Key Features

1. Advanced Solid-State Trip Technology
   • Digital RMS sensing accurately measures both sinusoidal and non-sinusoidal currents, minimizing nuisance tripping in harmonic-rich environments.
   • LSI protection (Long-Time, Short-Time, Instantaneous) offers adjustable settings for precise coordination with downstream devices.
   • Interchangeable trip units allow for easy rating changes without replacing the entire breaker.
2. High Interrupting Capacity & Current Limiting
   • Withstand high fault currents up to 100 kA (at 240 VAC) to protect equipment and wiring from severe damage.
   • Current-limiting design quickly extinguishes arcs, reducing fault energy and minimizing damage to the electrical system.
3. Robust & Flexible Design
   • Compact E-frame size saves panel space while maintaining high performance.
   • Bolt-on mounting enables easy installation and removal in standard switchboards and panelboards.
   • Suitable for reverse feed applications, offering versatility in system design.
4. Comprehensive Safety & Compliance
   • UL and CSA certified for industrial safety and electromagnetic compatibility (EMC).
   • HACR-rated for use in heating, ventilation, air conditioning, and refrigeration (HVACR) systems.
   • Front-accessible rating plugs and trip adjustments simplify on-site configuration and maintenance.
5. Durability & Reliability
   • Rugged molded case construction withstands mechanical stress, vibration, and temperature fluctuations.
   • High-quality internal components ensure long-term reliability and reduced maintenance costs.
