ξ3.
To ensure that the selected circuit breaker trips as expected, at minimum consider
the following:
The circuit breaker rated voltage.
Temperature de-rating due to both close proximity of other circuit breakers and
the effect of ambient temperature on the distribution board.
De-rating due to permanent load.
If the de-rated current of the selected circuit breaker is lower than the maximum output
current of the inverter, consider selecting a circuit breaker that is designed for a higher
rated current, or reducing the temperature de-rating effect by increasing the distance
between adjacent circuit breakers.
NOTE
Make sure to select cables that are suitable for the environmental
conditions, the operating voltage and the selected circuit breaker.
Three or four pole circuit breakers are required. It is recommended to use a
four pole circuit breaker when applicable.
Only use a circuit breaker with tripping characteristic B or C.
