Overview of Allen Bradley 1492-SPM1C250

The Allen Bradley 1492-SPM1C250 is a single-pole miniature circuit breaker designed to provide supplementary protection in industrial automation panels. Manufactured under Rockwell Automation’s Bulletin 1492-SPM line, this breaker features a 25A current rating and a trip Curve C characteristic, making it suitable for reliable overcurrent protection in equipment where UL 1077 supplementary protection is accepted. The compact design, thermoplastic housing, and DIN rail mounting enable straightforward integration into control cabinets, reducing downtime and simplifying system layouts. The 1492-SPM1C250 operates efficiently at a rated voltage up to 277V AC per UL and 230V AC per IEC with a high interrupting capacity, making it a dependable component in demanding environments such as process control, power distribution, and equipment manufacturing.

Key Features of Allen Bradley 1492-SPM1C250

  • Rated 25A with 1-pole configuration for load-specific applications
  • Trip Curve C for moderate inrush current tolerance

Applications / Use Case

The Allen Bradley 1492-SPM1C250 is engineered for supplementary protection in industrial control systems, automation panels, machine tools, and OEM equipment. It is widely adopted where additional protection is required for individual loads or devices—beyond what is provided by branch circuit protection. Common scenarios include protecting sensitive PLC input/output points, control transformers, pilot devices, and small motors from overcurrent scenarios without tripping main circuit protection. Its fast installation is ideal for system integrators and maintenance teams working with distributed power architectures or retrofitting control systems. The device’s global certifications also support export-ready panel designs for worldwide deployment.
