3 SIGLE PLE CIRCUIT PRTECTRS ITRDUCTI The 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 60 and 950 and VDE specifications 0804 and In addition, they are UL Recognized as Supplementary Protectors per UL 077, CSA Certified as Supplementary Protectors, per CSA 22.2 o. 235, TUV Approved to VDE 0642 (E60934), 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 machines, medical instrumentation, broadcast equipment, vending and amusement machines, military applications and wherever precision operation is required. ne 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 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. Single Pole Breaker (one handle) LIE.732 [43.99].988 MAX.

4 MULTI-PLE CIRCUIT PRTECTRS 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- with quick-connect D.I..-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. Three Pole Protectors The three pole construction consists of three single pole units assembled with an internal mechanical interlock which actuates 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 protector designation will be IPA-666 for a three pole version. Protector poles are numbered consecutively when viewed from the terminal side, with the position up, starting with Pole # on the left side and proceeding to the right. Handles The IPAH two and three pole models are available with a handle per pole. Two Pole Breakers (one handle) Three Pole Breakers (one handle).295 MAX. [32.89].935 MAX.

8 CIGURATIS Series Trip The most popular configuration for magnetic protectors is the series trip where the sensing coil and contacts are in series with the load being protected. In addition to providing conventional overcurrent protection, the handle position conveniently indicates circuit status. Series Trip.383 [35.3].35 [3.43] LIE LIE LAD Switch LAD Series Auxiliary Switch (Applies to Series Trip nly) This is furnished as an integral part of a series pole in single or multi-pole assemblies. 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 protector contacts, and will open regardless of whether the protector contacts are opened manually or electrically. or 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 00 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.

10 DELAY CURVES DC, 50/60Hz, 400Hz Delay Curves (typ) DC Delay Curves (typ) A choice of delays is offered for DC, 50/60Hz and 400Hz applications. Delays 40, 59 and 69 provide fast acting, instantaneous trip and are often used to protect sensitive electronic equipment (not recommended where a known inrush exists). Delays 4, 5 and 6 have a short delay for general purpose applications. Delays 42, 52 and 62 are long enough to start certain types of motors and most transformer and capacitor loads. Delays 400, 500 and 600 are long delays for special motor applications.

14 DECISI TABLES How to rder The ordering code for protectors may be determined by following the steps in the decision tables shown here. ote: A The coding given permits a self-assigning part number. ther configurations may require a factory assigned part number. Typical examples are units with mixed ratings, combinations of styles or construction. With these, it is suggested that order entry be by description and/or drawings and a part number will be assigned. Additionally, it is a standard policy to establish a factory assigned part number wherever a descriptive drawing exits to provide cross reference, traceability and manufacturing control.
