<p>When it comes to ensuring the reliable protection and control of electrical circuits, choosing the right Air Circuit Breaker (ACB) is crucial. The Motor Operated ACB with a frame size of E4.2 offers a robust solution for industrial and commercial applications, balancing high performance with durability.</p><p>This device operates within a rated current range of 1280-3200 A, making it versatile for various operational needs. Its rated voltage stands at 690 VAC, which is suitable for most industrial environments. The breaker supports a rated insulation voltage of 1000 VAC and can withstand impulse voltages up to 12 kV, providing solid protection against unexpected electrical surges.</p><p>Safety is further enhanced by its impressive short time withstand current rating of 66 kA. This capability ensures that in the event of a fault or overload condition, the ACB can handle significant stress without compromising its integrity or safety.</p><p>The breaking capacity also matches this level at 66 kA, allowing it to effectively interrupt high fault currents and protect downstream equipment from damage. For those looking into energy efficiency metrics, this unit has a power loss specification of 743 W.</p><p>One standout feature is its Ekip Touch LSIG trip unit. This advanced electronic trip unit provides precise control over system parameters such as long-time (L), short-time (S), instantaneous (I), and ground fault (G) settings. Such versatility allows engineers to tailor protection strategies according to specific site requirements.</p><p>Designed with three poles and horizontal rear spread terminals, this ACB fits seamlessly into existing systems while maintaining ease of installation and maintenance access. Compliance with IEC 309 standards underscores its reliability and adherence to international quality benchmarks.</p><p>In summary, this Motor Operated ACB combines high-rated capacities with advanced trip functionality in one compact package—ideal for those seeking both performance assurance and operational flexibility in demanding environments.</p>
