FAQs
ABB 1SDA074650R1 uses front-terminal bolt connections and a 6 N·m tightening torque, designed for easy, secure installation in cabinets and switchboards. Ensure the busbar width accommodates 45.5 to 80 mm² conductors and verify clearance for four-pole mounting. The compact XT1N footprint simplifies serviceability and replacement without disturbing adjacent components.
Key specs include 20 A nominal current, 125 A rated operational current (Iu), 600Y/347 V AC and 500 V DC ratings, four poles, TMF release, UL489 standard, and interrupting capacities up to 50 kA at 240 V, 25 kA at 480 V, with 18 kA at 600Y/347 V. It uses front-terminal connections for reliable fault interruption in mixed-voltage installations.
Yes. The four-pole TMF‑release MCCB provides selective protection for motor feeders and buses. The 20 A rating covers control circuits and downstream protections, while the Iu capability allows continued operation during maintenance. Its compatibility with the SACE Tmax XT family supports standardized motor protection across panels and upgrade projects.
The device carries UL489 and CSA CS22.2 listings, with a CE Declaration of Conformity and RoHS compliance. Documentation includes DoC and product data sheets, plus end-of-life, environmental, and recycling information. These certifications support compliance in global installations and supplier qualification programs.
The MCCB offers reduced downtime through reliable protection and fast serviceability, minimizing cascading faults. Front-terminal mounting speeds installation and retrofits, while standardization within the SACE Tmax XT family lowers inventory and training costs. Over the life of a facility, this translates to lower maintenance labor, shorter outages, and predictable procurement costs.
