R3G500-RA25-01 ebmpapst 400V EC Centrifugal Fan

Description

The ebmpapst R3G500-RA25-01 is a high-performance EC centrifugal fan with an external rotor motor, measuring Ø500mm in size. This 3-phase fan operates at a nominal voltage of 400VAC within a broad range of 380-480VAC, and is suitable for both 50Hz and 60Hz frequencies. It consistently achieves a speed of 1700RPM, consumes 2650W of power, and draws 4.4A of current. The fan features robust ball bearings and has an impeller made of PP plastic with 9 blades, and a coated in black rotor surface. The electronics housing is constructed from die-cast aluminium.

The R3G500-RA25-01 boasts an IP54 type of protection, insulation class “F”, and Humidity class F4-1. It includes integrated technical features such as an integrated PID controller, passive PFC, soft start, motor current limit, and various outputs/inputs (e.g., 0-10VDC, 4-20mA for sensor input), and an alarm relay. Comprehensive motor protection includes reverse polarity and locked-rotor protection, over temperature protected electronics/motor, and line undervoltage/phase failure detection. Electrical connection is via a terminal box. The fan operates in S1 mode within an ambient temperature range of -25°C to 60°C, with transport/storage temperatures between -40°C and +80°C. Its mounting position can be shaft horizontal or rotor on bottom (rotor on top on request), and it features rotor-side condensate drainage holes. Conforming to EN 61000-6-1, it holds approvals including UL 1004-7 + 80730, EAC, C22.2 Nr.77, and CAN/CSA-E60730-1. This fan is suitable for industrial refrigeration and freezing equipment, ventilation systems, air conditioning units, and heat pumps.
