<p>When selecting a Molded Case Circuit Breaker (MCCB) for your industrial or commercial application, understanding the technical specifications is crucial. The MCCB in question offers robust performance with its impressive rated current of 52 A, making it suitable for medium-duty electrical systems.</p><p>This breaker stands out with a high breaking capacity of 50 kA, ensuring reliable protection against short circuits and overloads. Its rated voltage spans both AC and DC applications at 690/500 VAC/VDC, providing versatility across different power systems. The rated insulation voltage is set at 1000 V, while the rated impulse withstand voltage reaches up to 8 kV, offering enhanced safety against transient overvoltages.</p><p>Designed to operate efficiently within a frequency range of 50/60 Hz, this MCCB maintains stability across standard electrical grids. It features a release type labeled as &#39;M&#39;, which typically refers to a specific mechanism or technology used within the breaker to ensure precise operation under varied conditions.</p><p>The MCCB&#39;s physical design includes three poles and front connection type for straightforward integration into existing panel setups. With an IP20 degree of protection, it provides basic ingress protection against solid objects larger than 12 mm but requires additional enclosure considerations in environments prone to dust or moisture exposure.</p><p>Installation is facilitated by bolt-type terminals that accommodate main circuit connecting capacities ranging from 32.5-100 sq-mm. This flexibility supports various conductor sizes and types commonly encountered in industrial settings.</p><p>Measuring just 90 mm in width and weighing only 1.4 kg, this compact yet sturdy unit fits seamlessly into space-constrained installations without compromising on performance or safety standards.</p><p>Adhering to IEC60947-2 standards ensures compliance with international norms for low-voltage switchgear and control gear components—an essential factor for those prioritizing quality assurance and regulatory adherence.</p><p>Additionally, this MCCB is compatible with XT2S series components, allowing for streamlined integration into broader system architectures where such compatibility may be required or beneficial.</p><p>With a power loss rating of only 4.8 W during operation, this device contributes minimally to overall system inefficiencies—a critical consideration when optimizing energy consumption across large installations.</p><p>In summary, this MCCB combines reliability with versatile functionality suited to demanding environments where safety and efficiency are paramount concerns in electrical distribution networks.</p>
