ABB 1SDA123605R1 Moulded Case CB - 4P DC, IEC 60947-2

Feature → Business Impact → Application: 4P DC Moulded-Case Design delivers robust protection across complete DC power paths, reducing fault propagation and enabling safer isolation in automation panels and energy systems. This architecture directly improves uptime and operator safety in factory floors and data centers. Feature → 320 A Rated Current and 4 Poles → Ensures reliable load protection at high continuous currents, minimizing nuisance trips in DC feeders and enabling scalable automation architectures. Application: Suitable for centralized DC distribution in manufacturing lines and control cabinets. Feature → 750 V DC Rated Operational Voltage and 1000 V Insulation Voltage → Expands applicability to higher-voltage DC networks, enabling safe integration with energy storage or fast-charging interfaces while maintaining strict isolation. Application: Data centers and process industries with aggressive DC bus requirements. Feature → 36 kA Ics / 36 kA Icu (depending on configuration) → High short-circuit withstand capacity reduces the risk of cascading failures during faults. Application: Protective coordination in heavy DC feeders and critical automation loops. Feature → TM/TMA Release System and Fixed Terminal Connection → Delivers fast, reliable tripping and straightforward installation with stable, vibration-resistant mounting. Application: Panel assemblies and fixed-bracket installations in harsh environments. Feature → Mechanical Durability of 20,000 cycles at 120 cycles/hour → Lower maintenance intervals and longer service life, cutting replacement costs and downtime. Application: Refill-cycle heavy automation cabinets with minimal intervention. Feature → Power Loss of 16.9 W per pole → Predictable thermal performance, enabling accurate heat dissipation planning in control panels. Application: Compact, dense panel designs where thermal margins are tight. Feature → ABB EcoSolutions and End-of-Life/Environmental Declarations → Supports sustainability goals, responsible disposal, and resource loop closing in line with EN45555 and EPD programs. Application: Green procurement programs and corporate responsibility reporting in manufacturing.
