protection National regulations, the grid operator's specifications or other factors may
require a residual current circuit breaker in the AC connection lead.
For this situation, a type B residual-current circuit breaker is generally adequate.
However, false alarms can be triggered for the type B residual current circuit breaker in
individual cases and depending on local conditions. For this reason, in accordance with
national legislation, Fronius recommends that a residual current protection device with a
tripping current of at least 1000mA suitable for frequency converters be used.
NOTE!
The inverter can be used with max. an automatic circuit breaker 355 A.
