Closing time = the interval of time between the initiation of the closing operation and the instant when the contacts touch in all poles. Opening time = the interval of time between the initiation of the opening operation and the instant when the contacts separate in all poles. Arc time = the interval of time between the instant of the first initiation of an arc and the instant of final arc extinction in all poles. Breaking time = the interval of time between the beginning of the opening time of a circuit breaker and the end of the arcing time. Close-open-time = the interval of time (in a make-break operation cycle) between the instant when the contacts touch in the first pole in the closing process, and the instant when the arcing contacts separate in all poles in the subsequent opening process Switching duties The operating mechanisms of the 3AH3 circuit-breakers are suitable for rapid auto-reclosure. Breakers for a rated short-circuit breaking current of ≥40kA are, at rated data levels, suitable for rapid load transfer and till 31.5kA for rapid auto-reclosure. Motor operating mechanism The maximum DC power input is 500 W (approx.) the maximum AC power input is 650VA (approx.). During part of the short spring charging time the motor operate in the overload range. The recommended rating for motion protection devices are shown in Fig.1/6 (the protection devices are not supplied with the vacuum breakers and must be ordered separately) *) MCB with G characteristic Fig.1/6 Rated currents of motor protection device.

Shunt releases (shunt opening releases) The shunt releases are used for automatic tripping of circuit-breakers by means of appropriate protective relays and for deliberate tripping by other electrical means. They are designed for connection to external voltage (DC or AC voltage). In special cases, for deliberate tripping, they can also be connected to a voltage transformer. Shunt releases based on two different operating principles are used. Shunt release (Y1) 3AY1510 The 3AY1510 shunt release is used as standard in the basic circuit-breaker version, with this design, the electrically supplied tripping pulse is passed to the ″open″ latching mechanism by means of a direct-action solenoid armature and the circuit-breaker is thus opened. It is available for both AC and DC operation. After completion of an opening operation, the AY1510 shunt release is de-energized internally. In operation with AC voltage, a rectifier module 3AX1525-1F is installed in the circuit-breaker. Power consumption approx. 140 W/VA

Shunt release (Y2) 3AX1101 1)

The 3AX1101 shunt release is fitted if more than one shunt release is required. With its design, the electrical opening command is transferred in boosted form to the ″Open″ latching mechanism via a solenoid armature through unlatching of a energy store and thus the circuit-breaker is opened. Any varistors and rectifiers required are integrated in the release. Power consumption: <60W or <55VA Undervoltage release (Y7) 3AX1103 1)

Undervoltage release consist of a stored-energy mechanism, an unlatching mechanism and an electromagnet system which is connected continuously to the supply when the circuit-breaker is in the close state. If this voltage drops to below a certain value the unlatching mechanism is released and opening of the circuit-breaker is thus initiated via the stored-energy mechanism. The deliberate tripping of undervoltage release generally takes place via an NC contact in the tripping circuit. But it can also be carried out via an NO contact by short-circuiting of the magnet coil. With this type of tripping, the short-circuit current is limited by the built-in resistors (see circuit diagram Fig.3/4) Under voltage releases can also be connected to voltage transformers. When the operating voltage drops to impermissibly low levels, the circuit-breaker is tripped automatically. Power consumption: <6.5 W or <7.5 VA CT-Operated release (Y4) 3AX1102 1)

CT-operated releases consist of a stored-energy mechanism, an unlatching mechanism and an electromagnet system. When the tripping current is exceeded (90% of the CT-operated release rated current) the unlatching device of the stored-energy mechanism is released and thus opening of the circuit-breaker is initiated. In addition to the primary current transformer, matching transformers are required for application of the CT-operated releases. Power consumption for 0.5A and 1A<6VA at 90% of the rated current and with open armature. CT-operated release (Y6) 3AX11041) (Low-energy release 0.1Ws) In connection with a solid-state release (7SJ41 overcurrent time protection or similar) and low-power primary current transformers (window-type transformers), it is possible with the 3AX1104 to create a CT-operated release without additional supply voltage. The 3AX1104 is of similar design as the 3AX1101 /1102 releases. With its coil data and its low energy requirement of < 0.1Ws, its designend to be directly actuated by a release impulse provided by a capacitor of the above-mentioned electronic release systems.

Breaker tripping signal, cut-out switches (S6 and S7)

When the vacuum circuit-breaker is tripped by means of a release, the position switch S6 briefly makes contact. This contact making can be used for signalling. In the event of intentional mechanical tripping, the cut-out switch S7 breaks this contact. Varistor module (V1 to V3) 3AX1526 1) The disconnection of inductive loads in DC circuits may cause switching overvoltage which pose a risk to electronic control units. In order to prevent this, the inductances of the circuit-breaker mechanism and control (motor, closing solenoid, shunt release and auxiliary contactor) can be connected to varistor (with DC operation). For rated operating voltage of 60V to 220V DC the varistor module 3AX1526 is available as an accessory; it limits the overvoltage to about 500V. The module contains 2 separate varistor circuits. Electrical local closing/electrical interlocking1)

