<p>When selecting an MCB (Miniature Circuit Breaker) for your commercial or industrial application, understanding the technical specifications and capabilities is crucial. The S800S series MCB stands out with its robust features tailored for demanding environments.</p><p>This MCB boasts a rated current of 32 A, making it suitable for medium-load applications. Its capability to withstand impulse voltages up to 8 kV ensures resilience against transient overvoltages, which is vital in maintaining system integrity during electrical disturbances. With a rated insulation voltage of 690 V and operational voltage ranging between 400/690 VAC, this circuit breaker efficiently handles high-voltage systems.</p><p>The release type C indicates that this MCB is designed to handle normal start-up currents without tripping unnecessarily, providing reliable protection and minimizing downtime in your operations. It offers a breaking capacity of 50 kA at 400 VAC, showcasing its ability to interrupt significant fault currents effectively.</p><p>In terms of physical dimensions, the device measures 81 mm in width, 95 mm in height, and has a depth of 82.5 mm. This compact size facilitates easy installation on standard DIN rails while optimizing panel space usage. The housing comes in RAL 7035 grey color, blending seamlessly into most industrial settings.</p><p>Safety and durability are highlighted by its degree of protection IP20 and electrical durability rated at an impressive 10,000 cycles. It also adheres to stringent industry standards including IEC/EN 60947-2, IEC/EN 60898-1, and UL 1077 certifications ensuring compliance with global safety regulations.</p><p>Designed with screw clamp terminals supporting cable cross sections up to 50 sq-mm both top and bottom ensures secure connections under varying load conditions. The tightening torque specification is set at a precise 3.5 N-m ensuring optimal contact pressure without damaging conductors.</p><p>Its short circuit capacity stands at a robust level with ratings of both the rated short circuit current at an impressive figure of up to 50 kA providing peace of mind against potential overloads or faults within your system infrastructure. Additionally the overvoltage category rating sits comfortably at level four indicating suitability even under severe overvoltage conditions typically encountered in industrial scenarios.</p><p>Operationally versatile it functions reliably across temperatures from -25&#176;C allowing deployment within diverse environmental contexts whether indoor or outdoor installations demand such flexibility from their protective devices alike found here too!</p><p>All these attributes combined make this product not only efficient but also durable enough meet rigorous demands placed upon them day-in-day-out throughout lifetime service expectancy ultimately offering value investment choice discerning professionals require when specifying solutions today tomorrow alike!</p>
