IPA/CPA Series Magnetic Circuit Protectors Introduction * 83 Poles * 84 PC Board Mount * 87 Configurations * 89 Operating Characteristics * 90 Delay Curves * 91 Specifications * 93 Decision Tables * 95 IPA/CPA Series Hydraulic Magnetic Circuit Protectors INTRODUCTION The AirpaxTM IPA/CPA hydraulic-magnetic circuit protectors provide low-cost power switching, reliable circuit protection and accurate circuit control for equipment in the international marketplace. IPA models meet IEC spacing requirements that are mandatory for equipment which must comply with IEC specifications 601 and 950 and VDE specifications 0804 and 0805. In addition, they are UL Recognized as supplementary protectors per UL STD. 1077, CSA Certified as supplementary protectors per CSA C 22.2No. 235, TUV Approved to VDE 0642 (EN60934), CCC Approved (pending) and CE Compliant. Designed using the latest in sensitive hydraulic magnetic technology, the IPA line adapts itself to many applications and environments. They're ideal for data processing and business 83 IPA Series - Introduction machines, medical instrumentation, broadcast equipment, vending and amusement machines, military applications and wherever precision operation is required. Temperature differences which affect fuses and other thermal devices are not a concern. One important feature of this protector line is a "trip free" action, which means the circuit will trip in the presence of an overload even though the handle is held in the ON position. The delay mechanism senses the fault and the contacts open. The IPA is available in configurations including series and series with auxiliary switch, with a choice of delays and ratings in either DC, 50/60Hz or 400Hz versions. Single or multi-pole versions are available, with a variety of pole arrangements to meet your specifications. http://airpax.sensata.com IPA Series (PCB Mount) SINGLE POLE (ONE HANDLE) .635 [16.13] Mounting Detail LINE .551 [14.00] .535 [13.59] 60 1.732 [43.99] 1.988 MAX.

IPA Series - Poles 84 MULTI-POLE CIRCUIT PROTECTORS Two Pole Protectors An assembly consisting of two single pole units, having their trip mechanisms internally coupled and with a single toggle handle, forms the IPA-11 with quick-connect D.I.N.-style terminals. Individual poles may differ in ratings, delays and internal connections. An auxiliary switch may be included in either or both poles, allowing you to mix SELV and hazardous voltages. Rugged screw-type terminals can be provided, in which case the designation would be IPA-66. The IPAH offers a toggle handle for each pole. all units simultaneously. A single toggle handle operates all three poles for quick and convenient control, or if preferred, a handle per pole is available. The individual poles need not have identical characteristics and any series trip pole may have an auxiliary switch. If screw-type terminals are required, the breaker designation will be IPA-666 for a three pole version. Three Pole Protectors The three pole construction consists of three single pole units assembled with an internal mechanical interlock which actuates Handles The IPAH two and three pole models are available with a handle per pole. Breaker poles are numbered consecutively when viewed from the terminal side, with the ON position up, starting with Pole #1 on the left side and proceeding to the right.

Isolated electrically from the protector's circuit, the switch works in unison with the power contacts and provides indication at a remote location of the protector's on-off status. Auxiliary switch contacts actuate simultaneously with the main breaker contacts, and will open regardless of whether the breaker contacts are opened manually or electrically. For auxiliary switch ratings below 6Vac or 5Vdc, an auxiliary switch with gold contacts, designated as REG, is available. Gold contacts are not recommended for load current above 100 milliamps. An optional auxiliary switch, RS, configuration allows an alarm or signal to be forwarded only upon electrical overload, allowing for easier detection of fault circuit. 1.383 [35.13] Series Type (Except delays 40, 50, 60) 10.0 15.0 LINE 20.0 LINE 25.0 DCR and Impedance values are based on measurements by the voltmeter LOAD method.
