<p>When considering robust and reliable solutions for industrial and commercial electrical systems, the non-automatic air circuit breaker (ACB) presented here is a noteworthy choice. Designed with precision to meet demanding requirements, this ACB offers a rated current of 6300 A, making it suitable for high-capacity applications where performance consistency is key.</p><p>One of the standout features of this product is its rated impulse withstand voltage of 12 kV. This specification ensures that the device can handle significant voltage spikes without compromising its integrity, which is crucial in environments prone to electrical surges. Complementing this is its rated insulation voltage of 1000 V, providing an additional layer of safety and reliability.</p><p>Operating at a rated voltage of 690 VAC, this ACB fits seamlessly into various power distribution systems. It efficiently manages power with a specified power loss of 1550 W. While power loss might seem like a minor detail, understanding it helps in assessing the overall efficiency and thermal management within your system setup.</p><p>The ACB comes equipped with three poles, offering balanced load distribution across phases—a critical aspect when dealing with large-scale electricity management tasks. Additionally, its IP30 degree of protection indicates that while it&#39;s protected against solid objects over 2.5 mm in size (like small tools or wires), it&#39;s not sealed against water ingress—something to consider based on installation environment needs.</p><p>In terms of physical dimensions, the breaker measures 803 mm in width, 425 mm in height, and has a depth of 383 mm. These measurements ensure that it can be accommodated within standard panel designs without requiring significant modifications—an important consideration during retrofits or upgrades.</p><p>Weighing in at 120 kg, handling during installation should be planned accordingly to ensure safety and ease. The adherence to IEC standards (IEC 309) further underscores its compliance with international safety norms—reassuring users about quality and performance benchmarks.</p><p>This non-automatic ACB represents a blend of technical prowess and practical design considerations aimed at delivering dependable service across varied industrial settings. Its specifications make it well-suited for professionals seeking equipment that aligns with stringent operational demands while maintaining compliance with recognized industry standards.</p>
