About the Allen-Bradley 150-F361NBD

The 150-F361NBD is an SMC Flex smart motor controller, a three pole soft starter with single direction function, rated 361 A, 150-300Hp @ 460V AC. Control voltage is 100...240V AC, and the power circuit is rated 200...480V AC, with a line connected motor current of 120...361 A @ 600/Y/690V AC, 3-phase. The open type unit measures 600 mm high, 290 mm wide and 276.5 mm deep, and weighs 45.8 kg.

What is the 150-F361NBD used for?

It starts and stops a three phase motor smoothly, limiting the current and torque surge of a direct start. It has integrated motor overload protection, an internal bypass, and status indication for stopped, starting, stopping, at speed, alarm and fault. The optional SMB smart motor braking control brakes the motor without additional equipment.
