<p>In the realm of commercial and industrial electrical systems, precision and reliability are paramount. The S800N Series MCB (Miniature Circuit Breaker) is a robust choice for professionals seeking dependable circuit protection. Designed with a focus on safety and efficiency, this MCB is engineered to meet demanding standards in various applications.</p><p>The S800N MCB features a rated current of 40 A, making it suitable for moderate power distribution tasks. Its rated voltage spans from 400 to 690 VAC, allowing flexibility across different electrical setups. With a breaking capacity of 36 kA at 400 VAC, this breaker ensures reliable interruption of fault currents, safeguarding your circuits against potential overloads and short circuits.</p><p>Constructed to withstand harsh conditions, the device boasts an impressive rated impulse withstand voltage of 8 kV and an insulation voltage of up to 690 V. This resilience is further backed by its compliance with IEC/EN 60947-2 and IEC/EN 60898-1 standards, ensuring it meets international quality benchmarks.</p><p>The S800N&#39;s IP20 degree of protection indicates that it&#39;s designed for environments where dust ingress must be minimized while still offering adequate safety from accidental contact with live parts. It also features an IP3 degree of pollution rating, highlighting its capability to operate efficiently even in moderately polluted atmospheres.</p><p>For ease of installation, this MCB mounts seamlessly onto DIN rails—a standard in many electrical cabinets—allowing straightforward integration into existing systems. The tightening torque requirement stands at a precise 3.5 N-m, ensuring secure connections without over-tightening.</p><p>Physically compact yet powerful, the MCB measures 54 mm in width, with each pole occupying just 27 mm—ideal for space-constrained panels. At dimensions of height: 95 mm and depth: 82.5 mm, it offers substantial performance without compromising on footprint efficiency.</p><p>Durability is another hallmark; the unit promises electrical durability up to an impressive count of 6000 cycles—translating into long-term reliability under frequent operation scenarios typical in industrial settings.</p><p>Cable management is simplified with provisions for cable cross sections up to 50 sq-mm both top and bottom sides—accommodating substantial wiring needs effortlessly. Moreover, its RAL7035 grey housing not only provides aesthetic neutrality but also aligns well with most equipment designs found in commercial installations.</p><p>Operating within frequency ranges between 50/60 Hz adds versatility across different regional power supplies while maintaining consistent performance metrics throughout usage life cycles.</p><p>For those prioritizing energy efficiency alongside functionality—the power loss remains minimal at just about 3.7 W during operation—a testament to its design focused on reducing unnecessary energy consumption whilst maximizing output efficacy within operational parameters set forth by industry requirements such as curve type C classification which caters specifically towards general load protection including motors or transformers typically seen within commercial-industrial domains alike thereby enhancing overall system robustness significantly through meticulous engineering prowess encapsulated succinctly herein via Collection: S800N Series</p>
