Under voltage release |
· Under-voltage release
Wring diagram of the under-voltage module connected externally (the internal accessories in the dotted frame)
Ue: AC50Hz 230V,400V
When the operation voltage is 35%~70% of the rated voltage, the under-voltage release should
make the breaker trip correctly.
When the operation voltage is 85%~110% of the rated voltage, the under-voltage release should
make the breaker close.
In case of the operation voltage less than 35% of the rated voltage, the under-voltage should
prevent the breaker from closing.
Note: Only the under-voltage release should be energized in advanced, the breaker could be
recramped and turned-on, otherwise the breaker will be damaged.

Shunt release |
· Shunt release
Scheme of wiring(the internal accessories in the dotted frame) "K?is the slow motion switch normal-close contact connect the coil in series in the shunt release. It turns-on or turns-off voluntarily as soon as the breaker on or off.
Voltage rating: AC50Hz 230V or 400V, DC 110V 220V
The shunt release should make the breaker trip reliably when the operation voltage is 70%~110% of the rated control voltage.
