<p>When it comes to managing high-capacity electrical systems, selecting the right equipment is crucial. The Non-automatic Air Circuit Breaker (ACB) detailed here offers robust performance tailored for industrial and commercial applications.</p><p>This ACB is designed to handle a substantial rated current of 4000 A, making it suitable for heavy-duty operations. It operates efficiently within a rated voltage of 690 VAC, ensuring compatibility with various power systems. With a rated impulse withstand voltage of 12 kV and an insulation voltage of 1000 V, this circuit breaker provides reliable protection against overvoltage conditions.</p><p>The device features three poles, which are standard in many industrial settings, providing balanced distribution across phases. Designed with an IP30 degree of protection, this ACB offers resistance against solid objects greater than 2.5 mm but should be installed in environments where exposure to moisture or dust is limited.</p><p>For installation and maintenance ease, the terminal type is bolt-based with a tightening torque requirement of 70 N-m. This ensures secure connections that can withstand operational stresses over time. The physical dimensions—384 mm in width, 371 mm in height, and 270 mm in depth—allow for integration into existing setups without demanding excessive space.</p><p>In terms of energy efficiency and thermal management, the power loss stands at 465 W under full load conditions. This figure helps gauge the heat dissipation needs and overall energy consumption during operation.</p><p>The product adheres to IEC 309 standards and approvals, guaranteeing compliance with international safety regulations—a critical consideration for any professional seeking reliability and assurance from their equipment choices.</p><p>Weighing in at a solid yet manageable 56 kg, this circuit breaker balances durability with practicality for installation purposes. Its sturdy construction promises longevity even under frequent use scenarios typical within industrial environments.</p><p>Overall, this non-automatic ACB combines essential safety features with practical specifications to meet demanding electrical infrastructure requirements effectively.</p>
