Product Overview
Downtime on a motor-driven process rarely waits for a purchase order. The Allen-Bradley 150-F108FBD-3-6P-HC3 Smart Motor Controller is a Bulletin 150 SMC-Flex soft starter built to keep three-phase motor circuits running in humid, dirty industrial environments. This unit combines contactor and overload protection functions into one device, so a single properly sized circuit breaker plus this controller can start and stop a motor on user-adjustable acceleration ramps.
With a 108 A current rating, 75 HP power rating, and line voltage range of 200 – 460 V AC at 50/60 Hz, this controller suits demanding pump, fan, and compressor duty. The NEMA Type 4/12 enclosure carries an IP 65 environmental rating, making it a practical choice where moisture and dust would sideline lesser equipment.

The 100 – 240 V AC control voltage range is a standout. It accepts control signals across that full band without modification, simplifying integration into existing control panels. The door-mounted HMI module includes a full numeric keypad, and the hands-off auto selector switch plus fused control circuit transformer add setup flexibility straight out of the box.
How It Compares
Buyers weighing soft starters against other motor control options should note the practical differences:
- Versus a standard contactor: A contactor provides on/off switching only. The 150-F108FBD-3-6P-HC3 adds adjustable acceleration ramps and integrated overload protection in one package.
- Versus a variable frequency drive: A VFD controls running speed continuously. This SMC-Flex unit focuses on controlled starting and stopping, which is often the simpler, lower-cost fit for fixed-speed motor loads.
- Versus a basic soft starter: The integrated HMI, selector switch, and fused transformer reduce the need for separate panel components and extra wiring.
Where It Fits
Water treatment plants, food processing lines, and oil and gas support facilities all deal with washdown, humidity, and airborne contamination. The IP 65 rating and Type 4/12 construction let this controller sit in those areas without an extra enclosure. The 75 HP rating covers many mid-size pump and fan motors found in these settings, and the three-phase design matches standard industrial motor circuits.
Selection Checklist
Before ordering, confirm your motor’s full-load amps stay within the 108 A rating, your supply voltage falls inside the 200 – 460 V AC line range, and your control circuit matches the 100 – 240 V AC band. Also verify the physical mounting arrangement suits a door-mounted HMI. Oil AutoTech offers hands-on technical selection help to match this controller to your application.
Please verify current lifecycle status and availability with Oil AutoTech before ordering.
Frequently Asked Questions
What motor size does the 150-F108FBD-3-6P-HC3 support?
It is rated for 108 A and 75 HP on three-phase loads with line voltage from 200 to 460 V AC at 50/60 Hz.
Does this controller need a separate overload relay?
No. The Bulletin 150 SMC-Flex design combines contactor and overload protection functions into one device, though a properly sized circuit breaker is still required.
What control voltage can I use?
The control voltage range is 100 – 240 V AC, so it accepts signals across that band without additional modification.
Can it handle washdown or humid areas?
Yes. The NEMA Type 4/12 enclosure with IP 65 rating is designed for humid and dirty worksites.
Is the HMI included?
Yes. This configuration includes a door-mounted human-machine interface module with a full numeric keypad, plus a hands-off auto selector switch and fused control circuit transformer.
