<p>When it comes to industrial and commercial electrical systems, selecting the right equipment is crucial for ensuring safety, efficiency, and reliability. The Motor Operated Air Circuit Breaker (ACB) described here is engineered to meet these stringent demands with precision. </p><p>This ACB is designed for a broad range of applications with a rated current spanning from 1280 A to 3200 A, making it versatile enough for various industrial settings. It operates at a rated voltage of 690 VAC and offers an impressive breaking capacity of 100 kA. These specifications ensure that the circuit breaker can handle significant electrical loads while maintaining stability and protection in your electrical systems.</p><p>Safety standards are paramount in any electrical installation, and this product adheres to IEC 309 standards, assuring compliance with international safety requirements. With a rated impulse withstand voltage of 12 kV and an insulation voltage of up to 1000 VAC, this ACB provides robust protection against voltage surges and insulation failures.</p><p>The unit features an Ekip Touch LSIG trip unit which enhances its functionality by offering advanced protection features such as long-time (L), short-time (S), instantaneous (I), and ground fault (G) protections. This ensures that any anomalies in the system are detected promptly, minimizing potential damage or downtime.</p><p>From a structural perspective, the ACB boasts a frame size of E4.2 which accommodates its operational capabilities while maintaining compactness for easier installation within existing setups. The horizontal rear spread terminal type further facilitates integration into your infrastructure without extensive modifications.</p><p>One notable aspect is its ability to handle extreme conditions with a rated short time withstand current of up to 85 kA. This capability ensures that even during severe fault conditions, the breaker maintains integrity without compromising safety or performance.</p><p>Moreover, power loss is always a consideration in high-capacity devices; this model registers at just 743 W under operation—a testament to its efficiency in energy use without sacrificing performance.</p><p>With four poles included in its design, this breaker provides comprehensive coverage across phases—ideal for balanced load distribution in three-phase systems often found in commercial operations.</p><p>In summary, whether you&#39;re upgrading existing installations or planning new projects requiring reliable circuit interruption solutions capable of handling substantial currents safely over time frames both long-term steady-state usage as well short-circuit events—the Motor Operated ACB detailed here stands out as an excellent choice balancing technical prowess alongside practical usability within demanding environments where dependability cannot be compromised.</p>
