209/219/229/249/279 SERIES
HYDRAULIC MAGNETIC CIRCUIT PROTECTORS
Introduction
Terminal Style
The 209, E-Frame circuit breaker combines power switching with accurate, reliable circuit protection in a compact single or multipole unit. The unit is
ideal for branch circuit applications such as EDP, air conditioners, panel boards and lighting controls.
The 209 is actually a family of circuit breakers available in one through six pole assemblies with a variety of configurations and terminal styles to
meet your application needs. First in this family is the 209, a general purpose E-Frame circuit breaker which complies with UL Standard 489. Other
members of the family include the 219, for manual controller applications, which complies to UL Standard 508, the 229, for supplementary protectors
applications, which complies to UL Standard 1077, and the 299, a Special Construction version.
209 E-Frame circuit breakers may be specified with either screw terminals, stud or
solderless connectors.
A choice of front or back connected terminal styles is available. The back connected
terminal style is available with stud terminals only. Front terminal style is available with
either screw terminals or solderless connectors.
Refer to Sixth Decision Table for front connected terminal information.
Barriers for back connected terminal styles are supplied on multi-pole units only. Line
and load connections may be made to either terminal and terminals will be identified as
shown on the following page.
Utilizing the hydraulic-magnetic principle, the 209 family adapts itself
to local applications and environments. Temperature conditions, which
affect fuses and other thermal devices, are not a concern. The magnetic
/ampere turn principle minimizes nuisance tripping due to temperature
variations.
Inrush currents, due to ferroresonant transformers, lamps and capacitive
filters, are now becoming more significant. Recognizing the need for this
type of protection, Airpax offers the unique inertial delay which is standard
for all 50/60Hz time delay units, but may be deleted where inrush is not a
problem. No extra cost or special order is required.
The 209 family of circuit breakers withstands high pulses without tripping
or affecting normal delay curves. This performance, however, does not
derate or sacrifice protection.
