FAQs
ABB 1SDA074816R1 uses a front-terminal XT2 format and 4P configuration, designed for straightforward retrofit into existing panels. It supports busbars from 32.5 to 100 mm² and requires a tightening torque of 6 N·m, ensuring reliable, repeatable connections. This compatibility minimizes wiring changes and speeds up commissioning in upgrades.
Verify rated current of 125 A, adjustable I_i range of 625–1250 A, rated voltage of 600 V AC / 500 V DC, and four-pole front-terminal construction. Confirm declaration of conformity and UL/CSA listings, including UL certificate 1SDL000163R0112 and CSA certificate 9AKK10103A3906, to ensure regulatory compliance for the target installation.
Industrial manufacturing lines, process industries, and data center power distribution benefit most, where reliable overcurrent protection and swift fault clearing are essential. Applications include feeders for motors, drives, and mixed AC/DC circuits, with space-constrained panels requiring compact, modular protection devices from the SACE Tmax XT family.
This model carries UL489 and CSA certifications, CE declaration of conformity, UL certificate 1SDL000163R0112, and RoHS/REACH declarations. It also provides environmental data such as EPD and 55.70% recyclability per EN45555. These certifications streamline procurement and support sustainability and compliance in regulated markets.
Maintenance revolves around periodic inspection of terminal connections (6 N·m torque), cleaning of front-terminal interfaces, and monitoring heat rise in panels due to 11.4 W per pole losses. ROI benefits come from reduced downtime, lower panel heat, streamlined spare parts inventory, and alignment with end-of-life recycling programs, thanks to the device’s environmental data and reusable components.
