Description

<p>When selecting a Miniature Circuit Breaker (MCB) for commercial and industrial applications, the S200M series stands out with its robust features and reliable performance. This MCB is designed to ensure safety and efficiency in electrical systems, making it an ideal choice for professionals seeking dependable circuit protection.</p><p>The S200M MCB is rated for a current of 0.5 A, suitable for protecting circuits where precise current limitation is required. It operates effectively at a rated voltage of 400/415 VAC, accommodating common industrial voltage levels. With a rated insulation voltage of 440 V and an impulse withstand voltage of 4 kV, this breaker ensures high resilience against transient overvoltages.</p><p>Engineered to handle demanding conditions, the MCB boasts a breaking capacity of 15 kA at 400 VAC, providing robust fault interruption capability. Its short circuit capacity reaches up to 10 kA, ensuring that it can manage unexpected surge conditions without compromising safety.</p><p>The device has three poles and fits neatly on DIN rails with its compact dimensions: a width of 52.5 mm, height of 88 mm, and depth of 69 mm. It maintains an IP20 degree of protection against solid objects larger than 12 mm while offering ease in installation due to its standard DIN rail mounting type.</p><p>This MCB adheres strictly to international standards including AS/NZS 60898-1, AS/NZS 60947-2, and UL 1077 certifications—assuring compliance with rigorous quality benchmarks essential in Australia’s technical landscape.</p><p>Designed for flexibility in wiring solutions, the cable cross-section accommodates up to 35 sq-mm both top and bottom connections while supporting bulbar cross sections up to 10 sq-mm each side. The pole width measures at just under two centimeters (17.5 mm), optimizing space within control panels without sacrificing functionality or safety.</p><p>Withstanding environmental challenges typical in industrial settings is crucial; hence this unit supports operation across various frequencies (50/60 Hz) while maintaining energy efficiency with minimal power loss rated at only about one watt (1.1 W).</p><p>Safety considerations are further enhanced by its Curve Type D characteristic which ensures protection against high inrush currents typically found in motor start-ups or transformer energizing scenarios—a valuable feature when dealing with inductive loads prevalent across industries.</p><p>Housing comes in RAL7035 grey—a neutral tone that blends seamlessly into most installation environments—while adhering to IP3 degree pollution standards indicating suitability even amidst moderate dust exposure levels commonly encountered onsite.</p><p>In summary, whether you’re upgrading existing installations or embarking on new projects within commercial or industrial spheres—the S200M series offers reliability backed by stringent compliance credentials alongside practical design elements tailored towards enhancing operational dependability throughout your electrical infrastructure systems.</p>
