Recommended line-side power components

Обзор

Selection and ordering data

The following table lists recommendations for additional line-side components, such as fuses and circuit breakers. The values in the table take into account the overload capability of the inverter.

Notes for use in compliance with IEC standards:

3NA3 or 3NE1 fuses and 3RV motor starter protectors or 3VL circuit breakers are recommended for European countries.

Notes for use in compliance with UL regulations:

UL-listed fuses Class J or 3NE1 with 600 V AC rated voltage (UL-compliant – corresponds to RU) are required for North America.

Short Circuit Current Rating SCCR

Short Circuit Current Rating according to UL

Valid for the use in NEC Article 409 oder UL 508A/508C compliant industrial control cabinets

• PM240: 65 kA

Notes regarding installations in Canada:

Overvoltage protection devices in accordance with overvoltage category III and with the following ratings must be connected on the line side of the inverter:

• Rated voltage 480 V (phase-phase) and 480 V (phase-ground)
• Voltage limit 4 kV (phase-phase) and 6 kV (phase-ground)

All overvoltage protection devices used must comply with Canadian standards for industrial installations.

Additional information about the listed fuses and circuit breakers can be found in Catalogs LV 10.1, IC 10 and IC 10 AO.

¹⁾ Rated power based on the rated output current I_rated. The rated output current I_rated is based on the duty cycle for low overload (LO).
