<p>When selecting an Automatic Air Circuit Breaker (ACB) for industrial or commercial applications, the technical specifications hold paramount importance in ensuring reliability and safety. This particular ACB is designed to meet demanding electrical needs with precision and efficiency.</p><p>Rated for a current range between 1000 to 2500 Amperes, this ACB is versatile enough to handle various load requirements while maintaining optimal performance. Its rated voltage of 690 VAC ensures compatibility with standard industrial systems, making it a practical choice for diverse environments. The device&#39;s rated insulation voltage stands at 1000 VAC, providing robust protection against potential electrical faults.</p><p>With a rated impulse withstand voltage of 12 kV, this ACB is engineered to endure transient overvoltages without compromising its integrity. It boasts a formidable breaking capacity of 100 kA, which means it can safely interrupt high fault currents—an essential feature for safeguarding equipment and personnel from electrical hazards.</p><p>The Rated Short Time Withstand Current is an impressive 85 kA, enabling the circuit breaker to sustain high fault levels temporarily without tripping immediately. This characteristic allows time coordination with downstream protective devices, enhancing system selectivity and minimizing unnecessary outages.</p><p>Equipped with the Ekip Touch LSIG trip unit, this ACB offers advanced protection functionalities including Long-time (L), Short-time (S), Instantaneous (I), and Ground fault (G) protections. These features ensure comprehensive coverage against various types of faults while allowing customization according to specific application needs.</p><p>Designed with a frame size of E2.2 and featuring horizontal rear spread terminals, installation flexibility is ensured even in space-constrained switchgear assemblies. The four-pole configuration further extends its applicability across three-phase systems requiring neutral connectivity or isolation capabilities.</p><p>This product adheres strictly to IEC 309 standards—an assurance of compliance with international quality benchmarks that underscore its reliability and safety credentials in real-world operations.</p><p>Power loss in operation amounts to approximately 550 Watts—a consideration for thermal management within enclosures but indicative of efficient energy usage relative to its operational scope.</p><p>In summary, this Automatic ACB combines robust construction with advanced protective features tailored for modern industrial demands. Its adherence to stringent standards alongside flexible installation options makes it an ideal candidate for professionals seeking dependable circuit protection solutions tailored specifically towards Australian conditions where both performance metrics matter as much as adherence does too.</p>
