<p>In the world of electrical engineering and industrial applications, selecting the right equipment is crucial for ensuring safety and efficiency. The MCCB (Molded Case Circuit Breaker) you&#39;re considering might just be the solution you need for your commercial or industrial setup.</p><p>This particular MCCB boasts a robust rated current of 400 A, making it suitable for medium to heavy-duty applications. Its rated impulse withstand voltage stands at 8 kV, providing resilience against transient overvoltages which can occur due to lightning strikes or switching surges. Additionally, with a rated insulation voltage of 1000 V and a rated operational voltage up to 690 VAC, this MCCB is well-equipped to handle high-stress environments.</p><p>The trip unit integrated within this breaker is the Ekip Dip LSI type. This advanced release mechanism offers reliable protection by enabling long-time, short-time, and instantaneous (LSI) tripping functions. This ensures that your system remains protected under various fault conditions without unnecessary disruptions.</p><p>With a breaking capacity of 36 kA, this breaker can safely interrupt substantial fault currents before they cause damage to your system components or pose safety risks. The front connection type simplifies installation and maintenance tasks by allowing easy access during wiring processes.</p><p>Designed with practicality in mind, this MCCB features three poles and comes in at a width of just 140 mm—compact enough for most panel installations while still maintaining an adequate degree of protection at IP20. This means it provides basic protection against solid objects larger than 12 mm but should be installed in enclosures where additional environmental protection is required.</p><p>Power loss is minimized with this model at only 19 W, reflecting its efficiency in operation—a critical consideration for energy-conscious facilities aiming to reduce their overall power consumption footprint.</p><p>Weighing in at approximately 4.82 kg, it&#39;s relatively lightweight compared to other breakers with similar specifications—making handling easier during installation or replacement procedures.</p><p>Conforming to IEC60947-2 standards ensures that it meets international safety and performance requirements expected from modern circuit breakers today. Moreover, compatibility with XT5N systems adds versatility when integrating into existing setups or planning new installations.</p><p>This comprehensive feature set makes it clear why such an MCCB could be an integral component within any sophisticated electrical distribution network seeking reliability alongside performance excellence.</p>
