Allen-Bradley 150-B360NBD Soft Start Controller is a Smart Motor Controller (SMC Dialog Plus) that provides soft-start and current-limiting control for three-phase motors, reducing inrush and mechanical stress during startup. It is rated for 360 A and supports a 200–480 V AC three-phase input with a 120–240 V AC control power supply, usable on standard 50/60 Hz power. As part of the SMC Dialog Plus family, it offers configurable start/stop behavior for reliable motor control in industrial applications where smooth acceleration and protection of electrical equipment are priorities.
