<p>When it comes to industrial electrical systems, ensuring reliability and safety is paramount. The Automatic Air Circuit Breaker (ACB) in discussion here is a robust choice for those needing a dependable solution for high-capacity power distribution. Designed with precision, this ACB caters to the demanding requirements of both commercial and industrial environments.</p><p>With a rated current range from 1600 to 4000 A, this circuit breaker offers versatility for various applications. Its impressive rated impulse withstand voltage of 12 kV ensures that it can handle transient voltages effectively, providing protection against surges. Additionally, the rated insulation voltage stands at 1000 VAC, supporting its capability to operate safely under high voltage conditions.</p><p>One notable feature of this ACB is its substantial rated short time withstand current of 85 kA. This specification highlights the breaker&#39;s ability to endure significant fault currents over a brief period without sustaining damage. Coupled with its breaking capacity of 100 kA, it provides assurance in managing unexpected overloads or faults efficiently.</p><p>The Ekip Touch LSIG trip unit integrated into this circuit breaker enhances operational control with advanced protection functions including long-time (L), short-time (S), instantaneous (I), and ground fault (G) protections. This comprehensive suite allows users to tailor settings according to specific system needs while optimizing safety and performance.</p><p>Constructed with a frame size of E4.2, the ACB fits seamlessly into existing setups requiring similar dimensions. Its four-pole configuration further expands its applicability across diverse electrical architectures by facilitating balanced load distribution and effective fault isolation.</p><p>Power efficiency is another strength; despite its capabilities, it incurs a power loss of just 900 W during operation—an important factor when considering overall energy management in large installations.</p><p>Installation flexibility is provided by the horizontal rear spread terminal type which simplifies integration into existing panels or switchboards without extensive modifications—a practical advantage for upgrades or retrofits.</p><p>Adherence to IEC 309 standards underscores the product&#39;s compliance with international quality and safety benchmarks, reassuring users of its reliability in critical applications.</p><p>In summary, this Automatic ACB combines technical excellence with practical design features suitable for rigorous industrial use cases where reliability cannot be compromised.</p>
