55 kW VFD: what jobs we ship it for

55 kW units we ship for 55 kW 380 V motors with nominal current around 105-110 A. Typical customer this year: trunk water supply pumps for city utilities. Screw compressors 10 m³/min at cement and woodworking plants. Aspiration at 1000+ t grain elevators. Raw-material crushers in foundries. Traction drives on test rigs. On 45 kW these jobs trip on overload: a compressor with 280-300 A inrush exceeds the IGBT limit.

From the grid: 3-phase 380 V, the 660 V option exists for mining and heavy industry (INVT GD350-055G-6). Rated draw 110 A, breaker 160 A C-curve, cable 50 mm² copper up to 30 m. Veichi AC70-T3-055G/075P per datasheet holds 150% for 60 s (G mode, crushers) and 110% continuously (P mode, pumps). INVT GD200A-055G/075P the same plus on-board PLC functions; for simple sites you can skip a separate controller.

Which model we ship most often

From main stock: Veichi AC70-T3-055G/075P (mid-tier, our top product in this band, in stock monthly). INVT GD200A-055G/075P (European feature equivalent with built-in PLC). Schneider ATV212HD55N4 when the customer asks for Europe with basic HVAC functionality. Schneider ATV630, ATV930 for premium HVAC and complex industrial jobs. Delta VFD550C43A: ship to order from Taiwan warehouse 7-14 days. ABB ACS880-01-105A-3 we ship only when the site is already on ABB. Veichi SI23-T3-055G-A (solarized, MPPT 200-820 V) we ship for 55 kW solar pump stations.

Before paying we ask. First: load type G or P? Crusher, compressor, shock-load conveyor (G); pump or fan (P). This decides 55 kW in G or 45 kW in P. Second: braking resistor. For a 55 kW centrifuge the BR draws 14-18 kW; without it OU within 0.6 s. Third: cable length. Over 30 m a du/dt filter is required; over 100 m a sine filter. Fourth: ambient IP. Base drive is IP20; for dusty production we ship in a separate IP54 cabinet. 2-year warranty, 1-3 day delivery from our Kyiv warehouse.

Frequently Asked Questions

Which motor is a 55 kW VFD selected for?

A 55 kW VFD is selected for a three-phase electric motor with a rated power of 55 kW when the motor current does not exceed the drive rated current. Before ordering, check the motor nameplate: power, voltage, current, and wiring diagram.

What input voltage is required for a 55 kW VFD?

The input voltage depends on the site supply and the motor. For a single-phase 220 V supply, choose a 220 V input model if it is available for this power. Industrial motors usually require a 3-phase 380 V VFD.

Do I need extra power reserve for a 55 kW VFD?

For pumps and fans, selecting by the motor rated power and current is often enough. For heavy starts, conveyors, compressors, mixers, or frequent acceleration cycles, allow extra current reserve or move to the next power size.

Where are 55 kW VFDs used?

55 kW VFDs are used to control the speed of pumps, fans, conveyors, machines, and other equipment with asynchronous motors. The exact application depends on load torque, duty cycle, and installation conditions.

How can I quickly choose the right model?

Send a motor nameplate photo or provide the power, voltage, rated current, number of phases, and load type. A Chastotnik.ua manager will select a compatible VFD, check availability, and advise on basic startup parameters.
