Overview of Allen Bradley 1492-SPM1C320

The Allen Bradley 1492-SPM1C320 is a single pole miniature circuit breaker engineered to provide supplementary protection for control circuits, lighting, pilot devices, coils, and small transformers. As part of Rockwell Automation’s 1492-SPM family, this model is rated for 32 amps and features a Type C trip curve, making it suitable for medium inrush current applications. The breaker is designed for use where branch protection, as defined by UL489, is not required, offering added safety and component longevity. It is UL1077 and IEC 60947-2 compliant, meeting global standards for performance and reliability. This device is often installed on DIN rails and supports accessory options for flexible panel configurations. With visible ON/OFF status indicators and compact dimensions, the 1492-SPM1C320 supports efficient diagnostics and space utilization within control panels.

Applications / Use Case

Allen Bradley 1492-SPM1C320 circuit breakers are commonly used to protect auxiliary circuits in industrial automation panels. Their medium inrush tolerance (Type C curve) is ideal for loads that include control transformers, lighting banks, solenoids, pilot devices, and relay coils. Engineers specify the 1492-SPM1C320 where overcurrent protection is needed without requiring branch-level protection—such as in machine control cabinets, OEM panels, process control stations, and building automation enclosures. The slim design allows for high-density installations, while the compatibility with bus bars and accessories reduces wiring errors and simplifies maintenance. Users appreciate its international certifications, making it a preferred solution in global equipment builds.
