Description

When it comes to choosing the right Miniature Circuit Breaker (MCB) for your industrial or commercial needs, the S800S series offers a robust and reliable solution. This MCB is designed to handle demanding electrical environments with precision and safety. With a rated current of 50 A, this MCB ensures efficient management of electrical load while maintaining stability in your circuits. It boasts an impressive rated impulse withstand voltage of 8 kV and a rated insulation voltage of 690 V, making it suitable for high-voltage applications. The device is versatile with its dual-rated voltage capability at 400/690 VAC, accommodating various power requirements seamlessly. The S800S features a C-type release characteristic which provides optimal protection against short-circuits and overloads in circuits that experience moderate inrush currents such as motors or transformers. Its breaking capacity stands strong at 50 kA at 400 VAC, ensuring reliable interruption even under severe fault conditions. For ease of installation and maintenance, this MCB is equipped with screw clamp terminals supporting a cable cross-section of up to 50 sq-mm on both top and bottom connections. The recommended tightening torque for secure connections is set at 3.5 N-m. With dimensions measuring a compact width of 81 mm, height of 95 mm, and depth of 82.5 mm, it fits neatly within standard enclosures while adhering to space constraints. Safety standards are paramount; hence this product complies with IEC/EN 60947-2, IEC/EN 60898-1 as well as UL 1077 certifications ensuring international quality benchmarks are met. It carries an IP20 degree of protection against solid objects over 12mm like fingers or tools. The housing color RAL7035 grey not only gives it an aesthetic appeal but also aligns with common industrial equipment colors for seamless integration into existing setups. Designed for DIN Rail mounting type installations, this MCB supports easy integration into control panels or distribution boards. Operationally resilient across temperatures ranging from -25°C upwards makes it suitable for diverse environmental conditions found across Australia’s varied climate zones whether coastal areas or inland regions. Additionally notable is its remarkable electrical durability rated up to approximately six thousand cycles enhancing longevity thus reducing replacement frequency over time contributing towards cost efficiency long term investment wise especially when used extensively within commercial settings where reliability cannot be compromised upon under any circumstances whatsoever!
