ABB S202MK4UC Miniature Circuit Breaker 10 kA at 400VAC 2-P 4A 400/415VAC K-Curve

<p>The S200MUC series Miniature Circuit Breaker (MCB) is designed to meet the demanding requirements of industrial applications. With a rated current of 4 A and a rated voltage of 400/415 VAC, this MCB ensures reliable protection for electrical circuits against overloads and short circuits.</p><p>Engineered for durability, it features a breaking capacity of 15 kA at 400 VAC, making it suitable for high-demand environments where robust performance is critical. The device&amp;#39;s power loss is kept minimal at just 2.78 W, promoting energy efficiency in your installations.</p><p>This MCB comes with two poles and adheres to key standards including CSA 22.2 No. 235, IEC/EN 60947-2, and UL 1077, ensuring compliance with international safety norms. Its degree of protection is rated IP20, safeguarding the internal components from dust ingress while maintaining operational integrity.</p><p>Installation is straightforward thanks to its screw clamp terminal type which supports secure connections with a tightening torque requirement of 2.8 N-m. The compact dimensions—35 mm width by 88 mm height by 69 mm depth—allow for efficient use of panel space without compromising on performance or accessibility.</p><p>Designed to operate effectively within an ambient temperature range from -25&amp;#176;C to +55&amp;#176;C and withstand storage conditions from -40&amp;#176;C to +70&amp;#176;C, this MCB offers versatility across various environmental conditions. The impulse voltage rating stands at an impressive 4 kV while the short circuit capacity reaches up to 10 kA.</p><p>The K curve type ensures that this breaker can handle inductive loads prevalent in industrial settings such as motors or transformers without nuisance tripping. Additionally, the degree of pollution rating at IP3 adds another layer of assurance regarding its resilience in less-than-ideal atmospheric conditions.</p><p>Finished in RAL 7035 grey housing colour, it blends seamlessly into existing setups while providing clear visual indications during inspections or maintenance checks.</p><p>Whether you&amp;#39;re upgrading an existing system or designing new installations from scratch within industrial contexts requiring precise circuit management solutions—the S200MUC collection delivers reliability backed by rigorous testing and adherence to global standards—all without sacrificing ease-of-use or installation flexibility.</p>
