Closing solenoid (Y9) 3AY1510
1 st shunt release (Y1) 3AY1510
The closing solenoid Y9 unlatches the charged closing
spring and switches the vacuum circuit-breaker on
electrically . It is available for DC or AC voltage .
The closing solenoid Y9 is not designed for continuous
operation and is automatically deactivated within the
circuit-breaker.
The operator's supply voltage may deviate from the
rated supply voltage of the vacuum circuit-breaker by
-15 % up to +10 %.
The closing solenoid Y9 can be operated using AC or
DC voltage and is protected against overvoltage.
Power consumption is approximately 140 W / VA

In the case of the 1st shunt release Y1, the electrically
fed tripping pulse is passed to the "OPEN" latch by
means of a directly acting magnet armature, thus
switching off the vacuum circuit-breaker.
The 1st shunt release Y1 is not designed for continuous
operation and is automatically deactivated within the
circuit-breaker.
The operator's supply voltage may deviate from the
rated supply voltage of the vacuum circuit-breaker by -
30 % to +10 % in the event of DC voltage and by -15 %
to +10 % in the event of AC voltage.
The 1st shunt release Y1 can be operated using AC or
DC voltage and is protected against overvoltage.
Power consumption is approximately 140 W / VA
