Temperature differences which affect fuses and other thermal devices are not a concern. IEG models meet IEC spacing requirements which is mandatory for equipment that 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 C22.2-No. 235, VDE Approved to VDE 0642 (EN60934), CCC Approved and CE Compliant. IAG models are for those applications where the unit's inherent attributes are desired, but compliance with the various standards is not required. 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. Designed using the latest in sensitive hydraulic magnetic technology, the IAG/IUG/IEG/CEG/LEG line adapts itself to many applications and environments. They're ideal for data processing and business machines, medical instrumentation, broadcast 99 IAG Series - Introduction The IAG/IUG/IEG/CEG/LEG is available in a wide variety of configurations including series, series with auxiliary switch, shunt and relay with a choice of delays and ratings in either DC, 50/60Hz or 400Hz versions. Handles come in seven different colors and international markings are standard. Single or multipole versions are available, with a variety of pole arrangements to meet your specifications. Four pole models require a double toggle handle. Units with a handle per pole come in one through six pole assemblies. http://airpax.sensata.com IAG Series SINGLE POLE CIRCUIT PROTECTOR Single Pole Mounting Detail +.010 -.000 .625 .590 [15.00] MAX. 2X 6 - 32 THREAD .140 [3.56] DEEP M3 ISO THD.

The handle position conveniently indicates circuit status. In addition to providing conventional overcurrent protection, it's simultaneously used as an on-off switch. Shunt Trip The shunt trip is designed for controlling two separate loads with one assembly. The control is established by providing overload protection for the critical load. When the current through this load becomes excessive and reaches the trip point, the protector will open and remove power from both loads simultaneously. The total current rating of both loads must not exceed the maximum contact rating.

IAG Series - Decision Tables 118 1 LEG DECISION TABLES The ordering code for LEG circuit breakers may be determined by following the decision steps in the tables shown here. The coding given permits a self-assigning part number but with certain limitations. Special applications may require a factory-assigned part number. Typical examples are units with mixed ratings, combinations of styles, or constructions not listed in the third decision table. With these, it is suggested that order entry be by description and/or drawings and a part number will be established. Additionally, it is standard policy to establish a factoryassigned part number whenever a descriptive drawing exists to provide cross reference, traceability and manufacturing control. First Decision Select Type and Terminal Type Description Handle and Mounting Options LEG LMG One toggle handle per unit One toggle handle per unit mid-trip indication Standard toggle/mounting, no designation required LEGH One toggle handle per pole LMGH One toggle handle per pole mid-trip indication Note: All types are UL489 listed, CUL certified 2 To determine the ordering number for your particular LEG unit, simply follow the steps shown. You may use this number to place an order or as a reference for further questions you may have. Toggle w/ snap-in mounting ZX ZX Rocker w/ integral mounting* BX BX Rocker w/ integral mounting Note: Add "F" for flat screw terminals * Not available on mid-trip units Second Decision Poles and Terminals Push-on Terminals Screw Terminals 1 6 Single pole 11 66 Two pole *Not available in toggle seal handle type. When specifying a circuit breaker for AC motor start or high inrush applications, the peak amplitude and surge duration should be specified for factory assistance in rating selection. For example, the following is the code for a single pole, LEG screw type terminal, series unit with auxiliary switch, designed for operation in a 50/60Hz circuit. It has a short time delay, a rating of 20 amperes, a black marked handle and is VDE approved.

Switch is located in the right-hand pole (viewed from terminal end) unless otherwise specified. Notes: A.When "A" (metric thread mounting) is specified in the sixth decision in combination with screw terminal option in the second decision, metric screw terminals are supplied. 4 - 01 - V For addition of inertial delay, add an "F" to any delay numeral. (Not available on units rated at 125VAC). * CEG types are only available with DC ratings V = VDE Approved The shaded areas denote VDE approval options. This approval requires the addition of a V at the end of the part number. The V will be added to any part number formed entirely from shaded decisions. If non-shaded areas are selected, the unit will not be VDE Approved, but other approvals still apply. C = CCC Approved This approval requires the addition of a C at the end of the part number. The unit will not be VDE Approved. B.LEG, LEGH, LEGS, LEGHS, LEGZX and LEGBX circuit breakers are designed to meet 8mm creepage and clearance requirements for installation Category III, Pollution Degree 3, Case A as measured in IEC 664. Intended for use in equipment designed to comply with IEC 601 and 950 and VDE 0804 and 0805. 119 LEG Series - Decision Tables http://airpax.sensata.com 6 Fifth Decision Rated Current ROCKER HANDLE COLOR Sixth Decision INDICATING COLOR ON Optional ON ROCKER HANDLE COLOR OFF Standard hardware.
