4. Main technical parameters
4.1 Main technical parameters
4.2 Capacity-reducing usage
4.2.1 Capacity-reducing at different temperatures
The following table shows the continual current-loading capacity of the circuit breakers and buses in each wiring mode at the
corresponding ambient environment temperatures and under the conditions of the satisfaction of conventional heating with a
similarity in capacity reducing between the breaker connected in a mixed way and the breaker connected horizontally.
4.2.2 Capacity-reducing at different altitudes
When the altitude is higher than 2000m, there will appear changes in insulation property, cooling performance, pressure,and the
performance can be modified in reference to the following table.
4.3 Power loss
Power loss is the loss at each pole which is measured when the breaker is charged with the rated current.
Note: The data and parameters in the above technical documentation results from tests and theoretical calculation,
and can only be used as a general type selection guide.They cannot replace industrial practical experience or proof test.
5.4 Recommended bus for the breaker and recommendation for users to install the buses
