<p>When selecting an MCCB (Molded Case Circuit Breaker) for industrial or commercial applications, understanding the technical specifications is crucial. This particular MCCB is designed to meet the demands of modern electrical systems with efficiency and reliability.</p><p>With a rated current of 125 A, this MCCB is robust enough to handle substantial electrical loads while ensuring system safety. Its rated impulse withstand voltage stands at 8 kV, providing excellent resilience against transient over-voltages typically caused by lightning strikes or switching surges. The rated insulation voltage of 1000 V ensures effective isolation during maintenance or fault conditions.</p><p>Operating within a versatile range of voltages—690/750 VAC/VDC—this breaker can be integrated into various setups, whether alternating current (AC) or direct current (DC). The release type M offers dependable protection by tripping in response to overloads or short circuits, safeguarding your equipment and infrastructure.</p><p>Efficiency is further enhanced with a power loss of only 7.44 W, minimizing energy waste and heat generation. The device features three poles, making it suitable for three-phase systems commonly used in industrial settings.</p><p>A noteworthy aspect is its impressive breaking capacity of 70 kA, which indicates the ability to interrupt high fault currents without damage—a critical factor in maintaining system integrity under extreme conditions. Front connection type simplifies installation and wiring processes.</p><p>The degree of protection offered by IP20 means that while it&#39;s protected against solid objects over 12 mm like fingers or tools, it should be mounted in an enclosure for environments where higher protection levels are required. Bolt terminals provide secure connections essential for stable operation.</p><p>Measuring 105 mm in width and weighing 2.5 kg, this MCCB balances compactness with durability—ideal for space-constrained installations without compromising on performance standards set by IEC60947-2 compliance.</p><p>Compatible with XT4H units, it supports a main circuit connecting capacity ranging from 85 to 200 sq-mm cables—a testament to its adaptability across different cable sizes and configurations. Operating effectively at frequencies between 50/60 Hz ensures broad applicability across global power grids.</p><p>In summary, this MCCB offers reliable performance tailored for demanding environments requiring high breaking capacities and robust design features—all while complying with international standards for safety and quality assurance.</p>
