ABB D2D146-AA02-22 AC Centrifugal Fan

Description

The D2D146-AA02-22 is a robust AC centrifugal fan manufactured by ABB, designed for high-performance cooling in industrial environments. This unit features a forward-curved, dual-intake design integrated into a durable housing with flange mounting, making it ideal for forced cooling of high-power converters, such as the ABB ACS800 drive series.

Features

• Forward-curved dual-intake centrifugal impeller for efficient airflow.
• Three-phase AC operation (230 VAC) with direction control via phase reversal.
• Integrated thermal overload protection (TOP) for motor safety.
• Compact, flange-mounted construction suitable for cabinet integration.
• Six-pin Molex connector (46992-0610) with PFA insulated wiring.
• High airflow capacity up to 1,600 m³/h at 50 Hz.

Applications

• Forced cooling for high-power industrial converters and drives.
• Control cabinet heat management to prevent thermal throttling.
• Industrial ventilation and air handling units (AHUs).
• Marine automation and power distribution panels.

Technical Specifications

Connections

• L1 (U1), L2 (V1), L3 (W1): Three-phase power input.
• PE: Protective Earth connection (Class I protection).
• TOP: Thermal Overload Protection lead.
• Connector: 6-pin Molex (Part 46992-0610) using 39-00-0059 socket contacts.

Installation Guidelines

• Mounting: Ensure the unit is securely flange-mounted to a rigid surface to minimize vibration.
• Electrical: Connect the protective earth (PE) wire immediately to ensure safety. Wire the motor according to the specific lead terminal markings.
• Operation: Forward-curved impellers can overload if operated in free-air conditions; maintain minimum back pressure (275 Pa at 50 Hz) during operation.
• Direction: Rotation direction can be reversed by swapping any two of the three phases.
• Handling: Always power down the system before inserting or removing the fan connector.

FAQs

What is the D2D146-AA02-22?
