<p>For professionals in the electrical engineering and automation sectors, selecting the right Automatic Air Circuit Breaker (ACB) is crucial for ensuring reliable power distribution and protection. This particular ACB offers a robust solution with its mid-range specifications tailored to meet diverse industrial and commercial needs.</p><p>With a rated current spanning from 800 to 2000 Amperes, this ACB is versatile enough to handle varying load demands efficiently. It operates at a rated voltage of up to 690 VAC, making it suitable for high-power applications typical in industrial environments. The device&#39;s rated impulse withstand voltage stands at an impressive 12 kV, providing significant resilience against transient overvoltages.</p><p>Engineered with safety in mind, this ACB boasts a breaking capacity of 66 kA. This ensures that it can effectively interrupt fault currents without compromising system integrity or operator safety. The rated short time withstand current also matches this value at 66 kA, underscoring its capability to manage short-circuit conditions reliably.</p><p>The product features the Ekip Touch LSIG trip unit, which provides advanced protection functions including long-time (L), short-time (S), instantaneous (I), and ground fault (G) protections. This comprehensive suite of protective measures helps maintain system stability while minimizing downtime during fault conditions.</p><p>In terms of construction, the ACB has a frame size classified as E2.2 and comes equipped with three poles. Its horizontal rear spread terminal type facilitates straightforward installation and maintenance within existing switchgear setups.</p><p>Power loss is often a concern in circuit breakers due to heat generation; however, this model maintains efficiency with a power loss rating of just 450 W. Such efficiency contributes not only to energy savings but also prolongs the lifespan of surrounding components by reducing thermal stress.</p><p>Compliance with IEC 309 standards further assures users that this ACB meets international safety and performance benchmarks essential for peace of mind in critical applications.</p><p>Whether you&#39;re upgrading existing systems or designing new installations, this Automatic ACB combines reliability with functional flexibility—key attributes for any professional tasked with managing complex electrical infrastructures within Australia’s demanding industrial landscape.</p>
