<p>When selecting a Miniature Circuit Breaker (MCB) for commercial or industrial applications, the S800HV series stands out with its robust specifications and reliable performance. This MCB is designed to meet the demands of modern electrical systems, offering a blend of efficiency and safety.</p><p>Rated at 40 A, this MCB ensures optimal current management within your system. It supports dual voltage ratings of 580 VAC and 1000 VAC, making it versatile for various setups. The rated impulse withstand voltage is an impressive 8 kV, providing strong protection against transient overvoltages.</p><p>Safety is further enhanced with a breaking capacity of 4 kA at 1000 VAC, ensuring that in case of fault conditions, the circuit breaker can interrupt high currents effectively. The device adheres to rigorous standards such as IEC/EN 60947-2 and UL 1077, highlighting its compliance with international safety regulations.</p><p>With three poles and a curve type K release characteristic, this MCB is well-suited for protecting circuits with inductive loads where short-circuit currents may be higher than normal. Its IP20 degree of protection ensures that the device is safe from finger contact and helps prevent accidental interference.</p><p>Installation is straightforward thanks to its DIN rail mounting type. The dimensions—81 mm width, 142 mm height, and 82.5 mm depth—allow it to fit seamlessly into standard enclosures without occupying excessive space. Additionally, the tightening torque requirement of 3.5 N-m facilitates secure connections.</p><p>The S800HV series also features an operational temperature range from -25&#176;C upwards, making it adaptable to diverse environmental conditions found across Australia’s varied climates.</p><p>Cable management is simplified with provisions for cable cross sections up to 50 sq-mm on both top and bottom terminals. Furthermore, the housing color RAL 7035 Grey ensures a neutral appearance that blends well within most electrical cabinets.</p><p>This MCB&#39;s power loss stands at just 11.1 W under full load conditions—a testament to its energy-efficient design which minimizes heat generation during operation.</p><p>Lastly, categorized under Overvoltage Category III and Degree of Pollution IP2 rating indicates robustness against varying degrees of pollution in industrial environments while maintaining high insulation integrity.</p><p>In summary: If you require an efficient solution capable of handling demanding electrical environments safely while adhering strictly to international standards—the S800HV series MCB offers all these benefits succinctly packaged into one reliable product suitable for both commercial &amp; industrial use cases without compromise on quality or performance.</p>
