3 Features The ultimate in compactness and operational capability Standardized basic dimenstions The height and depth dimensions are identical in all sizes to A. There are two common widths or frame size, from 8-A and from 5-A for the standard series. The panel cutout size is the same for all types of DH series AB, which makes it easy to arrange the ABs in switchboards. Maximum power from minimum volume was central to the design specification. With a depth of 9mm for the fixed type and 45mm for draw-out, it is one of the smallest ABs in the world. ABs with front connections are available off-the-shelf. Front connections are especially suitable for smaller-depth switchboards Geared toward the smallest depth in the world Direct connection of the isolating main contacts to the hinges of the fixed main contacts eliminates the need for intermediate conductors. Allowing the DH series ABs have the world s smallest depth resulting in saving in switchboards. More than twenty design patents have been registered for the DH series AB. DH Series DB series H: 46 W: 54 Standard type 8~A High breaking type 5~A D: 45 W: 46 5~A 6~A W: 6 4A D: 75 Saved Space Increased accessibility from the front It enhances ease of installation, operation, and maintenance. The double insulated design ensures that most accessories can be safely and easily, installed by the user. ontrol, auxiliary and position switch terminals are mounted at the front on the AB body for easy access. Due to the increased level of harmonics within the distribution network, the neutral phase is fully rated as standard. No extra arc required, vertical stacking permitted The DH series AB dissipates all arc energy within its unique Double Break arc chamber. The internal energy dissipation within the AB allows the clearance distance of the AB to nearby earthed metal to be zero. This will assist in minimizing switchboard height and costs. 8 onnection to the control circuit No extra arc required Replacement of internal parts (Removing the front cover enables replacement of internal parts.) Manual operation Draw-out operation

4 Features A high performance and reliability Very fast interruption by Double Break system The unique Double Break main contact system ensures extremely fast interruption of short-circuit currents and substantially reduces main contact wear. The internally symmetrical Double Break structure allows reverse power connection. No clamp screws used for the main circuit contact units There are no clamp screws or flexible leads in the main circuit contact units. This substantially enhances the durability of the main circuit contact units and improves the reliability in ON-OFF operation. Isolating main contact Fixed main contact Moving main contact Enhanced selectivity Replacement of the main contacts At Fuji we are so concerned about selectivity that all our protection relays have LSI characteristics as standard. This provides an adjustable time delay on overload (L) and also the l t ramp characteristic (S). As shown, these are essential to provide selectivity when grading with other protective devices such as downstream fuses and upstream relays. The standard LSI curve provides more than five million combinations of unique time current characteristics. Zone selective interlocking is available to provide zero time delay selectivity. As the rated breaking capacity is identical to the rated short-time withstand current full selectivity can be achieved. The fixed and moving main contacts can easily be replaced in the field, thus prolonging the life on the circuit breaker. hanging each pole takes around 5 minutes. L: Long time delay S: Short time delay I: Instantaneous erformance Rated breaking current (at 44V A) Type and rated current DH8 DH DH6 DH 8A 5A 6A A With INST trip function With ST delay trip function (Without INST trip/mr functions) DHH DH6H DHH 5A 6A A DH5 DH 5A A DH6 DH DH5 DH 6A A 5A A DH4 65kA 8kA 85kA ka ka 4A Rated short-time withstand current (for sec.) Note: If the AB is DH-H type or DH- type without INST trip/mr function, the rated breaking capacity will decrease down to the rated latching current. 4

5 Features FUJI AB provides positive protection for electric power systems. For general feeder circuits (L-characteristic) For general feeder circuits (R-characteristic) For generator protection (S-characteristic) The Fuji AB DH series is equipped with an RMS sensing over-current release (OR) having a wide range of protection functions and capabilities. Optimum protective coordination Why use a separate panel mounted protection relay when you can have all the benefits of I.D.M.T. protection integral to the AB? Fuji AB is available with a choice of flexible protection curves to assist in selectivity applications. All these curves are user definable and comply with IE Standard transformer and generator protection characteristics are also available. I, t It I t=s.i. I t=v.i. AGR-L Industrial & transformer protection AGR-R haracteristics to IE 655- AGR-S Generator protection I 4 t=e.i. Inverse Definite Minimum Time (I.D.M.T.) S.I. Standard lnverse V.I. Very lnverse E.I. Extremely lnverse Standard OR with adjustment dial Type AGR-B Standard OR with LD Type AGR-B,B Enhanced OR with LD Type AGR-B Overload protection Adjustable from 4 % of rated current. True r.m.s detection up to the 9th harmonic, a distant vision for the competition who rarely see past the 7th. Neutral protection for all those Triple-N harmonics, such as rd, 9th and 5th. Also in case we forgot to mention, a thermal memory as standard! Two channel pre-trip alarm function (S-characteristic) This function can be used to monitor and switch on additional power backup to feed critical circuits. For example, the function can be set so that when a pre-trip alarm is activated, an emergency generator starts to ensure a constant supply. This feature is only available on some AGR OR models with a generator S characteristic. N-phase protection function (optional) In -phase, 4-wire systems that contain harmonic distortion, the rd harmonic may cause large currents to flow through the neutral conductor. The N-phase protection function prevents the neutral conductor from sustaining damage or burnout due to these large currents. Available in all ORs except for generator S characteristic types. Reverse power trip function (S-characteristic) (The first-ever feature for ABs) This feature provides additional protection when paralleling generators. The AGR OR for generator protection with the reverse power trip function, negates the need for installation and wiring in an external reverse power relay. This feature is available using an AGR OR with a generator S type characteristic only. Ground fault trip function This function eliminates external relays to provide a ground fault protection to TN- or TN-S power distribution systems on the load side. Ground faault protection on the line side is also available as an option. Reverse phase protection function This function detects the negative-phase current occurring due to reverse phase or phase loss and precents burnout of a motor or damage to equipment. ontact temperature monitoring function (optional) This function monitors the temperature of the ABs main contacts. An alarm indicates when the temperature exceeds 55. ontinuous monitoring of the contact temperature provides valuable input for preventative and predictive maintenance programs. Advanced L..D display, Over urrent Relay The AGR-B OR comes standard with an LD display. It can monitor and indicate phase currents, voltages, power, energy, power factor, frequency, and more. : Available for type AGR-BS, BS. : Available for type AGR-B, B OR. 8 5
