Components

Under-voltage release

US: AC50/60 Hz 400V,230A

When the operation voltage is 35%-70% of the rated voltgae, 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 shouldd 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 is energized in advance, can the breaker be recramped and turned-on, otherwise the breaker will be damage

Shunt Release

Us: AC50/60Hz 230V 400V; DC110V 220V

The shunt release should make the brealer trip reliably when the operation voltage is 70%-110% of the rated control voltage.

Auxiliary Contact / Alarm Contact

Auxiliary contact and alarm contact: Auxiliary contact is as same as Alarm contact,
