<p>When it comes to selecting a reliable MCCB (Molded Case Circuit Breaker) for industrial and commercial applications, understanding the technical specifications is crucial. This MCCB offers a robust solution with a rated current of 40 A, making it suitable for various electrical systems. It boasts an impressive rated impulse withstand voltage of 8 kV and a rated insulation voltage of 800 V, ensuring high durability and protection against transient overvoltages.</p><p>Operating efficiently across both AC and DC systems, this MCCB supports a rated voltage of up to 690 VAC or 500 VDC. The thermal magnetic (TM) release type combined with the TMD trip unit provides effective circuit protection by responding accurately to overloads and short circuits.</p><p>With a power loss of only 2.6 W, this device maintains energy efficiency while in operation. It features four poles, allowing for comprehensive coverage in multi-phase installations. Its breaking capacity stands at 25 kA, providing reliable interruption capability during fault conditions.</p><p>The front connection type simplifies installation processes, especially when dealing with compact spaces or retrofitting existing panels. Rated at IP20 for its degree of protection, it ensures safety against solid foreign objects greater than 12 mm in size but is intended for use within enclosed environments due to its lack of water resistance.</p><p>Equipped with bolt terminals that accommodate main circuit connecting capacities ranging from 45.5 to 80 square millimeters, this MCCB is designed for secure connections that minimize maintenance needs over time. Measuring just 101.6 mm in width and weighing approximately 1.4 kg, it’s compact yet sturdy enough for demanding applications.</p><p>Adhering to IEC60947-2 standards underscores its compliance with international safety requirements—a critical factor when considering components for global projects or diverse regulatory environments.</p><p>Designed specifically as part of the XT1C series compatibility range ensures seamless integration into existing setups without compromising performance or reliability. The current setting range between 28-40 A adds flexibility in adjusting operational parameters according to specific load demands within your system architecture.</p><p>This MCCB operates effectively at frequencies between 50/60 Hz—ideal whether you&#39;re working on infrastructure supporting residential power grids or specialized industrial machinery setups requiring precise frequency management—and can handle short circuit currents up to an impressive rating of 450 A which enhances overall system resilience under stress conditions.</p>
