The fuses specified below are the recommended types for protecting the unit on the low-voltage distribution panel. If option L26 was selected for SINAMICS S150 with rated input currents <800 A, then the semiconductor protection is already integrated in the unit. For units of >800 A, this function is performed by the circuit breaker provided as standard.
In this case, a 3NA fuse can be used in the distribution board. If option L26 has not been selected for units <800 A, we strongly advise that 3NE fuses are used 1). Catalog LV 10 contains additional information on the listed fuses. Type rating

1) The double function fuses (3NE1.) for cable and semiconductor protection are recommended to protect the converter. These fuses are specially adapted to the requirements of the semiconductors in the input rectifier. - Super fast - Lower arc voltage - Improved current limiting (lower let-through values).
