ABB 1SDA054336R1 Moulded Case Circuit Breaker - 8 kV

Front-terminal, fixed 3P design accelerates wiring and reduces field errors, enabling faster commissioning and cleaner panel layouts. Business impact includes reduced installation time, lower labor costs, and easier future upgrades, making it an ideal fit for distribution boards in manufacturing lines and power centers. The 320 A rating at 690 V AC paired with 8 kV impulse withstand delivers reliable protection against high-energy faults, improving system uptime and safeguarding critical loads such as motors and transformers. In practice, contractors gain predictable protection coordination with PR222DS/P-LSI, a solid-state release that enhances selective tripping and fast response under fault conditions. This aligns with long-term maintenance planning and reduces forced outages in demanding processes, while supporting compliant documentation for audits. The 3P configuration supports common industrial topologies and simplifies replacement in legacy Tmax T5 installations, with front-terminal access that eases retrofits and minimizes wiring complexity. Durability figures—7000 electrical cycles and 20000 mechanical cycles—translate into extended service life in frequent-switching environments, lowering total cost of ownership. When integrating RoHS, REACH, and CE declarations, the solution supports sustainability and regulatory compliance across global supply chains. Dimensions and weight (140 mm x 205 mm x 103.5 mm / 5.1 kg) enable straightforward packaging, transport, and mounting within standard enclosures, reducing support calls during installation. The combination of solid performance, clear data, and familiar Tmax T5 compatibility helps procurement consolidate spares and streamline lifecycle management.
