<p>When considering an Automatic Air Circuit Breaker (ACB) for your industrial or commercial needs, it&#39;s essential to focus on the technical specifications that ensure reliability and efficiency. This ACB is designed to meet rigorous standards while providing robust protection and control.</p><p>With a rated current of 1000 A, this ACB is well-suited for medium to large-scale electrical systems. It supports a rated voltage of 690 VAC, making it versatile for various applications within industrial settings. The rated impulse withstand voltage stands at 12 kV, ensuring resilience against transient overvoltages typically caused by lightning strikes or switching surges.</p><p>The breaker features a release type EL with an Ekip Touch LSI trip unit, which allows precise adjustments to suit specific operational requirements. This functionality ensures that the system can handle overloads and short circuits effectively without unnecessary downtime.</p><p>One of the critical aspects of any circuit breaker is its breaking capacity; this model offers a robust 42 kA. Such capability ensures that it can interrupt fault currents safely without causing damage to itself or connected equipment.</p><p>In terms of construction, this ACB includes four poles, providing comprehensive coverage for three-phase systems plus neutral connections. The degree of protection is rated at IP30, offering adequate defense against solid objects larger than 2.5 mm but not against moisture ingress—suitable for controlled indoor environments.</p><p>The dimensions are practical yet substantial: with a width of 348 mm, height of 363.5 mm, and depth of 271 mm—allowing for integration into existing panels without excessive space demands. Weighing in at 20 kg, it&#39;s manageable during installation while still being sturdy enough for long-term use.</p><p>Power loss is an important consideration as it impacts energy efficiency; this unit incurs only 156 W under normal operating conditions—a testament to its design optimization aimed at minimizing wasteful heat generation.</p><p>Conforming to IEC 309 standards ensures that this product adheres to international safety and performance criteria—a crucial factor when compliance with regulatory requirements is mandatory in industrial applications.</p><p>This automatic ACB combines advanced technology with proven engineering principles to deliver reliable service across diverse scenarios where electrical continuity and safety are paramount concerns.</p>
