The Power Defense SB low-voltage insulated case circuit breaker (ICCB) with Power Xpert Release (PXR) technology deliver accurate and intelligent circuit protection for UL891 switchboard applications.

The digital enhancements of the PXR electronic trip units combined with the proven reliability of Eaton’s air circuit breakers (ACB) provide customers the ability to improve system health, accurately and efficiently diagnose system issues, and field test quickly for increased uptime.

The PXR trip units provide an enhanced and easy-to-use software interface, which displays a summary for critical performance metrics, such as current and energy usage, battery life, and Zone SelectiveInterlocking (ZSI) status. Additionally, a scroll-through menu provides access to more detailed metrics, password protected settings, and access to the testing functionality.

• Maintenance at a safe distance
  Industry-exclusive motorized remote racking (MR2) feature allows you to perform maintenance through our intuitive software at a safe distance.
• Eliminate the need for separate breakers
  Embedded communications and revenue-grade energy metering accuracy help to reduce cost by eliminating the need for separate meters. Easily connect and push data through our Power Distribution Monitoring and Control via direct Modbus RTU or Modbus TCP communications adapter module (CAM).
• Secondary injection testing
  Cost effectively perform secondary injection testing with our intuitive Power Xpert Protection Manager (PXPM) software. 

• Predictive maintenance
  Breaker health and advanced algorithms help avoid costly downtime by enabling predictive maintenance on your power distribution system prior to component failure.
• Reduce potential incident arc flash energy levels
  Arc Flash Reduction Maintenance System reduces potential incident arc flash energy levels by faster clearing times at lower instantaneous pickup levels, reducing your PPE requirements and improving personnel safety and productivity. 
• Avoid downtime - pre-trip indicators
  Multiple programmable high load and ground fault alarms help avoid costly downtime by providing pre-trip indications.
