Description
Type DSL4 control relays are compact con­
trol relays ideally suited for applications
where size is a factor. They are available
with either screw terminals or quick connect
%" push on spade terminals. All terminals
are accessible from the front and the screw
terminals are positioned for straight through
wiring. Relays mount conveniently on stan­
dard DIN 35mm mounting rails or may be
panel mounted via integral mounting feet.
Description
Type DSL9 control relays are Ac-actuated,
type DGSL9 Dc-actuated, control relays for
applications up to 600 volts Ac or 300 volts
Dc. Captive screw terminals are front acces­
sible and positioned for straight through
wiring. Relays mount on standard DIN
35mm mounting rails or may be panel
mounted via integral mounting feet.

Complete system flexibility is achieved by
the addition of 2 or 4-pole auxiliary contact
blocks and pneumatic timing blocks. These
auxiliaries simply slide on both DSL9 and
DGSL9 control relays to provide 6 or 8-pole
relay versions as well as on-delay or off­
delay timing relays with timing ranges avail­
able from .1 to 180 seconds.

Utilization Categories
All Westinghouse IEC contactors are tested
for the most severe switching conditions of
utilization category AC-4. The rated making
and breaking capacities lie above those
shown in the table for "Occasional duty".
ua
ls
The applications and duty cycles of contac­
tors are indicated by utilization categories
together with details of rated operating cur­
rent or motor rating and rated voltage. Utili­
zation categories are listed in the table
below. To classify the contactor, the operat­
ing conditions must be known. The table
then assists in practical contactor selection.

Contact Life for Contactors
lec
The following data is needed for proper selection of a contactor:
Load rating
Service and control voltage, frequency
Utilization category
Switching frequency per hour
Required contact life
.E
In practice, contactors are used for various utilization categories (see table below). This
leads to varying wear of the silver present on the contacts when switching. Contactors of
modern design have a contact life which is generally sufficient for the application. If a
rough check of the contact life to be expected is necessary for particular applications, the
following tables and curves show the typical and characteristic data for the contactors to
utilization categories AC-l, AC-3 and AC-4.

Contact Life for Utilization Category AC·1
Purely-resistive or slightly-inductive loads fall into this Utilization Category.
Typical applications are: Electric space heating, dryers, water heaters, warm-beverage
vending machines, cleaning apparatus, industrial ironing appliances, etc.

For motors operated per utilization category
AC-3, contactors are usually selected from
motor rating and service voltage. The con­
tact life is determined by the volume of sil­
ver on the contacts and lies in the region of
1 million switching cycles for contactors

Example
Assume a contactor is required to control a 10 HP motor at 460 volts in AC-3. Several
options are available. If one million operations is sufficient, a DSL9 contactor will suffice.
However, if longer contact life is needed, the curves predict contact life controlling a 10 HP
motor as follows:
ww
w
.E
lec
tri
It is not appropriate to extrapolate the curves to values less than 1 million operations to
obtain higher HP ratings with lesser contact life. No contactor should be applied above its
kW rating because the locked rotor and thermal capability of the contactor must be consid­
ered, and there may be problems of attaching the larger conductors required for a higher
rating.

Applications: Motors on manufacturing and
processing machines where inching or plug­

machinery or tapping operations. Pure AC-4
operation is seldom encountered. In most
cases, there is a mixture of AC-3/AC-4 oper­
ation. The contact life for mixed operation
can be calculated using the formula at the
bottom of this page.

Contact Life for Mixed AC-3/AC-4 Applications
ca
Almost all applications for motor contactors do not fall completely into utilization category
AC-3 or AC-4 but are a mixture of AC-3 and AC-4 operations.
This includes, for example, the use of contactors to jog manufacturing and processing
machinery, electric hoists, winders, mixers, cranes, conveyors during machine-setup as
well as occasional plugging-operations.

•
Contactor DSL 32 with contact life

Contactor DSL 44 with contact life of about
switching cycles.

Example
A
HP,
V,
Hz motor is switched by
a reversing contactor. The operating con­
ditions fall into utilization category AC-4 be­
cause the fast change in direction of
rotation means that currents greater than
the motor-starting current must be switched
off. Which contactor is suitable?
100,000
Contactor DSL 32 with contact life
switching cycles .
Contactor DSL 44 with contact life of
about
switching cycles.
270,000
It can be decided from the "Table to deter­
mine number of switching cycles" below
whether or not the contact life of the type
DSL 9 is sufficient for the application.
Each reversing contactor combination con­
sists of two identical DSL... contactors.
