1336F-B125-AA-EN Allen‑Bradley 1336 FORCE AC Variable Frequency Drive

Product Description

1336F-B125-AA-EN is a 125HP (90kW) three-phase AC variable frequency drive from Allen‑Bradley 1336 FORCE series, manufactured by Rockwell Automation. This microprocessor-controlled PWM inverter provides adjustable frequency and voltage output to regulate the speed of three-phase induction motors. The unit is equipped with built-in dynamic braking IGBT, NEMA Type 1 (IP21) enclosure, and English HIM human interface module. It supports constant torque operation with 150% overload capacity for heavy-duty industrial motor control.

Product Features & Functions

• 125HP / 90kW rated power, three-phase PWM output for induction motor speed regulation
• Integrated dynamic braking IGBT for fast motor deceleration (requires external brake resistor)
• 150% overload capability for heavy-duty and shock load working conditions
• NEMA Type 1 (IP21) enclosure for cabinet mounting in clean industrial environments
• English HIM local panel for parameter setup, status display and fault diagnosis
• Built-in comprehensive protection: overcurrent, overvoltage, undervoltage, overheat and ground fault protection
• SCANport communication interface for remote control and data exchange with PLC systems
• Non-volatile memory to save motor parameters and user configuration settings

Application Scenarios

• Heavy-duty motor speed control for conveyors, fans, pumps and compressors
• Metallurgy, mining, cement and paper mill production line main drive control
• Water treatment, chemical plant and power plant auxiliary motor variable speed control
• Legacy 1336 series drive replacement, system overhaul and spare parts maintenance
• Material handling, extruder and large machinery constant torque control projects

FAQ

Q: What does 1336F-B125-AA-EN stand for?
A: 1336F = FORCE series; B = built-in dynamic brake IGBT; 125 = 125HP rating; AA = NEMA Type1 enclosure; EN = English HIM & documentation.

Q: Is dynamic braking ready on this drive?
A: It has integrated braking IGBT, but an external brake resistor must be installed to realize dynamic braking function.

Q: Is this Allen‑Bradley drive still in production?
A: Rockwell has discontinued the entire 1336 series. Only new old stock, used and refurbished drives are available on the spare parts market.
