Description

When it comes to selecting a reliable Miniature Circuit Breaker (MCB) for your commercial or industrial applications, the S800S series offers robust performance and reliability. Designed to meet demanding electrical requirements, this MCB is engineered with precision to ensure safety and efficiency in various settings. The MCB is rated for a current of 63 A, making it suitable for medium-duty applications. It operates at rated voltages of 400/690 VAC and can withstand an impulse voltage of 8 kV. This ensures that the device can handle transient overvoltages effectively, providing protection against surges. One of the standout features is its breaking capacity of 50 kA at 400 VAC, which guarantees high-level protection against short circuits. The release type C curve makes it ideal for environments where moderate inrush currents are expected. With a degree of protection rated at IP20, this MCB is safeguarded against solid objects larger than 12 mm but should be installed in enclosures when used in dusty or moist environments. Its terminal type utilizes screw clamps with a tightening torque requirement of 3.5 N-m, ensuring secure connections with minimal maintenance. The S800S series adheres to several international standards such as IEC/EN 60947-2, IEC/EN 60898-1, and UL 1077, confirming its compliance with global safety and performance benchmarks. In terms of physical dimensions, the unit measures a width of 81 mm by height of 95 mm by depth of 82.5 mm. The pole width stands at a compact 27 mm per pole allowing efficient use within panel spaces on DIN rail systems. This MCB also boasts an impressive electrical durability rating capable of enduring up to 6000 cycles under normal conditions—an indicator that it’s built for longevity even under frequent operation scenarios. Additionally, its short circuit capacity is noted at both standard (25 kA) and rated (50 kA) levels providing versatility across different installations. Designed following environmental considerations too; it functions optimally within temperatures ranging from -25°C upwards making sure operations remain unaffected during extreme weather conditions typical across Australia’s varied climates. For wiring flexibility accommodating large conductor sizes up till cable cross sections measuring up-to-50 sq-mm top/bottom further simplifies installation processes while reducing potential points-of-failure associated often due improper terminations especially critical within complex setups involving multiple loads distributed over extensive areas like those found commonly throughout industrial plants/factories alike! Finished off aesthetically pleasing touch via housing color coded RAL7035 grey seamlessly blending into any existing infrastructure without drawing unnecessary attention away core functionalities delivered reliably time again courtesy advanced engineering principles employed throughout entire design process ultimately aimed delivering superior user experience each every instance deployed out field today tomorrow beyond!
