• Catalog number: 150-F85NBRB
• Controller family: Bulletin 150
• Controller type: Smart Motor Controller
• Control method: Solid-state
• Enclosure configuration: Open enclosure
• Application designation: Pump control

Electrical and Mechanical Specifications

Solid-State Motor Control Characteristics

The 150-F85NBRB uses solid-state switching for three-phase motor control. The stated 85 A current rating and 60 hp power rating define the supplied motor-control capacity.

The input line specification is listed as 200-480 VAC, 3-phase, 50/60 Hz in the technical data. The product information separately states 200-460 VAC. Application selection should therefore be based on the exact nameplate and applicable Allen-Bradley documentation.

The control circuit operates from 24 VAC/DC. Control wiring should remain electrically separated from the incoming three-phase power conductors and motor output conductors.

Pump Control Interface

The supplied product information identifies pump control as an application function. Installation should account for motor starting current, connected motor rating, line voltage, phase configuration, and the required control circuit.

No specific pump control algorithm, overload trip curve, acceleration profile, or bypass configuration is provided in the supplied data. These parameters should not be inferred from the catalog number alone.

Ordering Information

• Additional bypass components, overload devices, contactors, mounting hardware, or control accessories are not specified in the supplied product data.

Field Installation Guidelines

Power Circuit

• Verify the incoming supply is three-phase and within the applicable controller voltage range.
• Confirm the motor current does not exceed the controller rating of 85 A.
• Match the motor power rating with the specified 60 hp controller application rating.
• Use appropriately rated conductors and protective devices for the connected motor circuit.

Control Circuit

• Provide the specified 24 VAC/DC control voltage.
• Separate low-voltage control wiring from high-voltage power wiring where practical.
• Confirm control polarity when using a DC control supply.
• Do not connect control terminals to voltages outside their specified control rating.

Thermal and Mechanical Installation

• Mount the open-enclosure controller inside a suitable electrical enclosure.
• Provide ventilation appropriate for the installed equipment and enclosure arrangement.
• Maintain conductor routing that prevents unnecessary coupling between control and power circuits.
• Verify all terminal connections before energizing the controller.

Frequently Asked Questions

• What is the current rating of the 150-F85NBRB?

  The specified controller current rating is 85 A. The connected motor load should be selected so that its operating current remains within the applicable controller rating.

• What motor power is specified?

  The product data identifies a 60 hp power rating. Actual motor selection must also consider line voltage, motor current, frequency, and installation conditions.

• What input voltage does the controller accept?

  The technical specification lists 200-480 VAC, 3-phase, 50/60 Hz. The product description separately lists 200-460 VAC, so the exact nameplate range should be verified.

• What control voltage is required?

  The specified control voltage is 24 VAC/DC. Control wiring must be connected according to the applicable terminal arrangement and supply polarity requirements.

• Is the 150-F85NBRB a solid-state controller?

  Yes. The supplied product information identifies it as a solid-state Smart Motor Controller under the Bulletin 150 family.

• Is the controller suitable for three-phase motors?

  Yes. The supplied specifications identify a 3-phase input configuration with a 200-480 VAC line-voltage range at 50/60 Hz.

• Is the controller supplied in an enclosed housing?

  No. The supplied product information identifies the configuration as an open enclosure. It therefore requires suitable installation protection.

• What installation information is available for temperature limits?

  No operating-temperature value is provided in the supplied data. The controller should therefore be installed according to the applicable manufacturer environmental specifications.
