Frequently Asked Questions

• What is the difference between heavy duty and normal duty ratings? Heavy duty (HD) rating — 7.5 kW / 16.5 A — is for applications with high overload cycles such as hoists or conveyors. Normal duty (ND) rating — 11 kW / 24 A — suits variable torque loads like pumps and fans with lower overload requirements.
• What supply voltage does the ATV340U75N4 accept? The drive accepts a three-phase supply of 380 to 480 V AC, covering standard European 400 V and North American 480 V industrial networks.
• Is an EMC filter built in? The ATV340U75N4 meets EN/IEC 61800-3 Category C2 (environment 1) and C3 (environment 2), confirming integrated or compatible EMC filter provision for both industrial and light industrial environments.
• What are the mounting requirements? The ATV340U75N4 is designed for cabinet mount installation in a control panel or enclosure. Dimensions are 110 mm W × 270 mm H × 234 mm D.
