Product Introduction

The Allen-Bradley 1336F-BRF50-AA-EN-HAS2 is a 5 HP 1336 PLUS II adjustable-frequency AC drive intended for variable-speed control of industrial AC motors. Its 380–480 VAC input class and 3.7 kW rating place it in the common low-power motor-drive range used for pumps, fans, conveyors, machine auxiliaries, and other variable-speed loads.

The HAS2 designation is important when sourcing a replacement because it identifies the drive’s Programmer/Controller human-interface configuration with a digital potentiometer. A replacement that matches only the 1336 PLUS II family but has a different HIM or option configuration should not automatically be treated as a direct equivalent.

Application Scenarios & Field Pitfalls — Engineer’s Perspective

Engineering Pain Point

With an older 1336 PLUS II installation, a drive failure is not always a reason to change the entire control architecture. The more immediate challenge is finding a replacement with the same power class, voltage class, HIM configuration, option boards, firmware/series characteristics, and motor application parameters.

Typical Applications

  • Conveyor and material-handling motor control
  • Pump and fan speed regulation
  • Machine-tool and process auxiliary drives
  • Legacy Allen-Bradley motor-control panels

Technical Pitfalls to Avoid

  1. Match the complete catalog number.
    The BRF50 portion identifies the 5 HP / 3.7 kW class, while HAS2 identifies the specific HIM configuration. Do not substitute a visually similar 1336 PLUS II without checking the complete catalog string.
  2. Check the actual input supply.
    This catalog number is associated with the 380–480 VAC class and 513–620 VDC input range. Confirm the plant supply before installation rather than relying on the motor nameplate alone.
  3. Check option modules separately.
    Related 1336F catalog numbers can carry additional option designations for pulse I/O, analog I/O, and control-voltage configurations. A base catalog-number match does not establish that an extended option configuration is identical.

Procurement Check

Before approving a replacement for , verify:

  • Exact catalog number:
  • Series/revision
  • 380–480 VAC input class
  • 5 HP / 3.7 kW rating
  • HIM configuration
  • Installed option boards
  • Motor nameplate voltage and current
  • Motor control mode and application parameters
  • Existing drive parameter backup
  • Control wiring and I/O configuration
  • Enclosure and cooling conditions
  • Physical terminal and connector condition

Recommended procurement description:

Alle3 1336 PLUS II Adjustable Frequency AC Drive, 5 HP / 3.7 kW, 380–480 VAC, English Programmer/Controller HIM with Digital Potentiometer, IP20/NEMA 1.

For a field replacement, the key point is that 336F- is a complete legacy AC drive catalog configuration, not merely a control board. Match the full catalog number and option configuration before treating another 1336F unit as a substitute.
