Description

<p>The S200M series MCB is a reliable choice for both commercial and industrial applications, offering robust protection and efficiency. Designed to handle a rated current of 20 A, it operates effectively within a voltage range of 400/415 VAC. Its impressive breaking capacity of 15 kA at 400 VAC ensures that it can safely interrupt high fault currents, providing peace of mind in demanding environments.</p><p>This MCB features a three-pole configuration with a curve type C, making it suitable for protecting circuits with moderate inrush currents such as lighting or small motor loads. The device conforms to key standards including AS/NZS 60898-1, AS/NZS 60947-2, and UL 1077, underscoring its compliance with rigorous safety and performance benchmarks.</p><p>With an IP20 degree of protection, the S200M series is designed for indoor use where there is minimal exposure to dust and moisture. It employs screw clamp terminals which support cable cross sections up to 35 sq-mm on both top and bottom connections. The tightening torque requirement is set at 2.8 N-m ensuring secure connections.</p><p>Compact yet sturdy in design, the dimensions measure at a width of 52.5 mm, height of 88 mm, and depth of 69 mm. This allows for efficient space utilization on DIN rail mounting systems—a common installation method in electrical panels.</p><p>Durability is another hallmark feature; this MCB boasts an electrical durability rating capable of enduring up to 20,000 cycles. It also maintains functionality across a broad ambient temperature range from -25&amp;#176;C to +55&amp;#176;C during operation and can be stored between -40&amp;#176;C to +70&amp;#176;C without compromising integrity.</p><p>Additionally equipped with an impulse withstand voltage capacity rated at 4 kV alongside an insulation voltage rating of up to 440 V—this model ensures resilience against transient overvoltages typically encountered in industrial settings.</p><p>The housing color RAL7035 grey blends seamlessly into most panel designs while maintaining aesthetic uniformity across installations. For those considering environmental factors like power loss—which stands at just 2.5 W—the S200M series strikes an admirable balance between performance efficiency and energy conservation.</p><p>Whether you&amp;#39;re upgrading existing infrastructure or planning new installations requiring dependable circuit protection solutions—the technical specifications offered by this product meet the complex needs faced by today&amp;#39;s industry professionals seeking reliability without compromise on quality or safety standards inherent within its design framework.</p>
