Allen-Bradley 1336-B003-E0D Electronic Electrical Component
Allen-Bradley 1336-B003-E0D
1. Overview
Product Positioning: The Allen‑Bradley 1336‑B003‑E0D is a specific configuration within the 1336 Series, belonging to the Series A (Constant Torque) family of adjustable‑frequency drives.
Key Function: This high‑performance three‑phase variable‑frequency drive (VFD) is designed to control standard three‑phase induction motors. It uses microprocessor‑based control to provide variable motor speed and consistent torque output.
Technical Architecture: The drive employs microprocessor‑controlled inverter technology with an integrated three‑phase PWM (Pulse Width Modulation) circuit. This allows precise control over motor starting, acceleration, deceleration, and stopping.

2. Parameters
Power Rating: The B003 designation typically corresponds to a 3 HP (approximately 2.2 kW) power level.
Voltage Range: Compatible with 380V–415V industrial power systems. (Compatibility with 460V may vary and should be confirmed based on specific unit specifications.)
Current Rating: Typical rated current is 6–7A, matching the 3 HP power class.
Torque Characteristics: As part of the Series A (Constant Torque) line, this model is ideal for applications requiring stable torque across varying speeds, such as conveyors and compressors.
Enclosure Rating: The “E” enclosure code generally indicates NEMA 1 (IP20), suitable for indoor use in non‑hazardous environments.

3. Product Features
Constant Torque Performance: Series A drives maintain consistent torque output across a wide speed range, a critical advantage for applications where load stability is essential.
Programmability: The drive supports digital programming via the front‑panel keypad or serial communication ports such as 1553, DH+, DeviceNet, ControlNet, and EtherNet/IP.
Comprehensive Diagnostics: A detailed fault code system provides clear status information via the front panel or communication links, enabling quick troubleshooting.
Surge Protection: Equipped with MOV (Metal Oxide Varistor) technology to protect against line‑to‑line and line‑to‑ground voltage surges.
