Product Description

YB3-250M-4 55 kW 4 Pole Flameproof Asynchronous Motor

The BM YB3-250M-4 delivers 55 kW at 4 pole in a compact 250M cast iron frame, which makes it the usual choice where a 75 kW motor would not fit on an existing conveyor or pump base. The Ex d IIC T4 Gb flameproof enclosure and IP55 sealing allow continuous duty in coal preparation plants, fuel depots and chemical workshops classified as Zone 1 or Zone 2.

Key Features

55 kW, 4 pole, 1480 r/min, S1 continuous duty for conveyor and pump loads
Compact 250M frame keeps the IEC footprint of the previous 55 kW unit
Ex d IIC T4 Gb flameproof enclosure for gas groups IIA, IIB and IIC
IE3 level efficiency (93.5 %) meets EU Ecodesign and cuts running cost
IP55 cast iron frame with IC411 fan cooling for dusty coal and cement areas
Class F insulation with Class B temperature rise for long winding life
Dual voltage 380 V / 660 V winding supports Y-Δ starting
PTC thermistor, space heater and B5 flange available on request

FAQ

Q: Can you supply the complete 4 pole power range?
A: Yes. Our YB3 flameproof range covers 55 kW, 75 kW, 90 kW, 110 kW and 132 kW at 4 pole from stock or short production runs.

Q: Are the mounting dimensions interchangeable with old YB2 or YBX motors?
A: Yes. IEC frame dimensions follow the standard Y series footprint, so the motor usually replaces an ageing unit without base modification.

Q: What certificates come with the motor?
A: ATEX 2014/34/EU certificate copy, CNEx certificate, routine test report and outline drawing are supplied with every shipment.

Q: What is your lead time?
A: 15 to 25 working days after deposit, depending on power rating and voltage configuration.
