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 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

Applies to industrial control panel installations acc. to NECВ articleВ 409 or ULВ 61800-5-1.

• PM240P-2: 65В kA

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/600В V (phase-phase), 480В V/600В V (phase-ground) at a rated line voltage of 480В V/600В V
• Voltage limit 4В 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 is available in Catalogs LVВ 10, ICВ 10 and ICВ 10В 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).
