| Brand Name: | BM |
| Model Number: | YB3-280S-4 (B5) |
| MOQ: | 1 Piece |
| Price: | USD 2280 - 2790 / Piece |
| Packaging Details: | Plywood case with flange protection cover, moisture proof film and shock proof foam |
| Payment Terms: | T/T,L/C at sight,Western Union |
This YB3 series 75 kW, 4 pole explosion proof motor runs at 1500 r/min on a 400 V / 690 V supply and is supplied with an IM B5 flange so it can be bolted directly to close coupled pumps, gear units and skid mounted process equipment. The IE3 efficiency winding and Ex d IIC T4 Gb flameproof housing make it a drop-in replacement for ageing Ex motors in refineries, fuel depots and chemical plants.
