Description

<p>When it comes to selecting a reliable Miniature Circuit Breaker (MCB) for your commercial or industrial applications, the S800N series stands out with its robust specifications and reliable performance. This MCB is designed to meet the rigorous demands of modern electrical systems, ensuring safety and efficiency.</p><p>Starting with its core parameters, this MCB handles a rated current of 20 A and operates efficiently within a voltage range of 400/690 VAC. It boasts an impressive breaking capacity of 36 kA at 400 VAC, making it well-suited for environments where high fault levels can occur. The device also offers a rated impulse withstand voltage of 8 kV, providing excellent protection against transient overvoltages.</p><p>The construction details are equally noteworthy. With three poles and a width of 81 mm, height of 95 mm, and depth of 82.5 mm, this compact unit fits seamlessly into standard DIN rail mounting systems. The screw clamp terminal type ensures secure connections with a tightening torque specification of 3.5 N-m.</p><p>Durability is another key feature; the S800N series delivers an electrical durability rating capable of enduring up to 10,000 cycles. Its short circuit capacity is rated at an impressive 25 kA, underscoring its capability to handle unexpected surges effectively.</p><p>For those concerned about environmental resilience, this MCB operates reliably in ambient temperatures ranging from -25&amp;#176;C to +60&amp;#176;C and can be stored in conditions between -40&amp;#176;C and +70&amp;#176;C without degradation in performance. The device also adheres to IP20 protection standards against solid objects larger than 12mm while offering IP3 degree pollution resistance.</p><p>In terms of compliance, it meets AS/NZS standards including AS/NZS 60898-1 and AS/NZS 60947-2—ensuring adherence to Australian regulations for low-voltage switchgear components.</p><p>The housing color RAL7035 grey gives it a professional appearance suitable for both industrial settings as well as commercial installations where aesthetics might be considered alongside functionality.</p><p>Finally addressing cable management needs; this model supports cable cross sections up to 50 sq-mm both top and bottom—providing flexibility during installation processes across various setups whether upgrading existing infrastructure or implementing new systems altogether.</p><p>With all these features combined under one roof—the S800N series proves itself not just another choice but rather an intelligent investment towards enhanced operational reliability within any given setup demanding uncompromised quality assurance every step along way forward!</p>
