Key Features
24V AC/DC Control Supply
The controller operates using a 24 V AC/DC control supply and supports a nominal 480 VAC three-phase main power circuit. This low-voltage control configuration is distinct from the 100-240 VAC control version.
Integrated Motor Bypass
The built-in bypass reduces thyristor conduction losses after motor acceleration, helping minimize steady-state power dissipation and heat generation during the applicable running condition.
Adjustable Starting and Soft Stopping
Selectable current limits of 150-450% of motor full-load current, start times from 2 to 30 seconds, initial torque settings and configurable soft stopping support different mechanical load requirements.
Integrated Overload Protection
Electronic motor overload protection with selectable Class 10, 15 and 20 trip characteristics helps protect compatible motors. A normally open fault contact provides an interface for supported alarm and control circuits.
Compact IP2X Construction
The open-type controller measures 206 × 72 × 130 mm, weighs 2.25 kg and has an IP2X protection rating. Documented steady-state heat dissipation is 34 W.
Applications
- Industrial three-phase induction motor soft starting
- Conveyor and material handling equipment
- Centrifugal pump motor starting and stopping
- Industrial ventilation fans and blowers
- Packaging and manufacturing machinery
- Motor control cabinets using 24V AC/DC control circuits
- Industrial mechanical equipment requiring controlled acceleration
- SMC-3 motor starter maintenance and replacement

Frequently Asked Questions
What is Allen-Bradley 150-C43NBR?
Allen-Bradley 150-C43NBR is a Bulletin 150-C SMC-3 solid-state soft starter rated at 43 A, with a nominal 480 VAC three-phase main power supply and a 24 V AC/DC control supply.
What is the current rating of 150-C43NBR?
The controller is rated at 43 A. Rockwell Automation specifies a line-connected motor current range of 14.3-43 A for supported 380/400/415/460 VAC installations.
What control voltage does 150-C43NBR require?
This model requires 24 V AC/DC control power. The documented control current during starting is 700 mA with the fan operating.
What is the difference between 150-C43NBR and 150-C43NBD?
The 150-C43NBR uses 24 V AC/DC control power, while the 150-C43NBD uses 100-240 VAC control power. The control supply must match the installation before selecting either model.
What motor power range does 150-C43NBR support?
Manufacturer selection data identifies 10-30 HP for line-connected motors at 460 VAC under the stated starting-duty conditions. Motor current, start frequency and load characteristics must also be considered.
Does 150-C43NBR support inside-delta connections?
Yes. Rockwell Automation specifies an inside-delta motor current range of 25-74 A for the applicable 380/400/415/460 VAC operating conditions. Motor wiring must follow the installation instructions.
Does 150-C43NBR include an internal bypass?
Yes. The module has an integrated bypass to reduce power losses during the applicable full-speed operating condition.
What current limit settings are available?
The controller supports selectable current limits of 150%, 250%, 350% and 450% of motor full-load current, along with configurable starting time and initial torque.
Does 150-C43NBR include electronic overload protection?
Yes. Integrated motor overload protection provides selectable Class 10, 15 and 20 trip settings. The protection settings must be selected for the motor and application.
Can 150-C43NBR perform soft stopping?
Yes. Soft stopping can be disabled or set to 100%, 200% or 300% of the selected starting time when the controller is wired and configured appropriately.
Does 150-C43NBR include a display or fault contact?
The controller has no 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-C43NBR?
Verify the manufacturer catalog number 150-C43NBR, 43 A controller rating, main supply voltage, 24 V AC/DC control power, motor nameplate current, line or inside-delta wiring, overload trip class, starting characteristics, fault contact wiring, IP2X protection and 206 × 72 × 130 mm installation dimensions.
