DC fixed three-pole XT2 design provides robust overcurrent protection for power distribution and DC drives. With a 63 A rating and 500 V DC operating voltage, it supports reliable protection in medium-to-heavy industrial panels, reducing fault-related downtime and enabling predictable maintenance cycles. Front terminals and fixed-circuit-breaker construction simplify wiring, minimize wiring errors, and speed panel assembly. In high-density control cabinets, this translates to shorter commissioning times and fewer field faults during installation. The TM release delivers precise overcurrent protection, with a clear trip characteristic that supports selectivity in multi-breaker architectures, reducing nuisance trips and protecting critical DC loads such as motors and drives while meeting fast-trip requirements. Rated impulses of 8 kV and an insulation voltage of 1000 V enable safe operation across a broad DC range, while IEC 60947-2 and GB/T 14028.2 standards ensure compatibility with global installations. The device is designed for 3P operation with a fixed terminal interface, easing standardization across multiple panels. Power loss of 4.85 W per pole keeps heat in check and contributes to cooler panel environments, and a mechanical durability rating of 25000 cycles supports long service life in continuous production lines. ABB EcoSolutions data and EN45555 recyclability figure of 55.7% help manufacturers meet sustainability targets and end-of-life requirements, including disassembly instructions for Tmax XT XT2 TM.
