Overview
The Allen-Bradley 1492-CB2G100 is a 2-pole molded case circuit breaker engineered for reliable overcurrent protection in industrial and commercial electrical systems. With a 10A current rating and multi-voltage capability (240/277/480V AC), this breaker delivers dependable protection for a wide range of equipment and machinery. The compact DIN rail mounting design integrates seamlessly into control panels and distribution systems.
Key Features
- 2-pole configuration with simultaneous handle operation for coordinated protection
- Thermal-magnetic trip mechanism combining both sensing systems
- Multi-voltage rating: 240/277/480V AC compatible
- DIN rail mounting for quick, space-efficient panel installation
- Molded case construction for durability and consistent performance
- Screw termination accepting #16–4 AWG copper wire
Technical Specifications
The 1492 frame type delivers industry-standard protection characteristics. The thermal trip element activates on sustained overload conditions, while the magnetic mechanism responds instantly to short circuits. Both poles are mechanically linked to ensure simultaneous disconnection when a fault is detected.
Typical Applications
- Industrial motor control and machinery protection
- HVAC and equipment branch circuits
- Commercial panel installations requiring 480V three-phase distribution
- Supplementary overcurrent protection in control enclosures
- OEM equipment integration and retrofit applications
Compatibility & Replacements
The 1492-CB2G100 is part of the Allen-Bradley 1492 molded case circuit breaker family, which supports a range of accessories including lockout attachments and auxiliary contact modules. When upgrading or replacing existing 1492-series breakers, verify voltage and amperage ratings match your system requirements. As a Rockwell Automation product, this breaker integrates with standard industrial control panel designs and is compatible with standard DIN rail busbar systems. Consult datasheets for compatible auxiliary modules and mounting options.
