<p>The Automatic Air Circuit Breaker (ACB) you&#39;re considering is a robust and reliable choice for industrial and commercial applications, designed to handle demanding electrical environments with precision. With a rated current range of 800 to 2000 A, this ACB offers flexibility in accommodating various load requirements, making it suitable for a wide array of installations.</p><p>One of its standout features is the impressive rated impulse withstand voltage of 12 kV, ensuring that the breaker can endure transient over-voltages without compromising performance. The rated insulation voltage stands at 1000 VAC, providing ample protection against electrical breakdowns under normal operating conditions.</p><p>In terms of safety and reliability during short circuits, this ACB boasts a rated short-time withstand current of 85 kA. This capability ensures that your system remains protected even under severe fault conditions. Complementing this is the breaking capacity of 100 kA, allowing the breaker to safely interrupt high fault currents without damage.</p><p>Operating at a rated voltage of up to 690 VAC, this device supports high-power systems commonly found in industrial settings. The Ekip Touch LSIG trip unit integrates seamlessly into the system architecture, offering advanced protection features such as long-time, short-time, instantaneous and ground fault protection modes. This ensures precise control over fault detection and interruption timing.</p><p>Power loss is an important consideration in any electrical system; here it is maintained at an efficient level with only 450 W lost during operation. This efficiency contributes to reduced energy consumption and operational costs over time.</p><p>The design incorporates four poles which provide balanced power distribution across phases while enhancing safety through redundancy. Installation flexibility is enhanced by the horizontal rear spread terminal type which simplifies connections in space-constrained environments or where existing wiring configurations are present.</p><p>Conforming to IEC 309 standards and approvals underscores its compliance with international safety regulations ensuring peace-of-mind regarding quality assurance and operational reliability.</p><p>Overall, this Automatic ACB combines durability with advanced technology tailored for those who demand consistent performance from their electrical infrastructure without compromise on safety or efficiency—all within a compact frame size E2.2 ideal for modern setups requiring space optimization yet powerful capabilities.</p>
