Notes 1)Rated operational current based on the load cycle specified here.
2)Indicates the circuit-breaker required for the indicated load cycle. At different duty cycles (operating frequency, overcurrent, overcurrent time,
duty factor), this value changes and must then be adapted accordingly.
3) An external overload relay is required if the main contacts are not to be disconnected in the event of an overload and a controlled soft stop is
desired instead.
4)A mains contactor is not required. Disconnection characteristics in accordance with VDE can only be ensured with the specified circuit-breaker.
5)The superfast semiconductor fuses protect the soft starters from motor-side short-circuits. This can not, however, prevent damage caused by
voltage peaks, for example through lightning strike.
