<p>The Automatic Air Circuit Breaker (ACB) under discussion is a robust and reliable solution for industrial and commercial electrical systems. Designed to handle demanding environments, this ACB offers a rated current range between 1000 to 2500 A, making it versatile enough to cater to various load requirements.</p><p>One of the standout features of this ACB is its ability to withstand high impulse voltages, with a rated impulse withstand voltage of 12 kV. This ensures that the breaker can endure transient overvoltages without compromising performance or safety. Additionally, the rated insulation voltage stands at 1000 VAC, which provides an extra layer of protection against electrical faults.</p><p>For those concerned about short-circuit conditions, this ACB delivers peace of mind with its impressive breaking capacity and rated short-time withstand current both set at 66 kA. Such capabilities make it suitable for installations where high fault levels are expected.</p><p>The device operates efficiently within a system voltage up to 690 VAC. It incorporates the Ekip Touch LSIG trip unit, known for its precision in monitoring and protecting circuits through advanced settings like long-time, short-time, instantaneous, and ground fault protection functions.</p><p>In terms of design flexibility and integration into existing systems, this ACB features a horizontal rear spread terminal type. The four-pole configuration further enhances its adaptability across different applications by providing balanced load distribution among phases.</p><p>With power loss pegged at just 550 W during operation, this product ensures energy efficiency while maintaining operational reliability—a crucial factor in reducing overall energy costs in large-scale installations.</p><p>Conforming to IEC 309 standards and approvals assures users that the product meets international safety and performance benchmarks. This compliance underscores its suitability for global deployment where adherence to stringent regulations is mandatory.</p><p>Lastly, housed within an E2.2 frame size structure, this Automatic ACB combines compactness with durability—ideal for space-constrained environments without sacrificing robustness or functionality.</p>
