ABB Bailey IEFAN03 – Cooling Fan Assembly for Control Cabinets

The ABB Bailey IEFAN03 provides forced-air cooling for densely packed electronic enclosures. This fan assembly measures 120 mm in length and 120 mm in width. It has a depth of 38 mm, so it fits standard panel cutouts easily. The unit weighs 0.35 kg, making installation lightweight and simple.

Internal Components and Airflow Design

This cooling assembly contains two main parts inside its plastic housing. One part is a brushless DC motor with an integrated impeller. The other part is a removable dust filter for field cleaning. The ABB Bailey IEFAN03 moves air at a rate of 65 cubic feet per minute. It achieves this airflow while spinning at 2800 revolutions per minute.

Power Requirements and Electrical Interface

You will find a pre-wired 2-pin connector on the fan’s output cable. This connector accepts 24V DC with a tolerance of ±10 percent. The fan draws only 180 mA under normal operating conditions. Therefore, total power consumption stays at 4.32 watts during continuous use. The assembly stores no electrical energy internally for safety reasons.

Durability and Environmental Tolerance

The ABB Bailey IEFAN03 uses dual ball bearings for extended mechanical life. These bearings support 50,000 operating hours at room temperature. You can run this fan in ambient temperatures from -10°C to +60°C. The device also tolerates relative humidity levels up to 95 percent without condensation.

Mounting and Maintenance Features

You can mount this assembly using four M3 screws through its corner holes. The front grille includes a finger guard for technician safety. A reusable foam filter traps airborne dust before it enters your cabinet. You should clean this filter every three months for optimal airflow.

Below is a complete summary of its technical specifications.

The ABB Bailey IEFAN03 replaces older fan trays in Bailey control systems seamlessly. You do not need any adapter plates or additional wiring harnesses. This assembly also works as a standalone cooling unit for third-party enclosures. Consequently, it keeps sensitive electronics within safe operating temperatures year-round.
