Key Features
100-240VAC Control Supply
The controller uses a 100-240 VAC control circuit and supports a nominal 480 VAC three-phase main power circuit. This configuration differs from the corresponding 24 V AC/DC control variant.
Integrated Motor Bypass
The internal bypass reduces thyristor conduction losses after motor acceleration, helping decrease heat generation and power losses during the normal running condition.
Adjustable Starting and Stopping
The SMC-3 provides selectable current limits from 150% to 450% of motor full-load current, starting times from 2 to 30 seconds, adjustable initial torque and configurable soft-stop operation.
Electronic Motor Overload Protection
Built-in electronic overload protection offers selectable Class 10, 15 and 20 trip characteristics. A normally open overload/fault contact provides a signal for compatible monitoring circuits.
Compact IP2X Controller
The open-type controller measures 139.7 × 44.8 × 110 mm and weighs 0.86 kg. Its documented steady-state heat dissipation is 15 W, supporting compact industrial motor control installations.
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 with 100-240VAC control circuits
- Industrial equipment requiring controlled motor acceleration
- SMC-3 motor starter maintenance and replacement

Frequently Asked Questions
What is Allen-Bradley 150-C19NBD?
Allen-Bradley 150-C19NBD is a Bulletin 150-C SMC-3 solid-state soft starter rated at 19 A, designed for compatible three-phase induction motors with a nominal 480 VAC main power circuit and 100-240 VAC control power.
What is the current rating of 150-C19NBD?
The controller has a 19 A rated current. The manufacturer specifies a line-connected motor current range of 6.3-19 A for supported 380/400/415/460 VAC applications.
What control voltage does 150-C19NBD require?
This model requires a 100-240 VAC control supply. Documented control 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-C19NBD and 150-C19NBR?
The 150-C19NBD uses a 100-240 VAC control supply, while the 150-C19NBR uses 24 V AC/DC control power. The two models must not be interchanged without confirming control circuit compatibility.
What motor horsepower range does 150-C19NBD support?
The documented motor power ranges at 460 VAC are 5-10 HP for line-connected motors and 5-15 HP for compatible inside-delta installations. The motor nameplate current and starting duty must also be considered.
Does 150-C19NBD support inside-delta motor connections?
Yes. The manufacturer documents an inside-delta motor current range of 10.9-32.8 A for supported 380/400/415/460 VAC installations. Proper wiring and protective device selection are required.
Does 150-C19NBD include an internal bypass?
Yes. An internal bypass reduces 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. The controller also provides configurable starting time, initial torque and kick-start settings.
Does 150-C19NBD provide motor overload protection?
Yes. Integrated electronic motor overload protection supports Class 10, 15 and 20 trip settings. The appropriate setting must be selected for the connected motor and its operating duty.
Can 150-C19NBD perform soft stopping?
Yes. Soft stopping can be disabled or configured for 100%, 200% or 300% of the selected starting time when properly wired and configured.
Does 150-C19NBD 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, with operational ratings of 0.6 A at 120 VAC or 0.3 A at 240 VAC.
What should be checked before ordering 150-C19NBD?
Verify the exact catalog number 150-C19NBD, 19 A current rating, three-phase main power supply, 100-240 VAC control voltage, motor full-load current, line or inside-delta connection, overload class, starting settings, short-circuit protective devices, IP2X enclosure requirements and 139.7 × 44.8 × 110 mm mounting dimensions.
