Product Analysis: ATV71HD30N4
The Schneider Electric ATV71HD30N4 is a heavy-duty **Variable Frequency Drive (VFD)** from the legendary **Altivar 71** series. Rated for **30 kW (40 HP)** motors, it is designed for complex constant torque applications requiring precise speed regulation and high torque at low speeds.
Performance Data
- Power Rating: 30 kW / 40 HP.
- Input Voltage: 380…480 V AC (3-Phase).
- Current: 66 A (Continuous).
- Overload: 170% for 60 seconds.
Legacy Application
Although the ATV71 series has been superseded by the ATV900, the **ATV71HD30N4** remains critical for existing installations in hoisting, elevators, and centrifuges. Replacing a failed ATV71 with the exact same part number avoids the need to redesign the control cabinet or rewrite Profibus/Modbus communication telegrams.
