Description
Modular circuit breakers (MCB) VA47-29 are intended for protecting distribution and group systems having different loads: – electric appliances, lighting – B characteristic switches; – drives with moderate starting currents (compressor, fan group) – C characteristic switches; – drives with high starting currents (hoisting mechanisms, pumps) – D characteristic switches; Modular circuit breakers VA47-29 are recommended for use in electrical distribution panels of residential and public buildings.
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.
