The 1SDA123518R1 uses a four-pole configuration with fixed front-terminal connections to deliver reliable DC protection in compact enclosures, which reduces wiring complexity and speeds up installation. Business impact: faster project commissioning and lower field wiring errors, enabling more predictable maintenance windows in automation lines. Application: ideal for DC distribution in conveyor drives, robotics, and automated machinery where space is limited and reliability is critical. The device delivers a rated current of 160 A and a rated operational voltage of 500 V DC, ensuring compatibility with medium‑voltage DC busbars while meeting stringent IEC 60947-2 requirements. The 8 kV rated impulse withstand and 36 kA short-circuit capabilities (Ics/Icu) at respective voltages translate to robust fault containment and minimized downtime. Power loss of 16.15 W per pole supports thermal management without excessive cooling requirements, improving overall energy efficiency. Mechanical durability of 25,000 cycles supports long service life in high‑duty environments, reducing replacement costs and spare part waste. The release is TMA with TM type, offering predictable tripping behavior under overload and fault conditions. End‑of‑life disassembly guidance and a clear recycling pathway are provided to simplify lifecycle management and regulatory compliance. The design aligns with ABB EcoSolutions for sustainability targets, while front-terminal accessibility accelerates servicing and fault isolation. These aspects collectively enhance safety, regulatory compliance, and total cost of ownership for industrial DC protection schemes.
