Line-side components -Recommended fuses Siemens

Обзор



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 > 800 A, this function is realized by the circuit breaker provided as standard.
In this case, a 3NA fuse can be used in the distribution system. If option L26 has not been selected for units < 800 A, then we strongly advise that 3NE fuses are used. 1)

Catalog LV 10.1 contains additional information on the fuses that have been listed.

1) The double function fuses (3NE1.) with duty class gS 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 flink

- coordinated to the I2t integral of the semiconductor

- lower arc voltage

- better current limiting (lower let-through I2t values)
