<p>In the realm of industrial and commercial electrical systems, selecting the right circuit breaker is crucial for ensuring safety and reliability. The non-automatic air circuit breaker (ACB) we&#39;re discussing here is designed to meet rigorous demands with a focus on performance and durability.</p><p>This ACB is engineered for a rated current of 2000 A, making it suitable for high-capacity applications where substantial power management is required. It operates effectively at a rated voltage of 690 VAC, providing robust protection in various industrial settings. The device&#39;s rated impulse withstand voltage stands at 12 kV, offering excellent resilience against transient overvoltages that can occur due to lightning strikes or switching surges.</p><p>Safety and insulation are paramount in electrical installations, and this product doesn&#39;t disappoint with its rated insulation voltage of 1000 V. This ensures reliable operation even under challenging conditions. Additionally, the degree of protection provided by its IP30 rating indicates that it&#39;s safeguarded against solid objects larger than 2.5 mm but not against water ingress—an important consideration depending on your installation environment.</p><p>The breaker features four poles which allow it to manage three-phase systems effectively while also accommodating neutral connections if needed. With dimensions of 407 mm in width, 425 mm in height, and a depth of 383 mm, this unit offers a compact footprint without compromising on functionality—a beneficial attribute when space constraints are present.</p><p>Power loss is an inevitable aspect of electrical components; however, this ACB manages it efficiently with a power loss rating of just 450 W. This efficiency translates into cost savings over time by minimizing wasted energy during operation.</p><p>Compliance with international standards is essential for any component integrated into critical systems. This product adheres to IEC 309 standards and approvals, ensuring it meets globally recognized benchmarks for safety and performance.</p><p>Weighing in at 55 kg, this ACB combines sturdy construction with manageable weight—a balance that simplifies installation while maintaining robustness necessary for demanding environments.</p><p>In summary, this non-automatic ACB delivers dependable performance tailored to high-current applications within industrial contexts. Its specifications align well with stringent operational requirements while adhering to key international standards—making it an ideal choice for engineers seeking reliability combined with practical design considerations.</p>
