<p>When selecting the right air circuit breaker (ACB) for your industrial or commercial needs, it&#39;s crucial to focus on the specifications that directly impact performance and safety. The Non-automatic ACB detailed here is designed to meet rigorous demands with a rated current of 3200 A, making it suitable for high-capacity electrical systems. Its robust design ensures reliability in various applications.</p><p>One of the standout features is its rated impulse withstand voltage of 12 kV, offering substantial protection against transient over-voltages often encountered in industrial settings. Complementing this is a rated insulation voltage of 1000 V, which provides an additional layer of security by ensuring safe operation under normal conditions.</p><p>Operating at a rated voltage of 690 VAC, this ACB can handle substantial power loads typical in large-scale operations. Despite its powerful capabilities, it maintains efficient energy use with a power loss rating of only 425 W—an important consideration for those monitoring energy consumption and efficiency.</p><p>The unit&#39;s construction includes four poles and an IP30 degree of protection, safeguarding internal components from dust ingress while ensuring user safety. The bolt-type terminals are engineered for secure connections, requiring a tightening torque of 70 N-m to maintain optimal contact integrity throughout its operational life.</p><p>In terms of dimensions, this ACB measures 510 mm in width, 371 mm in height, and 270 mm in depth—a compact footprint considering its capacity. Weighing in at 70 kg, it&#39;s manageable within standard installation procedures yet sturdy enough to withstand demanding environments.</p><p>Adhering strictly to IEC 309 standards and approvals guarantees compliance with international benchmarks for quality and safety—a testament to its reliability across diverse applications. Whether you&#39;re upgrading existing infrastructure or planning new installations, these specifications ensure compatibility with industry requirements while providing peace-of-mind performance.</p><p>Ultimately, when evaluating whether this non-automatic ACB fits your technical needs, consider how each specification aligns with your system&#39;s demands—from current ratings to physical dimensions—and rest assured knowing you’re supported by proven standards like IEC compliance.</p>
