<p>When selecting an MCB (Miniature Circuit Breaker) for your commercial or industrial application, understanding the technical specifications is crucial to ensure compatibility and performance. The S800C series MCB offers a robust solution designed to meet demanding electrical requirements.</p><p>This MCB is rated for a current of 50 A, making it suitable for moderate load applications. It operates at a rated voltage of 230/400 VAC and can withstand impulse voltages up to 8 kV, ensuring resilience against transient over-voltages. With its rated insulation voltage set at 500 V, it provides reliable insulation under standard operating conditions.</p><p>The S800C series boasts a breaking capacity of 25 kA at 400 VAC, which is essential for handling fault conditions without compromising safety. Its short circuit capacity stands at an impressive 15 kA, providing additional assurance in high-stress scenarios.</p><p>Constructed with three poles and featuring a C curve type characteristic, this MCB effectively handles inductive loads with low inrush currents typically found in industrial settings. The product&#39;s dimensions are compact yet substantial: with a width of 81 mm, height of 95 mm, and depth of 82.5 mm.</p><p>For installation flexibility, the MCB mounts on DIN rails and supports screw clamp terminals with a tightening torque requirement of 3.5 N-m. This ensures secure connections while accommodating cable cross-sections up to 50 sq-mm both top and bottom.</p><p>In terms of durability and protection standards, the S800C series meets AS/NZS 60898-1, AS/NZS 60947-2, and UL1077 certifications—guaranteeing compliance with international safety norms. The device features an IP20 degree of protection against solid objects larger than 12mm but requires placement within appropriate enclosures for enhanced environmental resistance.</p><p>Operating efficiently across temperatures from -25&#176;C to +60&#176;C (with storage capabilities down to -40&#176;C), this MCB adapts well to diverse climatic conditions typical in Australian environments. Electrical durability spans up to an impressive lifespan of approximately 6000 cycles—ensuring long-term reliability even under frequent switching operations.</p><p>Finished in RAL7035 grey housing color that blends seamlessly into most panel designs; it maintains aesthetics without sacrificing functionality or safety considerations associated with industrial equipment installations.</p><p>Overall if you&#39;re seeking dependable circuit protection suited specifically towards commercial or heavy-duty usage scenarios then considering inclusion from ABB’s versatile lineup such as their reputable “S800C” collection could be advantageous given these outlined attributes aligning directly alongside anticipated operational needs encountered routinely within respective domains served by practitioners throughout Australia today!</p>
