<p>When it comes to selecting a reliable and robust non-automatic air circuit breaker (ACB) for industrial or commercial applications, understanding the technical specifics is crucial. This particular ACB offers a dependable solution with its substantial rated current of 5000 A, making it suitable for high-demand electrical environments.</p><p>Operating at a rated voltage of 690 VAC, this ACB ensures efficient performance across various applications. The rated insulation voltage stands at 1000 V, providing an extra layer of safety by preventing unwanted electrical discharge. Furthermore, its rated impulse withstand voltage of 12 kV highlights its capability to handle transient overvoltages without compromising system integrity.</p><p>The device is designed with three poles and adheres to IEC 309 standards and approvals, ensuring compliance with international safety regulations. This makes it a trustworthy component in global markets where adherence to stringent standards is mandatory.</p><p>In terms of physical specifications, the unit measures 803 mm in width, 425 mm in height, and has a depth of 383 mm. Despite its considerable size, the design optimizes space within electrical panels while maintaining ease of installation and maintenance. Weighing in at 120 kg, it&#39;s sturdy enough to withstand operational stresses while remaining manageable during setup.</p><p>The degree of protection offered by this ACB is IP30. This indicates that the unit provides protection against solid objects greater than 2.5 mm but does not offer water protection—an important consideration when planning for environmental conditions where additional enclosure might be necessary.</p><p>Efficiency is further emphasized with a power loss rating of just 850 W—a critical factor for energy-conscious operations aiming to minimize heat generation and maximize energy use efficiency within their systems.</p><p>Overall, this non-automatic ACB delivers on multiple fronts: high current handling capability paired with rigorous safety standards make it an optimal choice for those seeking reliability without compromise on quality or performance metrics.</p>
