The control voltage (including releases) is protected with 8 A.
Release
Releases trip the switch-fuse combination. The electrical opening command is transmitted to the
OPEN latch via a magnet armature by unlatching an energy store.
Depending on the operating mechanism used, up to 2 releases can be used.
▪
Shunt release (-Y1, -Y3)
Shunt releases (optional) are used to trip or electrically open the switch-fuse combination.
The opening command is executed by application of an auxiliary voltage (AC or DC,
depending on the design option).
After opening the switch-fuse combination, the release is de-energized internally.
