Description
VA88 circuit breakers are intended for conducting current in normal mode and switching it off at short circuits, overload, inadmissible bucking as well as operational actuation and tripping of electric circuit parts. They are designed for use in electric units having the operative voltage limited to 400 V per rated current from 12,5 to 1600 A. Correspond to the requirements of EN 60947-1, EN 60947-2.
Advantages
- Two types of protection against overload and short circuit.
- Complete set of supplementary devices with the possibility of simple independent installation:
- – State contact KS47;
- – State contact KSV47;
- – Undervoltage trip RMM47;
- – Low-voltage release RN47.
- Indication of contact position.
- Latching on DIN-rail with double locking.
- Wide operating temperature range from –40 to +50° С.
- Updated wider engagement lever with improved contact area.
- Notches on contact terminals reduce heat loss and increase mechanical stability of the connection.
- Higher switching capacity of 10000A provides for installing VA47-100 as input circuit breakers.
