Description
Arcing time The interval of time from the first initiation of an arc and the instant of final arc extinction
in all poles.
Break time The interval of time between the initiation (command) of the opening operation and
the instant of final arc extinction in the last-pole-to-clear (=opening time and arcing time).
Close-open contact time The interval of time - in a make-break operating cycle - between the instant when
the contacts touch in the first pole in the closing process, and the instant when
the contacts separate in all poles in the subsequent opening process.
Motor operating
mechanism
For DC operation, the maximum power consumption is approx. 350 W.
For AC operation, the maximum power consumption is approx. 400 V A
The rated current of the motor protection equipment is shown in the following table:
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 table:
Closing solenoid (Y9) The closing solenoid closes the circuit-breaker. After completion of a closing operation,
the closing solenoid is de-energized internally. It is available for AC or DC voltage.
Power consumption: 140 W or 140 VA.
