The 1336-WB035 is a dynamic braking chopper specifically designed for industrial AC frequency converters. It controls the DC bus voltage by switching on a transistor, and in conjunction with an external braking resistor, converts the regenerative energy generated during motor deceleration into heat energy for dissipation, thereby providing up to 100% of the rated braking torque.
Rugged IGBT Chopper Switching
Dual-Fuse & Automation Fault Loop
High-Capacity Overvoltage Prevention
This open-chassis module delivers rugged performance under demanding braking profiles, utilizing a high-efficiency IGBT (Insulated Gate Bipolar Transistor) switching mechanism rated for 35A DC (RMS) continuous current. Built to withstand rigorous industrial environments, it features integrated dual protective fuses (F1 & F2) to isolate hardware faults instantly during external resistor short-circuits, paired with a TTL-compatible Normally Closed (N.C.) contact for direct PLC alarm integration. As a highly sought-after factory replacement part, it offers an economical solution for maintenance teams looking to extend the lifecycle of their existing 1336 drive networks—such as cranes, hoists, and centrifuges—without requiring full-scale control system overhauls.

Steel Mills
Absorbs high-current reverse spikes during millisecond-level directional changes in high-speed reversing rolling lines.
Paper Mills
Controls quick speed corrections and emergency braking on high-speed calendar rolls and winders to maintain web tension.
Automotive
Acts as an electrical damper to protect drive capacitors from repetitive power feedback loops caused by heavy mechanical stamping presses.
Chemical Plants
Controls the rapid electrical braking of high-viscosity compound mixing blades to avoid runaway batch curing inside reactors.
Glass Plants
Controls deceleration rates on gantry cutting tables to prevent tool collisions and maintain high cutting precision.
Cranes & Hoists
Dissipates gravitational back-EMF when heavy gantry or overhead cranes lower large industrial loads, preventing overvoltage drive trips.
Before installing or maintaining the 1336-WB035 chopper module, always disconnect the input power and wait at least 5 minutes to verify that the residual high voltage on the drive’s DC bus capacitors has fully discharged before touching any wiring. The resistance value of the connected external braking resistor must strictly never fall below 9 Ohms, as lower resistance will cause excessive current and burn out the module. Due to its open-chassis structure, adequate clearance space must be maintained at the top and bottom during installation to ensure proper ventilation for IGBT cooling. Additionally, always wire the module's Normally Closed (N.C.) fault contact into the PLC safety interlock loop to trigger immediate shutdown protection if an internal fuse blows or overheating occurs.
The 1336-WB035 is an industrial-grade dynamic brake chopper module from the Allen-Bradley brand under Rockwell Automation, used specifically as an electrical expansion option for the 1336 AC drive systems.
What is the core purpose of the 1336-WB035 module?
When a heavy-duty motor decelerates rapidly, it generates regenerative energy that spikes the drive's DC bus voltage. The 1336-WB035 automatically turns on to redirect this excess energy into an external brake resistor to be dissipated as heat, preventing overvoltage faults on the drive.
How should the 1336-WB035 be used in an application?
It cannot operate independently. It must be wired directly to the DC+ and DC- bus terminals of a 1336 AC drive, and a properly rated power braking resistor must be connected to its output terminals.
Which Allen-Bradley drive systems are compatible with the 1336-WB035?
It is fully compatible with the Bulletin 1336 drive family, including the well-known 1336 PLUS, 1336 PLUS II, 1336 FORCE, and 1336 IMPACT AC drive systems.
What is the rated current specification for the 1336-WB035?
Its rated continuous operating current is 35A DC (RMS value), built to handle heavy-duty industrial drive braking requirements.
