<p>In the world of industrial and commercial electrical engineering, choosing the right components for your system is crucial. The Non-automatic Air Circuit Breaker (ACB) you are considering offers a robust solution tailored for demanding environments, ensuring reliability and safety in power distribution.</p><p>With a rated current of 2000 A, this ACB is designed to handle substantial loads, making it suitable for large-scale applications where high performance is non-negotiable. Its rated insulation voltage stands at 1000 VAC, providing a strong barrier against potential electrical faults and enhancing overall system integrity.</p><p>The unit&#39;s rated impulse withstand voltage of 12 kV ensures that it can safely manage transient overvoltages often encountered in industrial settings. This feature helps protect sensitive equipment from unexpected spikes in voltage, thereby extending their operational lifespan.</p><p>A notable aspect of this breaker is its impressive breaking capacity of 100 kA. This capability allows it to interrupt fault currents effectively without damage to the system or itself, safeguarding both personnel and infrastructure from potentially hazardous situations.</p><p>Designed with a frame size of E2.2, the ACB fits seamlessly into existing setups while maintaining structural robustness. Its horizontal rear spread terminal type facilitates straightforward integration into various configurations, accommodating diverse installation requirements with ease.</p><p>Engineered to endure harsh conditions, the breaker boasts a rated short time withstand current of 85 kA. This attribute ensures that even under extreme fault conditions, the ACB remains functional long enough to allow protective devices upstream or downstream to clear the fault.</p><p>Energy efficiency is also considered with a power loss rating of just 450 W. Lower power losses translate into reduced heat generation within switchgear assemblies which aids in maintaining optimal operating temperatures and improving energy management across systems.</p><p>Compliance with IEC 309 standards underscores its quality and reliability as these standards are globally recognized benchmarks for safety and performance in electrical equipment design.</p><p>For professionals seeking an air circuit breaker that combines durability with high technical specifications suitable for rigorous applications within Australia’s diverse industrial landscape—this product provides an ideal balance between functionality and compliance without unnecessary complexity or cost implications associated with more advanced automatic variants.</p>
