<strong>IPA</strong>/<strong>CPA</strong> <strong>Series</strong>Hydraulic Magnetic Circuit ProtectorsINTRODUCTIONThe <strong>Airpax</strong> <strong>IPA</strong>/<strong>CPA</strong> hydraulic-magnetic circuit protectorsprovide low-cost power switching, reliable circuit protectionand accurate circuit control for equipment in the internationalmarketplace.<strong>IPA</strong> models meet IEC spacing requirements that are mandatoryfor equipment which must comply with IEC specifications 601and 950 and VDE specifications 0804 and 0805. In addition, theyare UL Recognized as supplementary protectors per UL STD.1077, CSA Certified as supplementary protectors per CSA C 22.2-No. 235, TUV Approved to VDE 0642 (EN60934), CCC Approved(pending) and CE Compliant.Designed using the latest in sensitive hydraulic magnetictechnology, the <strong>IPA</strong> line adapts itself to many applications andenvironments. They’re ideal for data processing and businessmachines, medical instrumentation, broadcast equipment,vending and amusement machines, military applicationsand wherever precision operation is required. Temperaturedifferences which affect fuses and other thermal devices are nota concern.One important feature of this protector line is a “trip free” action,which means the circuit will trip in the presence of an overloadeven though the handle is held in the ON position. The delaymechanism senses the fault and the contacts open.The <strong>IPA</strong> is available in configurations including series and serieswith auxiliary switch, with a choice of delays and ratings in eitherDC, 50/60Hz or 400Hz versions. Single or multi-pole versionsare available, with a variety of pole arrangements to meet yourspecifications.83<strong>IPA</strong> <strong>Series</strong> - Introductionhttp://airpax.sensata.com

CONFIGURATIONS<strong>Series</strong> TripThe most popular configuration for magnetic protectorsis the series trip where the sensing coil and contacts are inseries with the load being protected. In addition to providingconventional overcurrent protection, the handle positionconveniently indicates circuit status.Auxiliary Switch (Applies to <strong>Series</strong> Trip Only)This is furnished as an integral part of a series pole insingle or multi-pole assemblies. Isolated electrically from theprotector’s circuit, the switch works in unison with the powercontacts and provides indication at a remote location of theprotector’s on-off status.Auxiliary switch contacts actuate simultaneously with themain breaker contacts, and will open regardless of whetherthe breaker contacts are opened manually or electrically. Forauxiliary switch ratings below 6Vac or 5Vdc, an auxiliaryswitch with gold contacts, designated as REG, is available.Gold contacts are not recommended for load current above100 milliamps. An optional auxiliary switch, RS, configurationallows an alarm or signal to be forwarded only upon electricaloverload, allowing for easier detection of fault circuit.TYPICAL RESISTANCE / IMPEDANCECurrent Ratings(Amps)1.383[35.13]<strong>Series</strong> Type (Except delays 40, 50, 60)DC(ohms)AC, 50/60Hz(ohms)AC, 400Hz(ohms)0.050 427 478 —0.100 100 103 204<strong>Series</strong> Trip0.250 19 20 340.500 4.6 6.3 8.20.750 2.04 2.06 3.521.00 0.91 0.92 1.862.50 0.17 0.19 0.285.00 0.045 0.046 0.0737.50 0.018 0.019 0.037.135[3.43] 10.0 0.013 0.014 0.02015.0 0.0072 0.0073 0.0109LINELINE20.0 0.005 0.0051 —25.0 0.003 0.0035 —DCR and Impedance values are based on measurements by the voltmeterammeter LOAD method.

HOW TO ORDERThe ordering code for <strong>IPA</strong>/<strong>CPA</strong> protectors may bedetermined by following the steps in the decisiontables shown here.1<strong>IPA</strong><strong>IPA</strong>P<strong>IPA</strong>H<strong>IPA</strong>HP<strong>CPA</strong><strong>CPA</strong>HFirst DecisionTypeOne toggle handle per unitUL RecognizedOne toggle handle per unitUL RecognizedPC board mountOne toggle handle per poleUL RecognizedOne toggle handle per poleUL RecognizedPC board mountOne toggle handle per unitUL Listed per UL489AOne toggle handle per poleUL Listed per UL489A2-1-11-111-6-66-666Second DecisionPolesSingle pole w/ quick connect terminals or PC board if P is used.Two pole w/ quick connect terminals or PC board if P is used.Three pole w/ quick connect terminals or PC board if P is used.Single pole w/ screw terminalsTwo pole w/ screw terminalsThree pole w/ screw terminalsNote:A The coding given permits a self-assigning part number. Other configurations may require afactory assigned part number. Typical examples are units with mixed ratings, combinations ofstyles or construction. With these, it is suggested that order entry be by description and/ordrawings and a part number will be assigned. Additionally, it is a standard policy to establish afactory assigned part number wherever a descriptive drawing exits to provide cross reference,traceability and manufacturing control.95<strong>IPA</strong> <strong>Series</strong> - Decision Tableshttp://airpax.sensata.com
