ABB 1SDA065487R1 Moulded Case Circuit Breaker - Tmax

Front-terminal design significantly simplifies field wiring and reduces panel depth, enabling faster commissioning and minimizing the risk of miswired connections under pressure. This MCCB model uses a fixed two-pole arrangement with clearly labeled front terminals that support clean, reliable terminations even in densely populated control cabinets. For panel builders and integrators, that translates into measurable installation time savings, fewer field rework incidents, and improved overall traceability of protective devices. Thermomagnetic release TMF provides precise protection against overloads and short circuits, preventing nuisance trips while maintaining selective coordination with upstream protection devices. The 80-800 A current-range covers common motor starters, drives, and distribution circuits, and the fixed setting reduces field adjustment errors that commonly occur during commissioning. In practice, you gain predictable protection performance, easier compliance with UL 489/CSA C22.2 standards, and a safer workplace. Compact footprint fits tighter panels without sacrificing visibility of status indicators or spacing for wiring and cooling. With product net dimensions of 105 mm width, 170 mm height, and 103.5 mm depth, and a weight of 1.6 kg, it remains manageable for installation on standard DIN rails or fixed chassis within compact enclosures. This balance of size, weight, and robustness supports scalable protection across multi‑machine assemblies in modern factories. Comprehensive documentation supports faster audits and safer operation: Tmax Ts3 data sheet, EC Declaration of Conformity, installation instructions, and wiring diagrams streamline training and compliance. The product’s UL 489 and CSA C22.2 certifications enable cross-border applicability in diverse manufacturing environments, reducing supplier risk, accelerating approval cycles for new lines, and simplifying spare-part alignment across global sites. Rugged construction with front-access terminals contributes to long service life and reduced downtime. Replacements and maintenance can be performed quickly with common hand tools, limiting production interruptions. For OEMs and system integrators, the ABB 1SDA065487R1 aligns with the Tmax ecosystem, enabling a scalable protection strategy across multiple machines, panels, and feeders while sustaining uptime and safety margins.
