The Allen-Bradley SMC-3 150-C30NBD provides a 30 A controller current rating for compatible three-phase induction motors, with a documented line-connected motor current range of 10-30 A at specified supply voltages.
The controller uses a 100-240 VAC control supply and supports a nominal 480 VAC three-phase main power circuit. This configuration differs from the 24 V AC/DC control version.
The internal bypass reduces thyristor conduction losses after motor acceleration, helping minimize heat generation and energy losses during the applicable running condition.
Selectable current limits of 150-450% of motor full-load current, starting times from 2 to 30 seconds, adjustable initial torque, kick-start settings and configurable soft stopping support different mechanical load requirements.
The SMC-3 provides integrated electronic overload protection with selectable Class 10, 15 and 20 trip characteristics. A normally open overload/fault auxiliary contact supports compatible monitoring circuits.
The open-type controller measures 139.7 × 44.8 × 110 mm and weighs approximately 0.86 kg. It has an IP2X protection rating and documented steady-state heat dissipation of 19 W.

What is Allen-Bradley 150-C30NBD?
Allen-Bradley 150-C30NBD is a Bulletin 150-C SMC-3 solid-state soft starter rated at 30 A, designed for three-phase motor starting with a nominal 480 VAC main power voltage and 100-240 VAC control power.
What is the rated current of 150-C30NBD?
The controller has a 30 A current rating. Rockwell Automation specifies a line-connected motor current range of 10-30 A for compatible 380/400/415/460 VAC installations.
What control voltage does 150-C30NBD require?
This model requires 100-240 VAC control power. The documented current during starting with the fan operating is 215 mA at 120 VAC or 180 mA at 240 VAC.
What is the difference between 150-C30NBD and 150-C30NBR?
The 150-C30NBD uses 100-240 VAC control power, while the 150-C30NBR uses 24 V AC/DC control power. These versions are not directly interchangeable unless the available control supply is compatible.
What motor horsepower range does 150-C30NBD support?
The manufacturer specifies 7.5-20 HP for line-connected motors at 460 VAC and 7.5-30 HP for compatible inside-delta motor connections at 460 VAC. Actual selection depends on motor current and starting conditions.
Does 150-C30NBD support inside-delta connections?
Yes. Rockwell Automation documents an inside-delta motor current range of 17.3-52 A at the applicable 380/400/415/460 VAC supply voltages. Wiring and circuit protection must meet manufacturer requirements.
Does 150-C30NBD include an internal bypass?
Yes. The controller includes an integrated bypass that reduces power losses during the applicable full-speed motor running condition.
What current limit settings are available?
The available current limit settings are 150%, 250%, 350% and 450% of motor full-load current. Starting time, initial torque and kick-start duration are also configurable.
Does 150-C30NBD include electronic motor overload protection?
Yes. The starter provides integrated electronic motor overload protection with selectable Class 10, 15 and 20 trip settings. The overload configuration must match the connected motor and application requirements.
Can 150-C30NBD perform soft stopping?
Yes. Soft stopping can be disabled or configured to 100%, 200% or 300% of the selected starting time when the controller is wired and configured appropriately.
Does 150-C30NBD include a display or fault contact?
The module does not include an integrated display. It provides one normally open overload/fault auxiliary contact at terminals 97-98, rated at 0.6 A at 120 VAC or 0.3 A at 240 VAC.
What should be checked before ordering 150-C30NBD?
Verify the manufacturer catalog number 150-C30NBD, 30 A controller rating, three-phase main supply voltage, 100-240 VAC control supply, motor full-load current, line or inside-delta wiring, overload trip class, starting settings, fault contact connections, IP2X protection and 139.7 × 44.8 × 110 mm installation dimensions.
