<p>When it comes to selecting the right Molded Case Circuit Breaker (MCCB) for your industrial or commercial needs, understanding the technical specifications is crucial. This MCCB offers a robust set of features designed to ensure reliable performance and safety in demanding environments.</p><p>With a rated current of 50 A, this MCCB is well-suited for various applications requiring consistent electrical management. Its rated impulse withstand voltage stands at 8 kV, providing excellent protection against transient overvoltages often encountered in industrial settings. The device also boasts a high-rated insulation voltage of 1000 V, ensuring safe operation under normal conditions.</p><p>The MCCB supports both AC and DC operations with rated voltages of 690 VAC and 500 VDC respectively, making it versatile across different power systems. It features a thermal-magnetic (TM) release type with an adjustable trip unit labeled as TMA, allowing for precise customization based on specific load requirements.</p><p>Power efficiency is highlighted by its low power loss of just 4.09 W, which contributes to reduced heat generation and energy consumption during operation. The breaker accommodates four poles and has an impressive breaking capacity of 50 kA, capable of handling significant fault currents without compromising system integrity.</p><p>Designed with convenience in mind, the front connection type simplifies installation processes while maintaining secure connections through bolt-type terminals. With dimensions measuring at a width of only 120 mm and weighing in at just 1.45 kg, this MCCB ensures easy integration into existing setups without demanding excessive space or adding unnecessary weight.</p><p>Protection standards are met with an IP20 degree rating that safeguards against solid foreign objects greater than 12 mm but does not provide protection against water ingress—ideal for controlled indoor environments where dust ingress may be more prevalent than moisture concerns.</p><p>Compliance with IEC60947-2 standards guarantees adherence to international quality benchmarks for low-voltage switchgear components—a testament to its reliability and operational excellence within specified parameters.</p><p>This MCCB operates efficiently across standard frequencies ranging from 50 Hz to 60 Hz while being compatible with XT2S systems—offering flexibility when integrating into established infrastructures or planning new installations altogether.</p><p>The product&#39;s rated short circuit current ranges between 300-500 A alongside a current setting range matching these values; users can confidently tailor configurations according to unique application demands without sacrificing performance stability throughout usage cycles consistently over timeframes anticipated by professionals globally today!</p><p>Main circuit connecting capacities vary between sizes from approximately thirty-two point five square millimeters up towards one hundred square millimeters depending upon required connectivity specifications per project scope considerations involved therein accordingly!</p>
