Closing solenoid (Y9) 3AY1510
1st shunt release (Y1) 3AY1510
The closing solenoid Y9 unlatches the charged closing
spring and switches the vacuum circuit-breaker module
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 cir-
cuit-breaker.
The operator's supply voltage may deviate from the
rated supply voltage of the vacuum circuit-breaker mod-
ule by -15 % 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 switch-
ing off the vacuum circuit-breaker module.
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 mod-
ule 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
