<p>When it comes to selecting the right Molded Case Circuit Breaker (MCCB) for your industrial or commercial needs, understanding the specifications is crucial. This MCCB offers a robust solution with its well-rounded features designed for reliability and safety in electrical systems.</p><p>Starting with the basics, this MCCB is rated for a current of 63 A, making it suitable for a variety of applications where consistent performance is key. It boasts a rated impulse withstand voltage of 8 kV and an insulation voltage rating of 800 V, ensuring that it can handle significant electrical stresses without compromising safety or functionality.</p><p>The device operates at a rated voltage of up to 690 VAC or 500 VDC, providing flexibility across different power systems. With thermal-magnetic (TM) release type and thermal-magnetic trip unit (TMD), you can expect reliable protection against overloads and short circuits.</p><p>Power loss is minimal at just 4.3 W, which contributes to energy efficiency—a critical factor in modern installations aiming to reduce operational costs. The breaker supports four poles and has an impressive breaking capacity of 25 kA.</p><p>For ease of installation and maintenance, the connection type is front-facing with bolt terminals, allowing straightforward integration into existing setups. The device&#39;s width measures at 101.6 mm, making it compact enough for space-constrained environments while offering sufficient room for safe operation.</p><p>This MCCB adheres to IEC60947-2 standards and approvals, ensuring compliance with international safety regulations—an essential consideration when working in diverse geographical regions like Australia. The degree of protection stands at IP20, indicating adequate protection against solid objects larger than 12 mm but not against water ingress.</p><p>Weighing in at only 1.4 kg means it&#39;s lightweight yet durable enough to withstand typical industrial conditions without adding unnecessary load on mounting structures.</p><p>Operating within a frequency range of 50/60 Hz ensures compatibility with both domestic and international power grids. It&#39;s also compatible with XT1C devices—providing versatility if you&#39;re looking to integrate multiple components from similar product lines.</p><p>With a rated short circuit current capacity of up to 630 A and a current setting range between 44.1-63 A, this MCCB provides ample headroom for adjustments as per specific application requirements—whether you&#39;re dealing with fluctuating loads or stable operations.</p><p>Finally, the main circuit connecting capacity ranges from 45.5 sq-mm to 80 sq-mm—offering flexibility when choosing cables based on your system&#39;s demands without compromising on performance or safety standards.</p>
