The four-pole XT1 design with front terminals and TMD release reduces wiring complexity and improves fault isolation in compact switchgear. For panel builders, that means faster installation, fewer wiring errors, and safer service access during testing and maintenance; front-terminal accessibility also supports easier torque verification and quicker retrofits with a 6 N·m tightening torque per terminal. The 125 A rated current with an adjustable 87.5–125 A setting range enables precise protection coordination for feeders and downstream devices, reducing nuisance trips and optimizing downstream equipment life. With a rated voltage of 690 V and Icu up to 25 kA, this MCCB delivers robust short-circuit protection across typical industrial buses, minimizing downtime during faults. Compliance with IEC 60947-2, CE, RoHS and REACH standards streamlines procurement for multinational projects while supporting sustainability goals. Durability specs—25,000 mechanical cycles and 8,000 electrical cycles per hour—coupled with front‑terminal bolt connections (6 N·m torque) ensure reliable field performance and straightforward servicing in challenging environments. Busbar compatibility of 45.5–80 mm² and a weight of 1.4 kg further simplify enclosure layout and installation planning, making it a practical choice for modern switchboards.

FAQs
The ABB 1SDA066888R1 uses front-terminal connections designed for straightforward wiring within compact panels. Verify busbar sizing (45.5–80 mm²), ensure the mounting footprint matches XT1 dimensions, and tighten each terminal to 6 N·m. Use a main circuit screwdriver (M6) for secure torque and check that the unit sits firmly against the panel backplane to avoid inadvertent contact during maintenance.
The setting range for this unit is 87.5–125 A with a 125 A nominal rating. To adjust, rotate the setting dial within the approved range and verify the position with a calibrated test. Coordinating the setting with downstream protective devices reduces nuisance trips and aligns protective curves with feeder load profiles in transformer and distribution panels.
The device provides high fault protection with a Rated Ultimate Short-Circuit Breaking Capacity (Icu) up to 25 kA and a Rated Service Short-Circuit Breaking Capacity (Ics) suitable for multiple voltages, including 220–240 V variants. With a rated voltage of 690 V and a 4P configuration, it protects feeders and transformers against severe faults while maintaining system reliability.
Yes. The MCCB adheres to IEC 60947-2 and bears CE conformity. It also supports RoHS and REACH declarations, enabling compliance across global supply chains. Additional documentation covers DoCs, environmental declarations, and recyclable packaging, supporting sustainability targets and regulatory requirements in multinational installations.
The unit measures 101.6 mm width by 130 mm height and 70 mm depth, with a weight of 1.4 kg. It is designed for front-terminal, bolt-type connections and 6 N·m tightening torque. Compatible busbars range from 45.5 to 80 mm², and the unit is suited for SACE Tmax XT switchgear, simplifying installation in modern distribution boards and transformer feeders.
