Overview
The Allen-Bradley 109-C09AATB24-1-7 is a compact IEC enclosed motor starter designed for industrial motor control applications. Part of the proven 109-C series, this enclosure-based starter combines motor protection, contactor, and overload relay functions in a single integrated unit. The Series A design delivers reliable on-demand motor starting and stopping with built-in safety features for continuous operation in manufacturing, material handling, and process control environments.
Key Features
- IEC-compliant enclosed motor starter with integrated contactor and thermal overload protection
- Series A enclosure construction for NEMA Type 1, 4, 4X, 12, or 12K ratings (depends on cabinet configuration)
- Compact form factor enabling space-efficient panel integration
- Manual and automatic reset capabilities for overload conditions
- Support for 22.5 mm indication and command devices (pilot lights, push buttons, selector switches)
- Direct replacement for legacy 109-C series units in existing installations
Technical Specifications
The 109-C09AATB24-1-7 supports flexible configuration for different motor duty cycles and electrical requirements. Typical applications involve motors ranging from fractional to several horsepower, with coil voltage options for standard industrial supply voltages.
Typical Applications
- Motor control starter stations in manufacturing lines and assembly systems
- Material handling equipment (conveyors, hoists, pumps)
- Process automation and batch control systems
- Replacement for obsolete or damaged starter enclosures in legacy plants
- Integration into custom control panels with modular 22.5 mm devices
Compatibility & Replacements
Compatible With
- IEC-standard three-phase motor loads (squirrel-cage induction motors)
- Standard industrial control systems using 110/120 VAC, 220/240 VAC, or 380/400 VAC coil voltages
- 22.5 mm indication and command devices (push buttons, pilot lights, selector switches)
