<p>When selecting a motor-operated air circuit breaker (ACB) for your industrial or commercial application, it&#39;s crucial to consider the technical specifications that align with your operational needs. This particular ACB offers a robust solution with its impressive range of features and capabilities.</p><p>The rated current for this ACB spans from 1600 to 4000 amperes, providing flexibility across various applications where different load requirements might be encountered. The device is designed to handle high power demands while maintaining efficiency and safety.</p><p>With a rated impulse withstand voltage of 12 kV, this ACB is well-equipped to manage transient over-voltages that can occur in electrical systems. Additionally, the rated insulation voltage stands at 1000 VAC, ensuring reliable performance under standard operating conditions.</p><p>This model excels in short-circuit scenarios thanks to its rated short-time withstand current and breaking capacity both set at an impressive 66 kA. Such specifications ensure it can effectively protect circuits by interrupting fault currents swiftly and safely.</p><p>Operating at a rated voltage of 690 VAC, this ACB is suitable for medium-voltage applications commonly found in industrial settings. It features an Ekip Touch LSIG trip unit which provides advanced protection functionalities including overload (L), short-circuit (S), instantaneous (I), and ground fault (G) protections—essential for safeguarding both equipment and personnel.</p><p>The power loss associated with this unit is measured at 900 watts. While all electrical devices incur some level of power loss during operation, knowing this figure helps you calculate energy efficiency within your system design.</p><p>Designed with three poles, the ACB ensures consistent distribution of electricity across phases in three-phase systems—a common configuration in industrial environments. The frame size of E4.2 indicates its physical dimensions are optimized for space-saving installations without compromising on performance or reliability.</p><p>Featuring horizontal rear spread terminals, installation becomes straightforward as it allows efficient connections within switchgear assemblies or panels—ideal when space constraints are present or when retrofitting existing setups.</p><p>Compliance with IEC 309 standards underscores the product&#39;s adherence to international quality and safety benchmarks—a reassuring factor when integrating into critical infrastructure projects where reliability cannot be compromised.</p><p>This motor-operated ACB stands out as a dependable choice offering substantial protective measures necessary for demanding electrical networks frequently faced by Australian industries today.</p>
