ABB 1SDA050473R1 Moulded Case Circuit Breaker - X

Three-pole operation with a rated current of 630 A and fixed installation reduces wiring complexity and ensures reliable protection in Isomax S6 panels. In practical terms, this means faster assembly, less miswiring, and lower commissioning risk on critical lines. Engineers can rely on front-terminal access for testing and maintenance, which shortens downtime during inspections and replacements in manufacturing lines and conveyors. PR212/P-LSI solid-state release provides precise tripping characteristics and fast response under short-circuit conditions. The business impact is safer energization sequences and reduced risk of nuisance tripping in load-heavy machines, with clear diagnostic signals for maintenance teams. This release type supports seamless integration with ABB protection schemes across Isomax S6 installations. Rated operational voltage of 690 V AC offers a generous insulation margin for global industrial environments. This compatibility reduces the need for multiple parts variants, cutting total cost of ownership and simplifying procurement for multi-site deployments. In practice, you gain a unified protection platform for motors, drives, and feeders within Isomax S6 architectures. Short-Circuit Performance Level X indicates strong fault current handling. It translates to higher system reliability during faults and improved coordination with upstream protections. Engineers can design safer, more resilient panels for conveyors, energy-intensive equipment, and critical process lines. Electrical durability of 7000 cycles demonstrates long service life under frequent switching and fault events. This translates to lower maintenance intervals and reduced spare parts use, boosting uptime in high-demand environments like packaging, metals processing, or automotive assembly lines. With RoHS and CE declarations, the product also supports regulatory compliance. Dimensions and weight — 305 mm width, 285 mm height, 0.1035 m depth, and ~15 kg — enable predictable fit in standard MCCB enclosures. Front-terminal configuration accelerates installation and simplifies retrofits in existing switchgear, while the fixed version ensures consistent performance across cabinets. Overall, these specs support streamlined procurement and maintenance planning for panel builders.
