Note for use in compliance with IEC standards:

Type 3NA3 fuses and type 3RV circuit breakers are recommended for European countries. The values in the table take into account the overload capability of the inverter.

Notes for use in compliance with UL regulations:

Fuses for use in North America must be UL-certified, class J, T, CC, G or CF fuses with a rated voltage of 600В VВ AC.

Short Circuit Current Rating (SCCR)
according to UL

Applies to industrial control panel installations to NEC Article 409 or UL 508A.

• SINAMICSВ G120C: 100В kA (the value depends on the fuses and circuit breakers used)

Notes regarding installations in Canada:

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

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

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