FAQs
1SDA065479R1 is a fixed two-pole MCCB with front terminals designed for standard panel cutouts used in distribution boards and machine controls. It supports typical DIN rail layouts in panel assemblies and aligns with Tmax series mounting patterns, enabling straightforward replacement or upgrades in existing ABB systems.
The device provides protection across a 20 to 500 A current range, suitable for motor drives, feeders, and protected branches. The thermomagnetic TMF release delivers fast fault isolation during short circuits while providing overload protection within the rated window. The 2-pole design ensures balanced protection and simplifies coordination with upstream devices.
This MCCB complies with UL 489 and CSA C22.2 for North American use, carries a CE Declaration of Conformity under Tmax Ts3, and carries WEEE Category 5 labeling for end-of-life management. The data sheet references Tmax Ts3L generation and front-terminal configuration, supporting regulated electrical protection in industrial environments.
TMF thermomagnetic release responds quickly to magnetic short-circuit faults and provides reliable thermal protection during overloads, delivering fast trip action and reducing arc energy. This results in higher equipment uptime, safer maintenance windows, and better protection coordination with upstream devices.
Front-terminal design simplifies wiring, reduces panel depth requirements, and speeds installation in crowded switchboards. It also eases inspection and replacement, minimizes wiring errors, and supports cleaner, low-profile panels—especially valuable in compact control panels or machine enclosures.
