>> Introduction
BA47-29 are intended for protecting distribution and group systems having different loads:
- electric appliances, lighting – V characteristic switches;
- drives with moderate starting currents (compressor, fan group) - C characteristic switches;
- drives with high starting currents (hoisting mechanisms, pumps) - D characteristic switches;
Miniature circuit breaker BA47-29 are recommended for use in electrical distribution panels of residential and public buildings.
>> Advantages
· Two types of short circuit protection.
· Wide range of operating temperatures from –40 to +50° С.
· Updated wider engagement lever with improved contact area.
· Notches on terminal clamps provide for lowering thermal losses and boosting the mechanical stability of connection.
