Instructions for Low Voltage Power
Circuit Breakers Types DS and DSL
EATON CORPORATION www.eaton.com
Introduction
These instructions cover the description, operation and
maintenance of Eaton Type DS and Type DSL
Low Voltage AC Power Circuit Breakers and Type DS
Drawout Fuse Trucks. These breakers are usually sup-
plied as part of low voltage metal enclosed switchgear of
the four-position drawout type. These instructions apply
only to the circuit breaker and its auxiliary drawout details
which have been designed as a completely integrated
drawout unit. Type DS Breakers (not DSL) may also be
supplied in a fixed mounted version. In this case the sec-
tions of this book referring to the levering device, position
interlocks, and spring discharge interlock will not apply.
The DS and DSL Circuit Breakers operate on the mag-
netic De-ion principle of interruption. In these br
eakers
the arc rises into a series of insulated steel plates. The
plates break the rising arc into a series of smaller arcs to
cool and extinguish them and funnel the heat to ambient
air.
DS and DSL Breakers are available for application at volt-
ages from 208 to 600 Vac; with continuous currents of 50
to 4000 amps; and with interrupting capabilities up to
200,000 amps. Refer to the breaker nameplate for the
complete rating information for any given breaker. Break-
ers conform to NEMA, ANSI, and IEEE standards.
TYPE DS AND DSL BREAKERS ARE PROTECTIVE
DEVICES. AS SUCH, THE Y ARE MAXIMUM CUR-
RENT RATED DEVICES. THEREFORE, THE Y
SHOULD NOT UNDER ANY CIRCUMSTANCES BE
APPLIED OUTSIDE THE IR NAMEPLATE RATINGS.
OPERATION OUTSIDE OF THESE RATINGS MAY
CAUSE THE EQUIPMENT TO FAIL, RESULTING IN
BODIL
Y INJURY AND P
ROPERTY DAMAGE.
The available DS and DSL Breakers and their rated per-
formance capabilities are given in Tables 1 and 2.
Also short-time ratings.
Short circuit ratings of non-automatic breakers except the DS-840 which is 65,000.
Maximum voltages at which the interrupting ratings apply are:
System Voltage
Maximum Voltage
208 or 240 254
480 508
600 635
Interrupting ratings are based on the standard duty cycle con-
sisting of an opening operation, a 15 second interval and a
close-open operation, in succession, with delayed tripping in
case of short-delay devices.
The standard duty cycle for short-time ratings consists of main-
taining the rated current for two periods of 1/2 second each,
with a 15-second interval of zero current between the two periods.
