<p>In the realm of industrial and commercial electrical systems, choosing the right circuit protection is crucial. Enter the MCCB (Molded Case Circuit Breaker), a robust solution designed to meet demanding operational needs with precision and reliability.</p><p>This MCCB is engineered for a rated current of 400 A, offering substantial capacity for various applications. Whether dealing with AC or DC circuits, its rated voltage spans 690/750 VAC/VDC, ensuring versatile deployment across different setups. The device&#39;s rated impulse withstand voltage stands at an impressive 8 kV, making it resilient against transient overvoltages.</p><p>One of the standout features is its breaking capacity of 70 kA. This high threshold ensures that in the event of a fault condition, the MCCB can effectively interrupt excessive current flows without compromising safety or system integrity. Complementing this is a rated short circuit current range between 2000-4000 A, providing ample headroom for handling potential overloads.</p><p>The trip unit type TMA (Thermal Magnetic Adjustable) offers users flexibility in setting precise parameters tailored to specific operational requirements. With a current setting range adjustable from 280-400 A, users can fine-tune their protection strategies to match their particular load profiles.</p><p>Installation and integration are made straightforward with its front connection type and compatibility with XT5H systems. Measuring at a width of just 186 mm and weighing in at 5.6 kg, it maintains a compact profile without sacrificing performance.</p><p>The MCCB adheres to IEC60947-2 standards, underscoring its compliance with international safety and quality benchmarks—a critical consideration for any technical professional seeking reliable components.</p><p>Designed with practicality in mind, it features an IP20 degree of protection which makes it suitable for indoor environments where dust ingress needs to be minimized but not completely sealed off from moisture exposure.</p><p>Power efficiency is another highlight—this unit has a power loss rating of only 24.1 W under full load conditions. Such efficiency translates into reduced energy consumption over time while maintaining optimal performance levels.</p><p>In summary, this MCCB provides robust electrical protection capabilities suited for diverse industrial applications—offering reliability backed by rigorous standards compliance without unnecessary complexity or bulkiness often associated with high-capacity breakers.</p>
