The Schneider Electric ATV71HD37N4 is a robust and efficient AC drive engineered for high-demand industrial motor control. With a rated motor power of 37 kW (50 HP), this drive is designed to handle complex applications involving variable torque and constant torque loads, such as pumps, compressors, conveyors, and process machinery.
Operating on a 3-phase line supply of 380–480 V, the ATV71HD37N4 can handle a maximum line current of 84 A at 380 V and 69 A at 480 V, allowing it to operate reliably across varying voltage conditions. Its apparent power rating of 55.7 kVA provides sufficient capacity for large motors and demanding mechanical systems.
This drive delivers exceptional overload handling capability, featuring a maximum nominal current (In) of 79 A, a transient current of 118.5 A for 60 seconds, and a peak transient current of 130 A for 2 seconds. These ratings ensure the ATV71HD37N4 can manage torque surges, startup demands, and load changes without loss of performance or overheating, even in harsh environments.
Safety and durability are core to its design. With a maximum prospective line short-circuit current (Isc) of 22 kA, it supports high-fault-level environments while protecting downstream equipment. Its heavy-duty rating and advanced thermal management system ensure long-term operation with reduced maintenance, which is ideal for industrial settings.
Designed as part of Schneider Electric's Altivar 71 series, the ATV71HD37N4 supports a broad range of communication protocols and configuration software, including Modbus, CANopen, Profibus, and Ethernet-based systems (with optional cards), enabling seamless integration into modern automation architectures.
