FAQs
Yes. This unit uses Fixed Circuit-Breakers terminals and a 4P configuration, making it compatible with standard 4P MCCB slots and common cabinet layouts. With dimensions of 186 mm wide, 205 mm high, and 103 mm deep, it fits into mid-sized to large control cabinets. Ensure enclosure clearance for wiring harnesses and confirm compatibility with your rail and cable routing.
The MCCB is rated for In 500 A and Ui 1000 V, with a rated insulation voltage of 1000 V and rated impulse withstand voltage of 8 kV. Short-circuit performance is up to 50 kA for two poles in series (250 or 500 V DC) or three poles in series (750 V DC). Uninterrupted current Iu is 630 A, supporting substantial continuous DC loads.
Absolutely. With 4P DC-rated protection, TM/TMA release, and high short-circuit capacity, it is well-suited for motor drives, battery charging circuits, and other high-DC-load applications within manufacturing and process automation. The 750 V DC operating voltage and 630 A Iu provide the reliability needed for continuous production lines.
This MCCB complies with IEC 60947-2 and GB/T 14028.2, and carries CE conformity along with RoHS and REACH declarations. ABB EcoSolutions offers end-of-life and environmental data, including disassembly guidance and packaging disposal information, enabling clearer regulatory alignment and sustainable procurement.
The unit offers 20,000 mechanical durability cycles and documented end-of-life disassembly instructions, reducing maintenance downtime and disposal complexity.
