Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Ac Motors. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
The IE3-280S-4 is a three-phase, four-pole squirrel-cage AC induction motor intended for industrial driving duties. The supplied product data identifies it as an IE3 model with low-speed classification, variable-frequency starting, and 50 Hz or 60 Hz operation.
Listed enclosure protection options are IP54, IP55, and IP56, while the available insulation classes are B, F, and H. The casing is described as explosion-proof, with IIA, IIB, and IIC classifications listed as options.
For the broader IE3 motor series, the stated range covers 0.75-355 kW outputs, 2-, 4-, 6-, and 8-pole configurations, and nominal speeds from 750 to 3600 rpm. Aluminum frames are listed in sizes 80-160 and cast-iron frames in sizes 80-400.
Cooling arrangements include IC411 and IC416, with S1, S2, and S3 duty types and IP55, IP56, IP65, or IP66 protection options. These are series-level ranges and should not be assumed to describe the exact IE3-280S-4 configuration without confirmation.
Procurement questions to confirm: Buyers should request the exact rated output, rated voltage, full-load speed, current, efficiency, power factor, mounting arrangement, frame material, cooling method, duty type, and dimensional drawing for the offered unit.
The required hazardous-area classification and its supporting motor-specific documentation should also be verified. Confirm whether the selected configuration carries any required CE, UL, ISO, or IEC documentation rather than relying on the general listing title.
Buyers should additionally confirm included accessories, terminal-box orientation, variable-frequency-drive operating limits, customization scope, packing dimensions, gross weight, production lead time, inspection requirements, and warranty terms before ordering.
