ABB 1SDA116346R1 Moulded Case Circuit Breaker - 50 kA Ics

The device delivers a 250 A rated current in a 4P configuration, designed to protect large feeders and three-phase motors without nuisance tripping during inrush. This translates to higher machine uptime, fewer production interruptions, and simpler coordination with upstream protection schemes, reducing the risk of cascading faults. Ideal for panel builders and OEMs deploying P2 networks in automation cells, conveyors, and processing lines where reliable protection and compact form factor matter. Setting Range of 175–250 A enables adjustable protection thresholds and tailored trip curves. This enables selective tripping, smoother commissioning, and reduced spare parts for reconfiguration as loads evolve. Suitable for machine tools, robot cells, and packaging lines where loads vary with throughput and seasonality. Short-circuit ratings Ics = 50 kA (240 V AC) and Icu = 36 kA, with Ui = 750 V and Ur = 500 V AC / 250 V DC, provide strong fault-limiting performance across multiple voltages. This minimizes damage to busbars, transformers, and cables while enabling safe isolation during faults. Industrial automation panels that combine AC and DC segments benefit from this robust protection. Mechanical Durability up to 20000 cycles and a front-terminal connection simplify installation and maintenance. This extends service life, lowers field service time, and reduces lifecycle costs, especially in high-cycle environments like sorting, packaging, and continuous process lines. Panel assemblies in manufacturing plants requiring rapid replacement and minimal downtime gain from these features. Comprehensive compliance including RoHS, REACH, CMRT, TSCA declarations and WEEE packaging information supports global procurement. This reduces regulatory risk, accelerates audits, and streamlines international sourcing. Global rollouts across regional supply chains and multi-site automation installations benefit from these certifications and disclosures.
