Description

<p>When it comes to ensuring the safety and reliability of electrical installations in commercial and industrial settings, selecting the right Miniature Circuit Breaker (MCB) is crucial. The S800S series MCB stands out for its robust design and dependable performance, making it a solid choice for those seeking an effective circuit protection solution.</p><p>This MCB is rated for a current of 25 A, providing ample capacity for various applications while maintaining efficient operation. It boasts a rated insulation voltage of 690 V and operates effectively at both 400/690 VAC, accommodating diverse system requirements. With a release type C curve, this breaker offers optimal tripping characteristics suitable for protecting circuits with moderate inrush currents.</p><p>Durability is another key feature of this MCB. It has been tested to endure up to 10,000 electrical cycles, ensuring long-term reliability in demanding environments. The rated impulse withstand voltage is an impressive 8 kV, offering strong resistance against transient overvoltages commonly encountered in industrial settings.</p><p>Safety standards are met without compromise as evidenced by compliance with IEC/EN 60947-2, IEC/EN 60898-1, and UL 1077 certifications. This ensures that the product meets rigorous international safety and performance benchmarks.</p><p>The S800S series breaker also features a breaking capacity of 50 kA at 400 VAC which provides substantial fault-clearing capability essential for high-energy systems. Its short circuit capacity stands at 25 kA further emphasizing its strength under fault conditions.</p><p>Installation flexibility is provided through its DIN rail mounting type along with screw clamp terminals designed to accommodate cable cross sections up to 50 sq-mm both top and bottom. This allows easy integration into existing panels or new installations.</p><p>Measuring at a width of 81 mm, height of 95 mm, and depth of 82.5 mm with each pole having a width of just 27 mm makes it compact yet powerful enough to fit within standard distribution boards without consuming excessive space.</p><p>The housing color RAL7035 grey blends seamlessly into most panel designs while maintaining an operational temperature range from -25&amp;#176;C ensures functionality across varied environmental conditions typical in Australian climates from cooler southern regions through warmer northern areas.</p><p>Rated frequency operation occurs at standard industry level frequencies (50 Hz), supporting compatibility across different power systems found throughout commercial or industrial facilities nationwide including remote locations where reliable power management solutions are critical due their remoteness from central grid infrastructure networks thus requiring enhanced protective measures like those offered by this device’s Overvoltage Category rating Cat IV classification which signifies highest level protection available among competing products currently on market today!</p><p>In summary if you’re looking for comprehensive protection combined with proven durability then look no further than our featured model here equipped everything needed keep your operations running smoothly efficiently regardless challenges may face during course daily business activities whether large scale manufacturing plant small local enterprise alike can depend upon quality assurance provided every time choose opt use equipment manufactured under strictest guidelines possible guarantee satisfaction peace mind knowing investment well placed!</p>
