Buying Guide

• Check your supply voltage. This motor is 400 V, 50 Hz.
• Confirm mounting. IM B35 is standard. Measure your flange pattern.
• Match speed. 1464 min⁻¹ is 4-pole at 50 Hz.
• Consider inverter use. Add a VFD for speed control.
• Verify duty cycle. S1 continuous is for constant loads.
• Check ambient conditions. IP55 is fine for most factories.
• Order spare fuses and contactors rated for 7.9 A.
• For outdoor use, add a rain shield or upgrade to IP66.
