<p>The S800HV series MCB is a robust solution tailored for commercial and industrial applications, designed to meet the rigorous demands of modern electrical systems. With a rated current of 25 A, this miniature circuit breaker ensures reliable protection against overloads and short circuits, safeguarding your electrical infrastructure.</p><p>Designed to withstand high impulse voltages, the S800HV boasts a rated impulse withstand voltage of 8 kV and an insulation voltage up to 1000 V. This makes it suitable for environments where voltage spikes are common. The device accommodates both 580 VAC and 1000 VAC rated voltages, providing flexibility in various applications.</p><p>One of the standout features is its breaking capacity of 4 kA at 1000 VAC, ensuring it can handle unexpected surges effectively. The release type K curve is ideal for protecting equipment with moderate inrush currents like transformers or motors.</p><p>With dimensions measuring a width of 54 mm, height of 142 mm, and depth of 82.5 mm, this MCB offers a compact design without compromising on performance. It fits seamlessly onto standard DIN rails for easy installation within electrical panels.</p><p>Safety and compliance are paramount; hence, the S800HV meets IEC/EN 60947-2 and UL 1077 standards. Its IP20 degree of protection indicates suitability for indoor use where dust ingress is minimal but direct contact with live parts needs prevention.</p><p>The operational temperature range from -25&#176;C ensures functionality across diverse environmental conditions. The housing color in RAL 7035 Grey adds a neutral aesthetic that blends well within most control cabinets.</p><p>For those concerned about energy efficiency, the power loss stands at just 8.6 W under full load conditions—an important factor when managing heat dissipation within enclosures.</p><p>Tightening torque specifications are set at an optimal level of 3.5 N-m to ensure secure connections without over-tightening risks. Additionally, cable cross-sections accommodate up to 50 sq-mm on both top and bottom terminals facilitating robust wiring solutions.</p><p>This product supports an overvoltage category III classification which implies it can endure transient overvoltages typically found in fixed installations such as distribution boards or large appliances connected directly to these systems.</p><p>In summary, if you&#39;re seeking reliability combined with adherence to international safety standards for your industrial or commercial setup—the S800HV series MCB provides peace-of-mind protection while maintaining operational excellence across varied applications.</p>
