ABB 1SDA123600R1 Moulded Case Circuit Breaker - 8 kV

Rated for 250 A and 750 V DC, the 1SDA123600R1 delivers dependable protection across four poles in a compact MCCB form. This enables safe, scalable protection for medium- to high-current DC feeders in automation, battery storage, and renewable energy installations. Release TM with TMA mechanism provides precise trip characteristics, while the Short-Circuit Performance Level X ensures rapid isolation of faults. In manufacturing lines and DC power networks, this translates to minimized arc duration and reduced downstream damage. Power loss of 16.44 W per pole under rated conditions reduces heat generation, supporting simpler cooling design and lower energy costs across panels and switchgear. The device’s mechanical durability—up to 25,000 cycles at 240 cycles/hour—supports high-demand environments and predictable maintenance planning. Installation is straightforward with fixed terminal connections, enabling faster panel mounting and reduced wiring errors. ABB EcoSolutions features, including disassembly instructions, EPD data, and recyclability guidance (56.3% EN45555), help meet sustainability and regulation targets. Compatibility with XT4 TM/TMA releases simplifies spare parts management and stock optimization for OEMs and panel builders. This device is well-suited for aerospace-grade control panels, industrial automation, and DC distribution in manufacturing and energy storage projects, delivering reliability, regulatory compliance, and lifecycle cost advantages.
