<p>When selecting an Automatic Air Circuit Breaker (ACB) for your industrial or commercial needs, understanding the technical specifications is crucial. This ACB model is designed to handle demanding electrical environments with a rated current of 630 A, ensuring robust performance in various applications.</p><p>The rated impulse withstand voltage stands at 12 kV, offering excellent protection against transient overvoltages typically caused by lightning strikes or switching operations. Coupled with a rated insulation voltage of 1000 V and a rated operational voltage of 690 VAC, this breaker is well-equipped to manage high-voltage scenarios safely.</p><p>Equipped with an EL release type and an Ekip Touch LSIG trip unit, this ACB provides advanced protection features including overload (L), short-circuit (S), instantaneous (I), and ground fault protection (G). These features are essential for maintaining system integrity and preventing damage to connected equipment.</p><p>Power efficiency is also considered with a power loss of only 31 W during operation. The breaker supports front connection types for ease of installation and maintenance. It has three poles and boasts a substantial breaking capacity of 50 kA, making it suitable for high fault level applications.</p><p>The degree of protection is IP30, which means it offers basic protection against solid objects larger than 2.5 mm but isn&#39;t waterproof; thus it&#39;s ideal for indoor use where moisture exposure is minimal. The bolt terminal type ensures secure connections that can withstand vibrations common in industrial settings.</p><p>For installation specifics, the tightening torque required is set at 45 N-m to ensure optimal contact pressure without damaging components. Dimensionally compact yet robustly built, the breaker measures 210 mm in width, 296 mm in height, and has a depth of 183 mm—facilitating easy integration into existing panels or enclosures.</p><p>Conforming to IEC 309 standards ensures compliance with international safety regulations which are critical when operating within diverse global markets like Australia’s. With a weight of just 14 kg, handling during installation or maintenance remains manageable without compromising on durability or performance.</p><p>In summary, this Automatic ACB combines high-performance characteristics with reliable safety features tailored for both industrial and commercial applications requiring dependable circuit protection solutions under stringent conditions.</p>