In the basic version, the closing spring must be released mechanically if the breaker is to be closed locally. A version with electrical local closing can also be supplied. In this version, the making circuit of the circuit-breaker is activated electrically via a push-button. In this way, allowance can also be made for station-specific interlocks, and undesired making operations prevented. For example, interlocking of the circuit-breaker is possible via the auxiliary contact of a disconnector. Circuit-breaker with electrical local closing cannot be closed mechanical. Mechanical interlocking1) Operating mechanism of disconnectors can be fitted with a mechanical switchgear interlocking facility. The disconnector and the associated circuit-breaker are in this case interlocked mechanically. The sensing parts check the switch position of the circuit-breaker and prevent if from closing mechanically and electrically if the associated disconnector is not in a position to allow safe operation. On the other hand, the disconnector is prevented from being operated when the circuit-breaker is closed. The mechanical interlocking facility can also be used to interlock breaker trucks or draw-out breaker parts. Adjustment instruction: 3G 460 00127 (3AX 1520-3C) Dimensions and weight The dimensions and weights of the vacuum circuit-breaker are shown in the relevant drawings. For planning purposes, the drawings showing detailed overall dimensions, can be ordered through the appropriate Siemens agency. The weight is also stated on the breaker rating plate.

1) Can be ordered on request, retrofitting possible.

5. For test operations with the motor mechanism switch on the supply voltage. The motor will start immediately and charge the closing spring (62.). check the mechanical and electrical indication of the charging state of the closing spring. Actuate the mechanism as indicated under 4. And check the mechanical and electrical state indication.

6. Check the auxiliary switch S1 (68.) and position switches

(50.4.1) electrically in both end positions by actuating the 3AH3 vacuum circuit-breaker.

7. Also check-by electrical actuation – the function of the

closing solenoid Y9 (53.1) and all fitted shunt release. When correct functioning of the 3AH3 V-breaker has been ascertained it can be put into service. Charging the closing spring When the supply voltage is applied the motor (50.4) automatically charges the closing spring (62.). Should the supply fail the closing spring (62.) can also be charged by hand crank (50.). In the lattercase, as shown in Fig.4/1,the hand crank(50.) is inserted with the forwards pushed adapter (50.6) through the opening (50.1) onto hand crank coupling (50.5) and turned clockwise, until the symbol "closing spring discharged” shown in the indicator opening (55.3) is changed to "closing spring charged” (Fig. 4/2). The adapter (50.6) is designed so that the hand crank (50.) is decoupled on the recovery of the motor supply. Closing If operation is not blocked by the mechanical interlock, press the close push-button (53.) or the corresponding control switch until the 3AH3 vacuum circuit-breaker closes and both indicates and signals this state. After closing (and, if applicable, releasing of the close push-button (53.) the closing spring (62.) is immediately and automatically recharged the "closing spring charged” (55.) and indication becomes visible once again. Tripping The opening spring (64.) is charged during closing. To trip the breaker press the open push-button (54.) or corresponding control switch until the V-breaker trips and both indicates and signals this state.

5. 进行测试时接通马达机构电源, 此时马达立即启动并对合闸弹簧 (62.) 储能. 检查合闸弹簧在储能状态时的电气和机械指示. 然后按第 4 点所述操作, 再检查此状态时的电气及机械指示. 6. 通过操作 3AH3 断路器, 检查辅助开关 S1 (68.) 和位置开

关 (50.4.1) 在合分位置的电气状态. 7. 通过电气手段检查合闸线圈 Y9 (53.1) 以及所有脱

扣线圈. 当 3AH3 断路器以上功能都得到验证后, 可以投入使用. 合闸弹簧储能当电源接通后,马达 (50.4) 自动对合闸弹簧 (62.) 储能. 如电源

有故障时, 可通过手柄 (50.) 进行储能. 对于后者,如图.4/1 所示, 手柄 (50) 的适配头 (50.6) 通过面板开孔 (50.1) 插入手柄耦合杆 (50.5) 顺时针转动, 直到面板开孔 (55.3)上的标志”合闸弹簧未储能”转换为”合闸弹簧已储能”(图.4/2). 手柄适配头 (50.6) 经专门设计保证在马达电源恢复时手柄顺利从耦合杆退出. 合闸在机械联锁处于防松状态时, 按″合闸″按钮 (53.)或相应控制开关使 3AH3 断路器合闸并且面板指示和电气信号都处于对应状态. 合闸后 ( 合闸按钮 (53.) 释放后), 合闸弹簧 (62.) 立即自动再

储能, 储能状态指示重新为”合闸弹簧已储能” (55.). 分闸分闸弹簧 (64.) 在合闸的过程中被压缩储能. 按”分闸”按钮 (54.) 或相应控制开关使断路器分闸并且面板指示和电气信号都处于对应状态.

This is caused by mechanical deformation (compression) and/or erosion. We have taken measures in design to ensure that such minor changes in the travel do not affect the switching performance of our circuit breakers. Checking the vacuum Such a check should be made if there is any risk of an interrupter having developed a leak. Busbar and cable connections must be split. The check is performed with an HV test unit. If necessary, further information may be obtained from the appropriate Siemens Regional Office.
