.0 INSTALLATION
The ASL switch(es) accessory combination can be
field-installed in circuit breakers
Q and M-Frame.
NOTICE
NOTICE
NOTICE
Where local codes and standards permit and UL list-
ing is not required, internal accessories can be field
installed in sealed circuit breakers. In this case, UL
listing becomes invalid and the label should be
removed.
Before attempting to install the ASL switch or
accessory combination, check that the catalog num-
ber is correct as ordered and that the rating of the
accessory(s) satisfies the job requirements.
The ASL switch (shown in kit form in Figure 2-1) and
accessory combination, is installed in the right or left
accessory mounting cavity of a 2-, 3-, or 4-pole circuit
breaker with a fixed thermal, adjustable thermal or
electronic trip unit. An auxiliary switch must be installed
in the circuit breaker before the circuit breaker is mounted
in an electrical system. To install the auxiliary switch,
perform the following procedures:
A circuit breaker that is mounted in an electrical
system must be removed to install the accessory.
To ensure correct accessory installation, the circuit
breaker must be placed on a horizontal surface.
