Configured for solid-state reduced voltage starting and torque control in 3-phase AC motor circuits, the Allen-Bradley 150-F85NBR (150-F85NBR Smart Motor Controller) provides direct physical/electrical execution.

Catalog Nomenclature & Configuration

The Allen-Bradley 150-F85NBR belongs to the Bulletin 150 solid-state motor controller product line. Catalog code 150-F85NBR designates an 85 A current-rated soft starter with a 60 hp capacity at 460 V AC. The module utilizes an open enclosure construction, handles 200 to 480 V AC 3-phase line power, and requires a 24 V AC/DC control circuit supply.

Physical & Electrical Parameters

Deterministic Industrial Network Interfacing

When configured with option cards for system architectures, the unit integrates with EtherNet/IP deterministic networks for real-time telemetry transfer and command processing. Internal digital logic circuits govern phase-angle SCR firing, optimizing I/O density scaling within panel layouts. The main control board features firmware flash compatibility, enabling field upgrades without replacing the power structure.

Wiring & Mounting Instructions

• De-energize and lock out all 3-phase power line connections and auxiliary 24 V AC/DC control feeds before handling hardware.
• Mount the open enclosure frame vertically on a rigid panel surface to ensure unimpeded natural thermal convection across the heatsink fins.
• Connect line terminals (L1, L2, L3) and load terminals (T1, T2, T3) using copper conductors torqued to factory rating standards.
• Terminate low-voltage 24 V AC/DC control lines separately from high-voltage AC power lines to avoid inductive noise coupling.
• Bond the main protective ground lug directly to the central electrical enclosure earth bus bar using a low-impedance conductor.

Technical Reference FAQ

• What is the continuous current rating of the 150-F85NBR?

  The 150-F85NBR is engineered for a maximum continuous operating current of 85 A across 3-phase induction motor loads.

• What control supply voltage is needed for logic operation?

  The internal control board operates on a nominal supply voltage of 24 V AC/DC connected to dedicated control terminals.

• What is the motor power capacity at 460 V AC line input?

  When connected to a 460 V AC 3-phase line, the controller manages standard induction motors rated up to 60 hp.

• Does the assembly include a NEMA protective enclosure?

  No, the unit features an open enclosure specification and must be housed within a suitable industrial control panel.

• What supply line voltage range does this soft starter accept?

  The main power structure accommodates 3-phase line voltages ranging from 200 to 480 V AC at 50/60 Hz.

• How are firmware updates performed on the control module?

  Firmware flash compatibility allows field engineers to update logic routines via serial or network communication adapters.

• What thermal clearance is required during panel installation?

  Maintain a minimum vertical clearance above and below the heatsink to facilitate adequate air convection across the cooling assembly.

• Can the control power leads be routed alongside 3-phase power cables?

  No, 24 V AC/DC control wiring must be segregated from high-voltage line and motor leads in separate conduits to block EMI.
