Allen-Bradley 150-A360NBD Three-Phase Magnetic Motor Starter

Allen-Bradley 150-A360NBD SMC Plus Soft Starter is an enclosed, non‑combination motor controller for three‑phase systems, rated to 360 A line current. It’s part of the SMC Dialog Plus family and comes in an IP30, Type 1 enclosure designed for indoor installation. The unit supports line voltages of 208 V, 480 V, and 600 V, with motor horsepower ratings shown as 150 HP at 208 V, 200 HP at 480 V, and 400 HP at 600 V, reflecting its high‑current capability across common industrial voltages. Control power requires a separate 100–240 V, 50/60 Hz single‑phase supply for the controller logic. By providing a soft‑start sequence, it limits motor inrush, reduces mechanical and electrical stress during startup, and helps protect connected equipment and the distribution network. This model is well suited for indoor, industrial applications where reliable, controlled starting of three‑phase motors and compact, integrated protection are key requirements.
