<p>In the realm of industrial and commercial electrical systems, choosing the right equipment is crucial for ensuring safety and efficiency. The MCCB (Molded Case Circuit Breaker) in question is a robust solution designed to meet demanding requirements with precision and reliability.</p><p>The device offers a rated current of 125 A, making it suitable for various applications where consistent performance is essential. It boasts a notable breaking capacity of 70 kA, ensuring that it can handle significant fault conditions without compromising system integrity.</p><p>With a rated impulse withstand voltage of 8 kV and an insulation voltage of 800 V, this MCCB provides substantial protection against electrical surges, enhancing the safety of your installations. Its versatility extends to its rated voltage capabilities, supporting both AC (690 VAC) and DC (500 VDC) environments.</p><p>The trip unit features TMD (Thermal Magnetic Trip Unit), known for its reliability in protecting circuits from overloads and short circuits by leveraging thermal-magnetic release mechanisms. This ensures swift response to fault conditions while maintaining operational continuity under normal loads.</p><p>This MCCB&#39;s connection type is front-facing with bolt terminals, facilitating straightforward installation within panels or enclosures. Its four-pole design further enhances its adaptability across different circuit configurations. Despite its robust capabilities, it maintains a compact form factor with a width of just 101.6 mm.</p><p>Rated at IP20 for degree of protection, this device is safeguarded against solid objects larger than 12 mm but should be installed within appropriate enclosures for optimal environmental protection. The weight stands at only 1.4 kg, making handling and installation manageable without sacrificing durability.</p><p>Engineered to comply with IEC60947-2 standards, this MCCB meets international benchmarks for quality and safety in low-voltage switchgear applications. Its power loss rating at full load operation is kept minimal at just 10.7 W—an efficient choice that contributes to overall energy savings in your system design.</p><p>Operating seamlessly on both standard frequencies—50/60 Hz—it fits well into global projects without requiring additional modifications or considerations regarding frequency compatibility.</p><p>Designed specifically for use with XT1H frames or similar setups, this product ensures compatibility and ease when integrating into existing systems or new builds alike. Furthermore, the current setting range between 87.5-125 A allows fine-tuning according to specific operational needs while the main circuit connecting capacity accommodates conductors ranging from 45.5 sq-mm up to 80 sq-mm—a testament to its flexibility across diverse wiring scenarios.</p><p>For professionals seeking reliable performance backed by rigorous standards compliance in their electrical infrastructure projects—this MCCB proves itself as an indispensable component worthy of consideration.</p>
