Siemens MICROMASTER MM400 VFD 4.0kW 380-480V 3-Phase 6SE6420-2UD24-0BA1

Siemens MM400 VFD 4.0kW – The Largest 380V MM400 Model

The Siemens MICROMASTER MM400, model 6SE6420-2UD24-0BA1, delivers 4.0kW output power – the maximum rating available with 380-480V input in the MM400 series. For higher power at 380V, consider the G120 series or other Siemens drive families.

- Output Power: 4.0kW (constant torque)
- Input Voltage: 380-480V AC 3-phase, 50/60Hz
- Rated Output Current: 9.2A
- Built-in Filter: Class B (enhanced filtering)
- Braking Transistor: Built-in
- Protection Class: IP20
- Operating Temperature: 0°C to 50°C
- Dimensions: 245mm × 185mm × 195mm
- Weight: 3.5kg

Typical Applications:
- Large industrial conveyors
- Industrial compressors (7.5-10 HP)
- Large mixing equipment
- Pump stations (multiple pumps)
- HVAC air handling units

Why This Model?
The 4.0kW model represents the power limit of the MM400 series at 380V input. For a manufacturing facility upgrading a 3.0kW conveyor system to handle heavier loads, this drive provided the necessary headroom without changing drive families or cabinet layouts.

Selection Guide:
Choose 4.0kW when your motor is rated 4.0kW at 380V. This is the last step before moving to the G120 series or other Siemens drive families. For 200V systems, the 5.5kW model (6SE6420-2UC25-5CA1) is available.

FAQ:

Q1: Why is there no 5.5kW 380V MM400 model?
A: MM400 series tops out at 4.0kW for 380-480V input. The 5.5kW model (2UC25-5CA1) uses 200-240V input. For 380V 5.5kW, consider Siemens G120 series or the next-generation drive families.

Q2: Can this drive handle 150% overload?
A: Yes, for 60 seconds. This allows the drive to handle short-term surges from starting heavy loads or temporary overload conditions.

Q3: What communication options are available?
A: Standard RS-485 Modbus RTU on terminals 14-15. Optional PROFIBUS module (6SE6400-1PB00-0AA0) and DeviceNet module (6SE6400-1DN00-0AA0) available as accessories.

Q4: How much clearance is required for installation?
A: 100mm above and below for airflow. 50mm on left and right for wiring access. For side-by-side mounting, no horizontal clearance is required.
