ABB 1SDA116375R1 Moulded Case Circuit Breaker - IEC

Setting Range and current carrying capability: The 280–400 A setting range lets you tailor protection to load profiles without oversizing. This reduces nuisance trips and optimizes selective coordination across feeders, improving energy management and maintenance planning. Ideal for main distribution panels in manufacturing lines and critical automation cabinets. Rated voltage and insulation: With rated voltage 500 VAC / 250 V DC and insulation suitable for 750 V, it supports mixed AC/DC environments. This improves safety margins and reduces the need for multiple devices in cross-category installations, especially in motor control centers and panel boards in process automation. Short-circuit and interrupt capabilities: Ics up to 50 kA at 240 V AC and 36 kA–50 kA across higher voltages, with Icu up to 50 kA (AC) and 25 kA (DC). These ratings enable robust fault handling in demanding production lines and critical power feeds, reducing the risk of collateral damage. Mechanical durability and form factor: 15,000 cycles at 24 cycles/hour and a 4P configuration support long service life in high-demand environments, minimizing replacement costs and downtime in distribution cabinets. Compliance and traceability: RoHS, REACH, CMRT, and TSCA declarations support straightforward audits and regulatory reporting, while EAN 8056221084833 ensures precise procurement and inventory control for panel builders. Installation and compatibility: Front-terminal connection and compact dimensions (186 mm width, 205 mm height, 103 mm depth) enable easy integration into existing enclosures and modular busbar layouts, reducing commissioning time and installation risk.
