FAQs
For starters, use the fixed front-terminal connection to simplify wiring and service access in tight spaces. The 3P design fits standard 90 mm width enclosures with front-access terminals, and the device supports 500 V DC operation. Ensure proper rail mounting, verify clearance for heat dissipation, and follow installation instructions XT2 DC IEC for reliable protection.
The unit is rated for 20 A continuous current, 500 V DC operational voltage, and a short-circuit current rating of 36 kA (Ics and Icu) for 3P configurations. It withstands 8 kV impulse without breakdown and remains reliable under fault conditions, making it suitable for DC distribution in demanding environments.
Yes. With 3P configuration, front-terminal access, and a robust 36 kA fault current capability at 500 V DC, it is well-suited for DC distribution in motor control centers and control panels. Its compact XT2 design ensures easy integration into standard MCCs and panelboards while maintaining protection integrity.
It complies with IEC 60947-2 and GB/T 14028.2 standards, carries a CE declaration of conformity, and adheres to RoHS/REACH requirements. End-of-life documentation and ABB EcoSolutions support sustainable practices, including recyclability targets and disassembly guidance.
Ownership offers reduced wiring time thanks to front-terminal design, lower energy loss at 1.62 W per pole, and high mechanical durability (up to 25,000 cycles). These factors translate to faster commissioning, longer intervals between maintenance, and lower total cost of ownership in DC power protection applications.
