Description

<p>When it comes to selecting the right Miniature Circuit Breaker (MCB) for your commercial or industrial needs, understanding the technical specifications is key. This particular MCB from the S800S series offers a robust solution with its impressive features tailored for demanding environments.</p><p>The MCB has a rated current of 16 A, making it suitable for moderate load applications. It operates efficiently within a rated voltage range of 400/690 VAC and withstands impulse voltages up to 8 kV. The device is designed with a C-type release characteristic, ensuring reliable protection during short-circuit conditions while minimizing nuisance tripping.</p><p>This breaker boasts a significant breaking capacity of 50 kA at 400 VAC, providing ample protection against high fault currents. Its electrical durability extends up to 10,000 cycles, ensuring long-term reliability in frequent operation scenarios. The product complies with international standards such as IEC/EN 60947-2 and IEC/EN 60898-1, backed by UL 1077 approval, guaranteeing safety and performance.</p><p>The MCB’s construction includes three poles housed in RAL 7035 grey casing with an IP20 degree of protection. This ensures basic protection against solid objects while maintaining user safety during handling and installation. It fits neatly onto standard DIN rails thanks to its compact dimensions—81 mm wide, 95 mm high, and 82.5 mm deep—with each pole measuring a width of just 27 mm.</p><p>For ease of installation and maintenance, this model features screw clamp terminals that accommodate cable cross sections up to 50 sq-mm on both top and bottom connections. With a tightening torque requirement of only 3.5 N-m, securing connections is straightforward without compromising on stability.</p><p>Operating efficiently across temperatures ranging from -25&amp;#176;C upwards makes this unit versatile enough for various climates found throughout Australia’s expansive landscape. Additionally, its overvoltage category rating of IV indicates resilience against transient overvoltages typically encountered in industrial settings.</p><p>Designed specifically for commercial and industrial applications where reliability cannot be compromised upon—this MCB stands out as an ideal choice given its combination of advanced features coupled with adherence to rigorous standards ensuring peace-of-mind operation day-in-day-out within your electrical systems infrastructure.</p>
