1st shunt release (-Y1)
Position switch 3AX4206-0A
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.
The 1st shunt release (-Y1) is not designed for continu-
ous operation and is terminated within the circuit-breaker
via the auxiliary switch (-S1) at the factory.
The operator’s supply voltage is permitted to 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) DC 60 V is protected
against overvoltage by a varistor.
Power consumption
300 W to 370 W / VA (3AY1410-..)

Position switch (-S21) switches the motor off after charg-
ing the switch-on spring.
Position switches (-S3) and (-S4) open when the closing
spring is charged.
