209/219/229/249/279 SERIES HYDRAULIC MAGNETIC CIRCUIT PROTECTORS Introduction 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. 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. 209/219/229 MAGNETIC CIRCUIT PROTECTORS Terminal Style DIMENSION A 209 E-Frame circuit breakers may be specified with either screw terminals, stud or Number of Poles Dimensions A solderless connectors. 1 1.026 .010 26.06 3.30 A choice of front or back connected terminal styles is available.

Three inverse time delays are available to permit close coordination with various loads. Delays 51 and 61 are short delays for electronic loads. Delays 52 and 62 are The 249 is designed to allow selection of any one of two, three or four independent medium delays for mixed loads. Delays 53 and 63 are long delays for motor loads. power systems. This is accomplished with fool-proof sliding-gate handle covers. The number of sliding covers is one less than the number of power systems. With Current and Voltage Ratings this arrangement, it is impossible to switch ON more than one power system at Single pole and multi-pole breaker ratings are available up to 100 amperes, 240Vac a time. or 125Vdc. The special configuration for Marine use has a 120V/240Vac rating for current rating up to 100 amperes. Since the 249 Power Selector Breaker System is listed as a Branch Circuit Breaker per UL 489 and power switching is accomplished by UL listed breakers, it is usually Master Drawing not necessary to include additional branch service protection. Standard circuit breaker terminal and configurations are shown. For other types, consult factory. Standard options available include terminals for front or back connections, choice of trip time delay, current ratings to 100 amperes and single or multi-pole sections.
