About ATV340D37N4E - ATV340, 37 kW Heavy Duty, 400 V, 3 phases, Ethernet

The

ATV340D37N4E

is the 37 kW (50 HP) version of the Schneider Electric Altivar Machine 340 series, featuring embedded Ethernet connectivity. It provides the same advanced control functions as the 30 kW model but with a higher current capacity for more demanding 3-phase asynchronous and synchronous motors.

Key Specifications

Power Rating: 37 kW (50 HP) for heavy-duty; up to 45 kW (60 HP) for normal-duty applications.
Voltage: 3-phase, 380V to 480V AC.
Current Rating: 74.5 A (Heavy Duty) and 88 A (Normal Duty).
Safety Features: Integrated Safe Torque Off (STO), Safe Stop 1 (SS1), and Safely Limited Speed (SLS).
Communications: Integrated dual-port Ethernet (EtherNet/IP and Modbus TCP) plus Modbus Serial.
Protection Rating: IP20 with integrated Class C3 EMC filter.

Design & Dimensions

This model uses the same frame size as the 30 kW unit, requiring substantial cabinet space and forced convection for cooling.

Width: 8.39 in (213 mm)
Height: 25.98 in (660 mm)
Depth: 10.31 in (262 mm)
Weight: ~62.6 lbs (28.4 kg)

The ATV340D37N4E functions as the high-capacity control engine for motors up to 37 kW (50 HP). While its software features are identical to the 30 kW model, its physical "Function" is expanded to handle an even higher continuous current of 74.5 Amps.

1. High-Current Load Control

Massive Torque Delivery: At 37 kW, this drive functions to control high-inertia machinery such as industrial crushers, heavy extruders, and large-scale wastewater pumps. It provides 150%180% nominal torque for 2 seconds to get these massive loads moving.
Normal Duty Capability: It can be configured for "Normal Duty" to run a 45 kW (60 HP) motor (up to 88 Amps) for applications like large fans or centrifugal pumps where high starting torque isn't required.

2. Advanced Communication & IoT (The "E" Feature)

Real-Time Data Hub: The dual Ethernet ports function as a high-speed gateway, allowing the drive to report high-resolution data (amps, torque, thermal state) to an Edge Box or Cloud system for predictive maintenance.
Synchronized Motion: It is designed to function within a multiaxis system. If you have three or four 50 HP motors that must move in perfect sync, the Ethernet capability ensures they communicate with the PLC with microsecond precision.

3. Electrical & Thermal Management

Harmonic Reduction: Like the 30 kW model, it includes a built-in DC Choke. This functions to clean up the electrical "noise" that a 74.5A load would otherwise dump back into your factory's power grid.
Forced Cooling: Because it dissipates significant heat (nearly 1,000 Watts at full load), its internal fans are high-performance. It functions to protect itself by monitoring its own internal temperature and the motor's temperature simultaneously.

4. Safety & Braking

Regenerative Braking: Includes a high-power built-in braking transistor. For a 50 HP motor, this is critical for stopping heavy rotating masses quickly without causing an "Overvoltage" fault.
SIL3 Safety: It provides the highest level of integrated safety (STO, SS1, SLS), meaning you can safely stop a 37 kW motor without needing bulky and expensive external safety contactors.
