Four-pole LG-frame design enables high current handling (630 A) in a compact footprint, reducing panel depth and wiring complexity. This improves space utilization and shortens installation time, delivering tangible capital efficiency for new builds and retrofits in machine frames. The Digitrip 310 RMS electronic trip provides precise, fast protection with adjustable protection for the neutral pole. This improves selectivity and minimizes unplanned downtime during motor startup and fault events, ideal for conveyors, mixers, and packaging lines. Interrupt ratings of 85 kAIC at 240 VAC, 50 kAIC at 415/480 VAC, and 25 kAIC at 600 VAC ensure robust fault-current handling across diverse power sources, reducing the risk of collateral damage and unplanned outages. HACR-rated operation supports safe motor control in compliance with electrical codes, while UL Listed, CSA Certified, IEC Rated, and CE Marked certifications back global deployment. Terminals are designed for clear line/load connections, and metric mounting hardware simplifies panel integration. The protected neutral pole (0–100% adjustable) enables flexible protection schemes for mixed loads, improving reliability and facilitating planning for future expansions in automated facilities. Overall, the solution offers easy retrofit potential, compatibility with Eaton accessories, and a clear path to lower maintenance costs over time.
