<p>When selecting a reliable circuit breaker for industrial or commercial applications, the non-automatic Air Circuit Breaker (ACB) with a rated current of 2000 A stands out as a robust choice. Designed to meet demanding electrical requirements, this ACB ensures operational safety and efficiency.</p><p>This unit is engineered to handle high power demands effectively. It boasts a rated impulse withstand voltage of 12 kV, making it suitable for environments where transient overvoltages are common. The rated insulation voltage of 1000 V further enhances its capability to operate in challenging conditions, offering an added layer of protection against electrical faults.</p><p>Operating at a rated voltage of 690 VAC, this ACB is versatile enough for various industrial applications. Its four-pole configuration provides comprehensive coverage across all phases, ensuring balanced load distribution and enhanced system stability.</p><p>In terms of energy efficiency, the product has a power loss rating of 450 W. This specification indicates that while it handles significant electrical loads, it does so with minimal energy wastage—an important consideration for operations looking to optimize their energy consumption.</p><p>The degree of protection offered by this ACB is IP30. This level of ingress protection ensures that the device is safeguarded against solid foreign objects larger than 2.5 mm but isn&#39;t protected against water ingress—a factor worth considering based on your installation environment.</p><p>From a physical standpoint, the dimensions are compact yet substantial: with a width of 407 mm, height of 425 mm, and depth of 383 mm. These measurements make it feasible to install in varied settings without compromising on space or accessibility.</p><p>Complying with IEC 309 standards and approvals underscores its adherence to international safety and performance criteria—reassuring users about its reliability in critical applications. With a weight of 55 kg, this ACB offers robustness without being overly cumbersome during installation or maintenance processes.</p><p>Overall, if you require an air circuit breaker that combines high performance with compliance to stringent standards while maintaining operational integrity under heavy-duty conditions—this model presents itself as an ideal candidate for your needs.</p>
