<p>The S800HV series MCB is a robust solution for commercial and industrial applications, designed to meet the demanding needs of these environments. With a rated current of 8 A, it provides reliable protection for electrical circuits against overloads and short circuits. This miniature circuit breaker (MCB) is engineered with precision, ensuring efficient performance across various operational conditions.</p><p>One of the standout features is its high-rated impulse withstand voltage of 8 kV, which enhances its resilience against transient overvoltages typically caused by lightning strikes or switching surges. The device operates effectively within a rated insulation voltage up to 1000 V and supports rated voltages of both 580 VAC and 1000 VAC, offering flexibility in different installation scenarios.</p><p>The MCB&#39;s release type is K curve, suited for applications where inrush currents are expected without causing unnecessary tripping. It boasts a breaking capacity of 4 kA at 1000 VAC, making it capable of handling significant fault levels safely. The power loss is minimal at just 1.7 W, contributing to energy efficiency in your system.</p><p>Designed with practicality in mind, this single-pole device has dimensions optimized for space-saving installations: a width of 27 mm, height of 142 mm, and depth of 82.5 mm. Its screw clamp terminal type ensures secure connections with a tightening torque specification set at 3.5 N-m.</p><p>Safety standards are paramount; hence this product complies with AS/NZS 60947-2 and UL 1077 certifications, assuring you that it meets rigorous international safety standards. Additionally, the degree of protection offered by IP20 safeguards against finger contact with live parts while maintaining adequate ventilation for heat dissipation.</p><p>For ease in installation and maintenance, the MCB mounts on standard DIN rails—streamlining integration into existing panels or systems—and accommodates cable cross-sections up to 50 sq-mm on both top and bottom terminals. The housing comes in RAL7035 grey color providing an aesthetically pleasing finish that blends seamlessly into most panel designs.</p><p>This product also features an overvoltage category rating of III which indicates suitability for use in fixed installations such as distribution boards or industrial control equipment where higher transient voltages may be encountered due to external influences like inductive load switching or motor starting operations.</p><p>Operating efficiently across temperatures from -25&#176;C upwards ensures reliability even under harsh environmental conditions prevalent within industrial settings across Australia’s diverse climate zones.</p><p>In summary: If you&#39;re looking for dependable circuit protection tailored specifically towards commercial/industrial needs—the S800HV series should certainly be considered as part of your electrical solutions toolkit!</p>
