Key Features
24V AC/DC Control Supply
The controller uses 24 V AC/DC control power, making it suitable for industrial motor control systems designed around low-voltage control circuits. This configuration differs from 100-240 VAC control variants.
Integrated Bypass
The built-in bypass reduces thyristor conduction losses after motor acceleration, helping limit steady-state heat generation in compatible motor starting applications.
Configurable Starting Performance
Selectable current limits of 150-450% of motor full-load current, starting times from 2 to 30 seconds and adjustable initial torque provide flexibility for different motor loads.
Built-In Motor Overload Protection
The SMC-3 includes motor overload protection with selectable Class 10, 15 and 20 trip characteristics, along with a normally open overload/fault auxiliary contact.
Compact Industrial Construction
The open-type IP2X controller measures 206 × 72 × 130 mm and weighs 2.25 kg, with documented operation from -5°C to 50°C.
Applications
- Industrial three-phase induction motor soft starting
- Conveyor and material handling systems
- Centrifugal pump motor starting and stopping
- Industrial fan and blower starting systems
- Manufacturing and processing machinery
- Motor control cabinets using 24V AC/DC control power
- Mechanical equipment requiring reduced starting current
- Industrial motor starter maintenance and replacement

Frequently Asked Questions
What is Allen-Bradley 150-C85NBR?
Allen-Bradley 150-C85NBR is an SMC-3 solid-state soft starter rated at 85 A, designed for three-phase motor applications with a 480 VAC voltage class and 24 V AC/DC control supply.
What is the rated current of 150-C85NBR?
The controller is rated at 85 A. Rockwell Automation specifies a line-connected motor current range of 28.3-85 A for the documented 380-460 VAC applications.
What control voltage does 150-C85NBR require?
This model requires 24 V AC/DC control power. The manufacturer specifies approximately 700 mA control current during starting with the fan operating.
What is the difference between 150-C85NBR and 150-C85NBD?
Both models belong to the 85 A SMC-3 family, but the 150-C85NBR uses 24 V AC/DC control power, while the 150-C85NBD is the 100-240 VAC control supply configuration. They should not be substituted without confirming the available control voltage.
What motor power does 150-C85NBR support?
The documented line-connected motor range at 460 VAC is 25-60 HP. Inside-delta configurations have a documented range of 25-100 HP at 460 VAC. Actual selection depends on motor current and starting duty.
Does 150-C85NBR support inside-delta motor connections?
Yes. Rockwell Automation specifies an inside-delta motor current range of 50-147 A under the applicable voltage conditions. Wiring and controller sizing must follow the manufacturer instructions.
Does 150-C85NBR have an internal bypass?
Yes. The controller includes an integrated bypass to reduce power losses during the applicable full-speed operating condition.
What starting current limits are available?
Selectable current limits are 150%, 250%, 350% and 450% of motor full-load current. Start time and initial torque settings are also adjustable.
Does 150-C85NBR provide motor overload protection?
Yes. The starter includes integrated motor overload protection with selectable trip classes 10, 15 and 20. Protection settings must be selected using the motor nameplate and applicable installation requirements.
Does 150-C85NBR include a display or auxiliary contact?
The controller does not include an integrated display. It provides a normally open overload/fault auxiliary contact at terminals 97-98 for supported indication circuits.
What are the dimensions and protection rating?
The product dimensions are 206 × 72 × 130 mm, measured as height, width and depth. It weighs 2.25 kg and uses an open-type construction with IP2X protection.
What should be checked before ordering 150-C85NBR?
Verify the exact catalog number 150-C85NBR, 85 A controller rating, supply voltage, 24 V AC/DC control supply, line or inside-delta motor connection, motor full-load current, overload trip class, starting duty, enclosure requirements, terminal connections and installation dimensions against the existing equipment documentation.
