MC07B0040-5A3-4-00 Variable Frequency Drive MC07 4.0kW 3-ф/380

MC07B0040-5A3-4-00 — SEW MOVITRAC B rated 4 kW, 3х380 В supply, rated current 9.5 A. A basic SEW inverter with U/f control and VFC sensorless vector mode, up to 150% IN short-term overload. It is mostly chosen for SEW geared motors — as a native replacement or a line extension.

Typical uses:

• Industrial pump or fan
• Conveyor on a SEW gearmotor
• Mixer, small extruder, compressor

Note: On this frame the EMC filter is, as a rule, already integrated — but verify the configuration for the exact code. Modbus/PROFIBUS/EtherCAT are added as a separate module.

If this is a new job with no SEW tie-in, compare it with our in-stock Veichi with on-board Modbus. Unsure about the replacement frame — send us the nameplate number.

SEW MOVITRAC B (MC07) — standard inverter built around SEW geared motors

MOVITRAC B is the basic, economy tier of SEW-Eurodrive's drive range. A plain, dependable inverter with no excess: U/f control plus VFC sensorless vector mode, with up to 150% IN short-term and up to 125% IN continuous overload. People usually choose it where SEW geared motors are already installed and they need a like-for-like replacement or an extension of the same line. The range here spans 0.75 to 75 kW.

In our experience MC07B is not a "universal stock inverter" but a drive tied to the SEW ecosystem. If your conveyor, doser or agitator runs on a SEW gearmotor, MOVITRAC B fits natively by mounting, parameters and service. For a new site with no SEW lock-in it is often smarter to take our in-stock Veichi variable frequency drive — more on that below, honestly.

What MOVITRAC B suits

• Materials handling: roller tables, belt and bottle conveyors, rotary tables — MC07B's home turf alongside SEW gearmotors.
• Pumps and fans: booster pumps, supply/exhaust ventilation — VFC mode holds torque without an encoder.
• Dosers, mixers, turntables: simple drives where the built-in IPOS positioning and sequence control earns its keep.
• Single-phase 230 V supply: for workshops and sites without three-phase — but only up to 2.2 kW, which is the single-phase ceiling for MC07B.

Worth knowing before you buy

SEW typically builds the integrated EMC filter into the smaller frames (roughly up to 11 kW). On the larger 3-phase frames the filter is often a separate item — check the configuration of your specific MC07B so you pass EMC on site. Fieldbus (PROFIBUS, CANopen, EtherCAT, Modbus, PROFINET) on MOVITRAC B is mostly delivered through plug-in gateway modules rather than on-board. A braking resistor/chopper is, as a rule, also a separate line item — budget for it up front.

MOVITRAC B or Veichi — short and honest

The takeaway is simple: for existing SEW equipment, take MOVITRAC B — less hassle on replacement and service. For a new pump, fan or conveyor with no SEW tie-in, our Veichi is usually the better value: Modbus right away, built-in PID on AC310, and delivery from stock.

When MOVITRAC B is NOT the right pick

• You need Modbus RTU for SCADA without buying a gateway — look at Veichi AC310.
• A single-phase job above 2.2 kW — there is no higher single-phase MC07B, you need a three-phase supply.
• Above 75 kW or heavy crane duty beyond the MOVITRAC B band — that is MOVIDRIVE or a heavy-duty inverter class.

If you are unsure which MC07B replaces your old SEW unit, send us the number from the nameplate and we will confirm the exact frame and whether an external filter is needed.
