<p>When it comes to industrial and commercial electrical systems, reliability and efficiency are paramount. This non-automatic air circuit breaker (ACB) is a robust choice for those seeking dependable performance in high-demand environments. With a rated current of 2500 A, this ACB is designed to handle substantial electrical loads, making it suitable for various large-scale applications.</p><p>One of the key technical specifications of this product is its rated impulse withstand voltage of 12 kV. This feature ensures that the device can endure transient overvoltages, which are common in industrial settings, without compromising its integrity. Additionally, with a rated insulation voltage of 1000 V and a rated voltage of 690 VAC, this ACB provides ample protection against potential electrical faults.</p><p>Efficiency is further enhanced by its power loss rating of just 267 W. This low power loss not only contributes to energy savings but also minimizes heat generation within the system. The circuit breaker features three poles, offering balanced distribution across all phases in a three-phase system.</p><p>The degree of protection provided by an IP30 rating indicates that the unit offers protection against solid objects larger than 2.5 mm but does not protect against water ingress. Therefore, it&#39;s best suited for indoor installations where exposure to moisture isn&#39;t an issue.</p><p>Installation and maintenance are straightforward due to the bolt terminal type requiring a tightening torque of 70 N-m. The compact dimensions—276 mm in width, 371 mm in height, and 270 mm in depth—allow easy integration into existing panels or systems without requiring extensive modifications.</p><p>Compliance with IEC 309 standards underscores its quality and safety credentials, ensuring it meets international benchmarks for performance and reliability.</p><p>Weighing in at 41 kg, this ACB is sturdy yet manageable for installation teams familiar with handling equipment at this scale.</p><p>Overall, whether you&#39;re upgrading existing infrastructure or planning new installations, this non-automatic air circuit breaker promises durability and consistent performance tailored for demanding environments.</p>
