209 Series UL(489,489A,1500), TUV Up to 125A 10,000AIC
Circuit Breakers
The 209 family of circuit breakers includes components in the 209, 219, 229, 239, 249, 259, 269, and 279 series. The 209 Series 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. Utilizing the hydraulic-magnetic principle, the 209 Series products adapt 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. 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.

Trip Free
Will trip open on overload, even when forcibly held on. This prevents the operator from damaging the circuit by holding the handle in the ON position.
Trip Indication
The operating handle moves positively to the OFF position on overload.
Environmental Specifications
Moisture and fungus resistance is provided by the use of moisture resistant finishes. Special springs and treatment for all ferrous parts eliminate inherent moisture-related problems. The use of fungi inert cases and handles avoids fungus-related problems.
Current Ratings
209/219/229 may be supplied with these ratings: DC, 50/60Hz, 400Hz, 0.1 to 100 amperes. 279 types may be supplied with DC ratings only, 0.1 to 100 amperes.
Voltage Ratings
On 209/219/229, voltages up to and including 240Vac, 50/60Hz or 400Hz, or 125Vdc are available. Multi-pole units can be supplied for 277Vac/480Vac, 50/60Hz. 279 types are available with a voltage of 160Vdc. All units will be marked with the standard maximum voltage. UL Listed breakers will be labeled with the UL listed voltage.
Auxiliary Switch Ratings
When supplied shall be S.P.D.T. configuration with a maximum rating of 10 amperes 250Vac.
Mounting Considerations
A three-inch spacing must be provided between the circuit breaker and vent and any conductive surface. If closer than three inches is necessary, then an insulator must be installed on the conductive surface.
Solderless Connectors
Connectors are rated AL9 CU. and accept either copper or aluminum conductors. Units are suitable for use with both 60° and 75° wire. Optional pressure plate for fine stranded wire is available. Contact factory for details.
