Transformer operated releases (-Y4), (-Y5) 3AX1102-.., (-Y6) 3AX1104-..
The transformer operated releases (-Y4), (-Y5) and (-Y6) consist of an energy store,
an unlatching fixture and an electromagnetic system. If the tripping current is ex-
ceeded (90 % of the transformer operated release’s rated current), the stored ener-
gy mechanism is unlatched, thus initiating opening of the vacuum circuit-breaker.
For use of the transformer operated releases, auxiliary transformers are also need-
ed for adaptation, in addition to the main current transformers.
Transformer-operated releases (-Y4) and (-Y5) are equipped with a rectifier.
Power consumption for 0.5 A and 1 A ≤ 6 VA at ≤ 90 % of the transformer operated
release’s rated current and with open armature.
Power consumption 10 W / VA
