Schneider ATV310HU75N4A Variable Speed Drive

Product Introduction

The Schneider ATV310HU75N4A Variable Speed Drive is part of the Easy Altivar 310 series, designed for speed control of three-phase asynchronous motors in standard industrial environments. It supports a rated power of 7.5 kW (10 HP) in heavy-duty operation and up to 11 kW (15 HP) in normal-duty operation, with a rated supply voltage range of 380–460 V AC.

The drive features an IP20 protection level, a compact yet robust mechanical structure, and an integrated functional design. Based on a plug-and-play operating concept, it allows fast commissioning while maintaining stable motor control performance. The ATV310HU75N4A is particularly suitable for industrial machinery as well as selected equipment used in semi-industrial or consumer-oriented applications.

Its integrated control functions cover the most common motion control requirements, making it well adapted for textile machines, machine tools, woodworking equipment, material handling systems, packaging and printing machinery, and ceramic machines.
