<p>The S800S MCB is a robust solution tailored for commercial and industrial applications, offering reliable protection and performance. With a rated current of 40 A, this miniature circuit breaker (MCB) efficiently handles electrical loads in demanding environments. Its rated voltage spans 400/690 VAC, providing versatility for various installations.</p><p>This MCB boasts an impressive breaking capacity of 50 kA at 400 VAC, ensuring safety during fault conditions by effectively interrupting high short-circuit currents. The release type C makes it suitable for protecting circuits with moderate inrush currents. Furthermore, the device&#39;s electrical durability extends to 6000 cycles, promising long-term reliability.</p><p>Designed to meet international standards such as IEC/EN 60947-2, IEC/EN 60898-1, and UL 1077, the S800S series adheres to stringent quality benchmarks. It offers a degree of protection rated at IP20 and IP3 pollution degree classification, safeguarding against accidental contact with live parts while maintaining operational integrity in various environmental conditions.</p><p>The physical dimensions include a width of 106 mm, height of 95 mm, and depth of 82.5 mm. This compact size fits seamlessly into existing setups using DIN rail mounting systems. Each pole has a width of 27 mm across its four poles configuration.</p><p>For optimal performance under adverse conditions, the S800S operates within an ambient temperature range from -25&#176;C upwards. The housing color is RAL 7035 Grey which blends well with most industrial panel designs.</p><p>Additional technical specifications include a rated impulse withstand voltage and impulse voltage both at an impressive level of 8 kV—demonstrating resilience against transient overvoltages—and an insulation voltage rating up to 690 V that ensures effective isolation between conductive components.</p><p>The tightening torque requirement stands at a precise value of 3.5 N-m for secure connections; meanwhile cable cross-sections accommodate up to two sets each having top/bottom entries measuring maxed out around fifty square millimeters respectively allowing flexible wiring options without compromising on safety or efficiency aspects whatsoever!</p><p>Finally yet importantly: Overvoltage Category IV classification denotes superior robustness when dealing alongside fluctuating power supplies often encountered throughout complex network infrastructures anywhere globally speaking!</p>
