Operating times

Number of operating cycles

Closing time The interval of time between the initiation (command) of the closing operation and theinstant when the contacts touch in all poles.

Opening time The interval of time between the initiation (command) of the opening operation and theinstant when the contacts separate in all poles.

Arcing time The interval of time from the first initiation of an arc and the instant of final arc extinctionin all poles.

Breaking time The interval of time between the initiation (command) of the opening operation and theinstant of final arc extinction in the last quenching pole (= opening time and arcing time).

Close-open contact time The interval of time - in a make-break operating cycle - between the instant when thecontacts touch in the first pole in the closing process, and the instant when the contactsseparate in all poles in the subsequent opening process.

Motor operating

mechanism

The operating mechanisms of the 3AH circuit-breakers are suitable for auto-reclosure.

For DC operation, the maximum power consumption is 350 W. For AC operation, themaximum power consumption is 400 VA.

The rated current of the motor protection equipment (option) is shown in the followingtable:

Description


The supply voltage may deviate from the rated supply voltage specified in the table by -15% to +10%.

The breaking capacity of the auxiliary switch 3SV92 is shown on the following tables:

Closing solenoid (Y9) The closing solenoid 3AY1510 closes the circuit-breaker. After completion of a closingoperation, the closing solenoid is de-energised internally. It is available for AC or DCvoltage. Power consumption: 140 W or 140 VA.

Shunt releases The shunt releases are used for automatic and deliberate tripping of circuit-breakers.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 principles are used: The shunt release (Y1) 3AY1510 is used as standard in the basic circuit-breaker

version. With this design, the circuit-breaker is opened electrically. Powerconsumption: 140 W or. 140 VA.

The shunt release (Y2) 3AX1101 with energy store is fitted if more than one shuntrelease is required. With this design, the electrical opening command is transferredmagnetically and thus, the circuit-breaker is opened. Power consumption: 70 W or50 VA.

Undervoltage release Undervoltage releases are tripped automatically through an electromagnet or

deliberately. The deliberate tripping of the undervoltage release generally takes place viaa NC contact in the tripping circuit or via a NO contact by short-circuiting the magnet coil.With this type of tripping, the short-circuit current is limited by the built-in resistors.Power consumption: 20 W or 20 VA.

Circuit-breaker trippingsignal

When the circuit-breaker is tripped by a release, there is a signal. If the circuit-breaker istripped deliberately with the mechanical pushbutton, this signal is suppressed.

C.t-operated release (Y6) The c.t.-operated release 3AX1104 is adequate for a tripping pulse of " 0.1 Ws inconnection with adequate protection systems. It is used if auxiliary voltage is missing,tripping via protection relay.
