<p>When considering the integration of an Automatic Air Circuit Breaker (ACB) into your industrial or commercial electrical system, it&#39;s essential to rely on solid technical specifications. This ACB is designed for robust performance and reliability, meeting a variety of demanding applications.</p><p>With a rated current of 4000 A, this ACB is capable of handling substantial electrical loads, making it suitable for large-scale operations. Its rated impulse withstand voltage at 12 kV ensures resilience against transient overvoltages, providing protection to your system from lightning strikes and other surge events.</p><p>The breaker operates at a rated insulation voltage of 1000 V and supports a maximum operating voltage of 690 VAC. These parameters indicate its capability to function effectively in high-voltage environments while maintaining safety standards. The release type is EL, paired with the Ekip Touch LSIG trip unit, offering comprehensive protection by covering long-time (L), short-time (S), instantaneous (I), and ground fault (G) conditions.</p><p>A critical aspect when selecting an ACB is its power loss rating; this model has a power loss of 900 W. While ensuring operational efficiency, it minimizes energy wastage which can be crucial in reducing overall operational costs over time.</p><p>This ACB features four poles, allowing it to manage three-phase systems with neutral connectivity efficiently. With a breaking capacity of 66 kA, it provides reliable interruption capability during fault conditions—ensuring that even significant faults can be interrupted safely without causing damage to the equipment or posing risks to personnel.</p><p>The device&#39;s degree of protection is IP30, indicating basic protection against solid objects larger than 2.5 mm but not against water ingress—a consideration for installation environments where exposure might occur.</p><p>In terms of physical dimensions: the width measures at 551 mm, height at 425 mm, and depth at 383 mm. These compact dimensions allow for versatile installation options within standard panel enclosures without compromising on space efficiency. Weighing in at 74 kg signifies its sturdy construction yet manageable weight for handling during installation processes.</p><p>Compliance with IEC Standard 309 underscores its adherence to international safety and performance criteria—ensuring peace of mind regarding quality assurance and interoperability across global markets.</p><p>Overall, this Automatic ACB offers robust functionality tailored for heavy-duty requirements while ensuring compliance with stringent standards—making it an ideal choice for those seeking reliability combined with advanced protective features in their electrical systems.</p>
