<p>When it comes to ensuring the safety and efficiency of electrical systems, selecting the right Miniature Circuit Breaker (MCB) is crucial. This particular MCB offers a robust solution for various industrial and commercial applications that demand reliability and performance.</p><p>Designed to handle a rated current of 63 A, this MCB is suitable for circuits requiring moderate power handling capabilities. It operates efficiently at a rated voltage of 400 V, making it compatible with standard electrical setups common in Australian industries.</p><p>The product&#39;s degree of protection is classified as IP20, which means it&#39;s safeguarded against solid objects over 12 mm in size but not protected against water ingress. This level of protection makes it ideal for indoor environments where exposure to moisture is minimal.</p><p>In terms of dimensions, the MCB measures 54 mm in width, 95 mm in height, and has a depth of 82.5 mm. These compact dimensions allow for easy integration into existing panels or distribution boards without consuming excessive space—a key consideration when planning system layouts.</p><p>One notable feature is its rated impulse withstand voltage of 8 kV, providing resilience against transient overvoltages such as those caused by lightning strikes or switching surges. This ensures continued operation under fluctuating conditions that might otherwise compromise lesser components.</p><p>The MCB also boasts a breaking capacity of 5 kA. This indicates its ability to interrupt fault currents up to this level without damage—an essential factor when considering circuit protection during short-circuit events.</p><p>Power loss stands at 12.8 W during operation—an efficient figure that minimizes energy wastage while maintaining functionality across prolonged use periods. </p><p>For those concerned with response characteristics, this model features a Curve Type B trip curve. This means it trips between three and five times the full load current rating (3-5 In), making it particularly suitable for protecting lighting circuits or other installations with low surge currents upon startup.</p><p>Overall, this MCB combines durability with precision engineering to meet diverse technical requirements typical within industrial contexts across Australia—offering peace of mind through dependable circuit management solutions tailored towards safeguarding both equipment and personnel alike.</p>
