Feature → Business Impact → ApplicationThe 4-pole DC design (630 A, 750 V DC) delivers robust protection for high-current DC buses, reducing fault propagation and downtime. This enables reliable motor drives and DC links in automated plants, data centers, and energy storage systems. The result is improved system availability and lower maintenance costs.High short-circuit withstand and breaking capacities (Ics and Icu) across voltage levels ensure fast fault clearance without compromising downstream equipment. This is critical for renewable energy interfaces, grid-triendly DC networks, and industrial drives where resilience matters.Rated operational voltage of 750 V DC with Ui up to 1000 V provides a broad margin for future expansion and higher-energy applications, simplifying panel design and procurement while preserving safety margins for installation engineers.Mechanical durability at 20000 cycles supports frequent switching in automation lines, reducing replacement cycles and maintenance interventions in manufacturing cells and packaging lines.Power loss of 34.4 W per pole at rated conditions supports thermally predictable operation, aiding cooling design and energy efficiency plans in compact control panels and high-density switchgear assemblies.ABB EcoSolutions and environmental declarations (EPD, 60% recyclability per EN45555) allow teams to meet sustainability targets and regulatory requirements, improving total cost of ownership and corporate responsibility metrics.Fixed circuit-breaker terminals simplify installation and service access, enabling quicker panel mounting, cleaner wiring, and reduced commissioning time in control cabinets and MCC rooms.Compliance with IEC 60947-2 and CE declarations provides procurement confidence and smoother integration into industrial control panels, avoiding last-minute design changes during audits.
