<p>When it comes to ensuring reliability and safety in electrical systems, selecting the right automatic air circuit breaker (ACB) is crucial. This particular ACB model stands as a robust choice for industrial and commercial applications, offering a blend of performance, durability, and compliance with international standards.</p><p>Designed for versatility, this ACB accommodates a rated current range from 1000 to 2500 A. It operates efficiently within these parameters, making it suitable for various load demands without compromising on performance. The device&#39;s rated voltage of 690 VAC ensures compatibility with standard power systems.</p><p>Safety and resilience are at the forefront of its design. With a rated impulse withstand voltage of 12 kV, this ACB can handle transient over-voltages effectively. Furthermore, its rated insulation voltage is set at 1000 VAC, providing an additional layer of protection against electrical faults.</p><p>In terms of short-circuit handling capabilities, this ACB impresses with a breaking capacity of 100 kA and a rated short-time withstand current of 85 kA. These features ensure that the circuit breaker can safely interrupt high fault currents without sustaining damage or causing system failures.</p><p>The trip unit incorporated in this model is the Ekip Touch LSIG type. This advanced unit offers precise protection settings—covering long-time (L), short-time (S), instantaneous (I), and ground fault (G) scenarios—providing comprehensive coverage for various fault conditions.</p><p>From an efficiency standpoint, the power loss associated with this ACB is measured at 550 W. While power loss is inevitable in any circuit breaker operation due to internal resistance during conduction periods, maintaining it at this level aids in minimizing energy wastage across extended operations.</p><p>Structurally designed with four poles and housed within an E2.2 frame size, installation flexibility is enhanced through its horizontal rear spread terminal configuration. This setup facilitates straightforward integration into existing panels or new installations while optimizing space usage.</p><p>Complying with IEC 309 standards underscores its commitment to quality assurance and adherence to globally recognized safety benchmarks—a critical factor when evaluating equipment for sensitive environments where reliability cannot be compromised.</p><p>This automatic air circuit breaker thus represents a balanced approach between technical capability and operational practicality—ideal for professionals seeking dependable solutions tailored toward demanding electrical landscapes where precision control over complex networks remains paramount.</p>
