<p>In the realm of commercial and industrial electrical systems, selecting the right Miniature Circuit Breaker (MCB) can significantly impact safety and efficiency. The S800N series MCB is a robust choice for those seeking reliable performance in demanding environments. With its rated current of 63 A, this MCB is well-suited for various applications requiring consistent power management.</p><p>Designed to handle a rated impulse withstand voltage of 8 kV, the S800N ensures resilience against transient overvoltages that might occur in an industrial setting. It operates efficiently within a rated insulation voltage of 690 V and accommodates dual voltage ratings at 400/690 VAC, making it versatile for different system requirements.</p><p>The breaking capacity stands strong at 36 kA at 400 VAC, providing ample protection against short circuits. This feature is crucial in maintaining system integrity under fault conditions. Furthermore, its electrical durability spans up to 6000 cycles, ensuring long-term reliability and minimal maintenance interruptions.</p><p>This MCB features three poles with a curve type C characteristic, which balances between fast response to overloads while avoiding unnecessary tripping during normal operation fluctuations—ideal for both commercial and industrial contexts where equipment protection is paramount.</p><p>Installation is straightforward with its DIN rail mounting type. The screw clamp terminals are designed to accommodate cable cross sections up to 50 sq-mm on both the top and bottom ends, ensuring secure connections with a tightening torque of 3.5 N-m.</p><p>With dimensions measuring a width of 81 mm, height of 95 mm, and depth of 82.5 mm along with an individual pole width of just 27 mm, this MCB offers compactness without sacrificing functionality or performance. Its housing comes in RAL 7035 grey—a standard hue that blends seamlessly into most control panels.</p><p>The S800N series complies with key standards such as AS/NZS 60898-1 and AS/NZS 60947-2—assurances that it meets essential safety and operational benchmarks required by Australian regulations.</p><p>Operating reliably across ambient temperatures from -25&#176;C to +60&#176;C—and capable of storage between -40&#176;C to +70&#176;C—the S800N adapts effortlessly to varying environmental conditions typical in Australia’s diverse climate zones.</p><p>Finally, the degree of protection offered includes IP20 for general ingress resistance complemented by IP3 pollution degree rating—adequate shielding against dust exposure common in many industrial settings.</p><p>For professionals seeking dependable circuit protection solutions that align with stringent technical specifications while offering ease-of-use installation features—the S800N series presents itself as an optimal choice within its class.</p>
