<p>When selecting an Automatic Air Circuit Breaker (ACB) for your industrial or commercial setup, understanding the technical specifications is crucial. This particular ACB model is designed with a focus on reliability and efficiency, making it a suitable option for various applications.</p><p>At its core, this ACB handles a rated current of 1250 A, ensuring it can manage significant electrical loads effectively. The rated voltage stands at 690 VAC, which caters well to high-demand environments. Its robust design includes a breaking capacity of 42 kA, providing confidence in its ability to interrupt fault currents safely without compromising system integrity.</p><p>Safety and durability are underscored by the rated impulse withstand voltage of 12 kV and a rated insulation voltage of 1000 V. These features are critical for protecting against transient overvoltages and ensuring long-term operation under demanding conditions.</p><p>The trip unit incorporated in this model is the Ekip Touch LSI release type EL. It offers precise control over tripping functions, enhancing protection through advanced monitoring capabilities. This ensures that your system remains safeguarded against overloads and short circuits with minimal intervention required.</p><p>In terms of physical dimensions, this ACB measures 278 mm in width, 363.5 mm in height, and 271 mm in depth—compact enough to fit into standard panels while still offering substantial performance capabilities. With an IP30 degree of protection rating, it&#39;s well-suited for indoor applications where dust ingress needs to be minimized but not entirely sealed from moisture exposure.</p><p>Power loss is another consideration when evaluating circuit breakers; this model has a power loss rating of 244 W—indicative of efficient energy management within its operational scope. Weighing in at 18 kg, it’s relatively lightweight given its robust feature set.</p><p>Compliance with IEC 309 standards further assures users that this ACB meets rigorous international safety and performance benchmarks—a non-negotiable aspect for many engineers seeking reliable components for their systems.</p><p>Overall, if you require an automatic circuit breaker that balances technical prowess with practical application needs across industrial settings without unnecessary complexity or bulkiness—this could be the right choice for you.</p>
