Product Description

YB3-280S-4 75 kW 4 Pole Flameproof Asynchronous Motor

The BM YB3-280S-4 is a 75 kW, 4 pole three phase asynchronous motor built in a cast iron flameproof enclosure for Zone 1 and Zone 2 hazardous areas. The Ex d IIC T4 Gb design contains any internal spark or flame inside the explosion proof housing, so the motor can drive pumps, fans and compressors in petrochemical plants, refineries and coal preparation lines without becoming an ignition source.

Key Features

Ex d IIC T4 Gb flameproof enclosure, suitable for gases in groups IIA, IIB and IIC including hydrogen and acetylene
75 kW continuous S1 duty with 1480 r/min rated speed at 50 Hz
IE3 level efficiency (94.4 %) lowers running cost over a 10 year service life
IP55 cast iron frame with IC411 totally enclosed fan cooling for dusty and humid workshops
Class F insulation with Class B temperature rise gives 20 K thermal margin
B3 foot mounted design fits standard IEC pump, fan and gearbox bases
Wide voltage 380 V / 660 V winding, Y-Δ start supported
PTC thermistors and anti-condensation heaters available on request
