<p>The S800S Series Miniature Circuit Breaker (MCB) is designed to meet the rigorous demands of commercial and industrial applications. With a rated current of 20 A, this robust device ensures reliable protection against overloads and short circuits, making it an essential component in electrical distribution systems.</p><p>One of the standout features of this MCB is its impressive breaking capacity of 50 kA at 400 VAC. This high level of performance ensures that even in the event of a significant fault, your system remains protected. The device operates efficiently within its rated voltage range of 400/690 VAC and can withstand impulse voltages up to 8 kV, providing added security against transient overvoltages.</p><p>Constructed for durability, the S800S boasts an electrical lifespan of up to 10,000 cycles. Its release type C curve makes it suitable for applications where moderate inrush currents are expected without unnecessary tripping—ideal for protecting lighting circuits or small motors.</p><p>In terms of installation flexibility, this MCB offers a four-pole configuration with a width spanning just 106 mm. It mounts easily onto DIN rails and accommodates cable cross sections up to 50 sq-mm on both top and bottom connections, ensuring compatibility with various wiring setups.</p><p>Safety and compliance are paramount; hence, this product adheres to standards such as IEC/EN 60947-2, IEC/EN 60898-1, and UL 1077. Additionally, it holds an IP20 degree of protection against accidental contact with live parts while maintaining an operational temperature range from -25&#176;C upwards—making it versatile across different environments.</p><p>For ease during installation or maintenance work, a tightening torque specification is provided at 3.5 N-m which helps secure connections effectively without risking damage due to overtightening.</p><p>The physical dimensions are compact yet substantial enough: standing at a height of 95 mm with depth reaching out at approximately around about only slightly more than eight centimeters deep (82.5 mm). Finished off neatly using RAL7035 grey housing color giving consistency across installations especially when used alongside other devices from within same collection series family line-up too!</p><p>Overall if you&#39;re looking into upgrading existing infrastructure needing something capable handling heavy-duty tasks then consider choosing from our trusted solution offerings here today under model number [Manufacturer Part Number].</p>
