Description

<p>The MCCB (Molded Case Circuit Breaker) you&amp;#39;re considering is a robust option for industrial and commercial applications, designed to provide reliable protection and control over electrical circuits. With a rated current of 250 A, this device ensures efficient operation across various load conditions.</p><p>Engineered for resilience, it boasts a rated impulse withstand voltage of 8 kV and an insulation voltage of 800 V, making it well-suited for environments where high voltages are present. The MCCB operates effectively at both AC and DC voltages with ratings up to 690 VAC or 500 VDC.</p><p>This model features a thermal-magnetic (TM) release type with an adjustable current setting range between 175-250 A. The trip unit is TMD (Thermal Magnetic Discrimination), ensuring precise response to overloads or short circuits while minimizing unnecessary trips.</p><p>A key aspect of its design is the breaking capacity of 50 kA, which provides substantial protection against fault currents. This level of performance ensures that your systems remain secure under challenging conditions.</p><p>Designed with practicality in mind, the MCCB has three poles and uses front connections for ease of installation. It incorporates bolt-type terminals that support main circuit connecting capacities ranging from 85 to 192 sq-mm, allowing flexibility in wiring configurations.</p><p>With dimensions including a width of just 105 mm, this compact device fits seamlessly into existing setups without demanding excessive space. Despite its sturdy construction, it maintains a manageable weight of only 1.7 kg.</p><p>The degree of protection is rated at IP20, offering basic protection against solid objects larger than 12 mm but not against water ingress—ideal for indoor settings where moisture exposure is minimal.</p><p>In terms of standards compliance, this MCCB adheres to IEC60947-2 specifications, assuring you that it meets international safety and performance benchmarks. Its power loss stands at an efficient 17.8 W during operation.</p><p>Furthermore, it&amp;#39;s compatible with XT3S systems—a testament to its versatility in integration with broader electrical networks. Operating efficiently within frequency ranges of both 50 Hz and 60 Hz adds another layer to its adaptability across different regions or applications.</p><p>Overall, this MCCB represents a solid choice for those seeking reliability combined with technical excellence in their electrical distribution needs.</p>
