Allen Bradley 1336-WB110 Dynamic Brake Chopper Module

The Allen‑Bradley 1336-WB110 is a dynamic brake chopper module designed exclusively for Rockwell 1336 series adjustable frequency AC drives, including 1336VT, 1336PLUS, 1336PLUSII, 1336FORCE and 1336IMPACT drives. It dissipates regenerative energy from decelerating motors by switching the built‑in 2.5 ohm brake resistor onto the DC bus, which greatly boosts braking torque from 10% up to 100% for fast stop and heavy inertial load applications.

This chopper module operates on 380–480V AC input, with continuous DC bus voltage rating up to 750V DC and 110A continuous rating. It integrates an IGBT chopper transistor for precise DC bus voltage regulation during regeneration, plus an SCR overvoltage crowbar circuit and Ferraz Shawmut fuse for reliable overvoltage and short‑circuit protection. It supports parallel connection of multiple chopper units for higher braking power requirements on large‑horsepower drives. Brake fault TTL output enables drive system alarm interlock for maintenance monitoring.

Equipped with status indicators, the 1336-WB110 helps technicians quickly identify resistor faults, fuse failures and overvoltage conditions. Rugged industrial construction is engineered for continuous operation in control cabinets with vibration, electrical noise and fluctuating ambient temperature. It is widely used on conveyors, cranes, hoists, centrifuges and other machinery that requires rapid deceleration or emergency stop.

Rockwell Automation has discontinued the 1336-WB110, so it is primarily supplied as surplus original spare parts for existing 1336 drive fleets. It is highly sought after by maintenance teams, system integrators and plant procurement engineers for legacy drive repair, brake function upgrade and machine retrofit projects across mining, material handling, metal processing, cement and water treatment industries.

We supply new original Allen‑Bradley 1336-WB110 from stock. Every unit is inspected before shipment to verify label integrity, resistor continuity and fuse condition. Standard warranty is available, and we support worldwide express delivery via DHL, FedEx or UPS. If you need to confirm compatibility with your existing 1336 drive model and horsepower rating, send us your drive catalog number for technical verification.
