ABB ACS550 Ratings, Types and Voltages

ACS550 – 01 – 03A3 – 4 + B055

Type Code

This is the unique reference number (shown above and in column 7) that clearly identifies your drive by power rating and frame size. Once you have selected the type code, the frame size (column 8) can be used to determine the drives dimensions.

Voltages

The ACS550 is available in two voltage ranges:

• 4 = 380 – 480 V
• 2 = 208 – 240 V

Insert either ‘4’ or ‘2’ depending on your chosen voltage, into the type code shown above.

Normal use vs heavy-duty use.  For the majority of pump, fan and conveyor applications, select ‘normal use’ figures. For high overload requirements, select ‘heavy-duty use’ figures.

• Pn for kW = Typical motor power in 400 V at normal use
• Pn for hp = Typical motor power in 460 V at normal use
• Phd for kW = Typical motor power in 400 V at heavy-duty use
• Phd for hp = Typical motor power in 460 V at heavy-duty use
