Key Features
24V AC/DC Control Supply
The controller operates using 24 V AC/DC control power and supports a nominal 480 VAC three-phase main power circuit. This configuration is distinct from models designed for 100-240 VAC control power.
Integrated Motor Bypass
The internal bypass reduces thyristor conduction losses after motor acceleration, helping minimize 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, starting times from 2 to 30 seconds, adjustable initial torque and configurable soft stopping provide flexibility for different mechanical loads.
Electronic Motor Overload Protection
Integrated motor overload protection supports selectable Class 10, 15 and 20 trip characteristics. A normally open overload/fault auxiliary contact provides an interface for compatible monitoring and control circuits.
Compact IP2X Construction
The open-type controller measures 139.7 × 44.8 × 110 mm, weighs approximately 0.86 kg and has an IP2X protection rating. Documented steady-state heat dissipation is 17 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
- Mechanical equipment requiring controlled motor acceleration
- SMC-3 motor starter maintenance and replacement

Frequently Asked Questions
What is Allen-Bradley 150-C25NBR?
Allen-Bradley 150-C25NBR is a Bulletin 150-C SMC-3 solid-state soft starter rated at 25 A, designed for three-phase motor starting with a nominal 480 VAC main power supply and 24 V AC/DC control power.
What is the rated current of 150-C25NBR?
The controller has a 25 A current rating. Rockwell Automation specifies a line-connected motor current range of 9.2-25 A for supported 380/400/415/460 VAC installations.
What control voltage does 150-C25NBR require?
This model requires 24 V AC/DC control power. The documented control current during starting with the fan operating is 800 mA at 24 VDC or 660 mA at 24 VAC.
What is the difference between 150-C25NBR and 150-C25NBD?
The 150-C25NBR uses 24 V AC/DC control power, while the 150-C25NBD uses 100-240 VAC control power. These variants must not be interchanged without verifying the available control supply.
What motor horsepower range does 150-C25NBR support?
Manufacturer data specifies 7.5-15 HP for line-connected motors at 460 VAC and 7.5-20 HP for compatible inside-delta motor connections at 460 VAC. Actual selection depends on motor full-load current and starting duty.
Does 150-C25NBR support inside-delta motor connections?
Yes. The documented inside-delta motor current range is 14.3-43 A at the applicable 380/400/415/460 VAC operating conditions. Motor wiring and circuit protection must follow the manufacturer instructions.
Does 150-C25NBR include an internal bypass?
Yes. The controller includes an integrated bypass to reduce power losses during the applicable full-speed motor running condition.
What current limit settings are available?
The selectable current limits are 150%, 250%, 350% and 450% of motor full-load current. Starting time, initial torque and kick-start duration are also configurable.
Does 150-C25NBR include electronic motor overload protection?
Yes. The starter includes integrated electronic motor overload protection with selectable Class 10, 15 and 20 trip settings. The settings must match the connected motor and application requirements.
Can 150-C25NBR 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-C25NBR include a display or fault contact?
The controller 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-C25NBR?
Verify the manufacturer catalog number 150-C25NBR, 25 A controller rating, three-phase main supply voltage, 24 V AC/DC control supply, motor full-load current, line or inside-delta wiring, overload trip class, starting characteristics, fault contact wiring, IP2X protection and 139.7 × 44.8 × 110 mm installation dimensions.
